Electronic Floor Scale Accuracy. How to Check and Adjust

Before using the scales for the first time you need to install, calibrate and adjust them. First remove the protective cover on the battery compartment and insert the batteries, remembering to observe proper polarity (battery and battery terminals must be the same). On the display of the scales appears marked LO when the batteries fail and need to be replaced. If the scale is used infrequently, the batteries can be removed.

Some models of scales are equipped with alternative power sources and work from the sun or from conversion of mechanical energy during weighing.

To begin operation, after the batteries have been inserted, the scale should be placed on a flat, hard surface, preferably on a level. This determines the accuracy of measurement. For example, a soft carpet is not suitable, the values will float and do not match the actual. Ideally, the scale should stand in the same place at all times. This way their position will not affect the result.

To adjust the sensor you need to press on the platform of the scale, in most scales the point you want is in the upper right corner. the display will show 88:88 and then 0.0 or just 0. This signals that they are ready for use.

Useful tips

There are a few practical guidelines to help set up a scale for home use:

  • Change where the measuring device stands. Visually a person may not even notice that the scales are not level and this leads to errors in the sensors.
  • Check the legs of the scales for a foreign object that causes malfunction.
  • Independently change the batteries in the floor scales.

For the measuring equipment to show the correct result, it is necessary to place the device on the even surface. For the rest its quality and life depends on the manufacturer and the chosen model.

Variety of electronic scales

Before proceeding to setting up the measuring equipment we should determine what categories of scales can be met in everyday life. So, most often we encounter the use of the following types:

  • Benchtop trading scales. most often we see such equipment in store halls and small retail outlets. A distinctive feature of such weighing devices are the small size and limited weighing limit.
  • Floor-type warehouse scales. used in warehouses, vegetable stores and wholesale outlets. Basically, such scales are used for weighing large loads, such as a bag of potatoes or other vegetables.
  • Electronic floor scales for reading a person’s weight. This equipment is available in almost every apartment, where people care about their own health and losing weight.

The device of electronic floor scales

The product consists of several elements. As a rule, experts distinguish the following parts of it:

The body of the product can be made of plastic, glass or metal. Each version has its own advantages. If the case is deformed, it is almost impossible to repair the scale.

The most important part of the scales are load cells. They are metal plates that are located on the back of the product.

Inside the product there is a circuit board which reads data and shows them on the display. The electronic circuit board affects the functionality of the scales. Four sensors are connected to the board. The whole construction is reliably protected by the housing. The display in most devices is black and white. It displays all the necessary information well.

How to check the scales for accuracy

A person’s weight is constantly changing. Different readings can even be observed in the morning and evening. Therefore, very often you want to know how you can check the floor electronic scales for accuracy.

In general, people draw conclusions about the correctness of the measuring device after they put various objects on the platform. But this is one of the most common mistakes. The scales are designed to correctly measure a person’s weight. That is, there is a certain type of load on the platform. Therefore, using relatively small objects, such as one kilogram of sugar or dumbbells weighing less than five to seven kilograms, it is impossible to draw correct conclusions about the work of the device, because there will be errors in the calculations.

Each model has special sensors that are installed in the legs of the device. It is these that are responsible for the accuracy and correctness of measurements.

In order to determine whether the readings are correct, you need to weigh yourself five times. At the same time it is not recommended to do:

  • Large pauses between approaches.
  • There is in the process of weighing.
  • Drinking water or a variety of beverages.
  • Changing clothes or undressing.
  • Other things that can cause an inaccurate or erroneous reading.

This will help you find out how much of an error the device is working with. This is done as follows: the smallest weighing result is subtracted from the larger value. If the device works correctly and correctly, the permissible error will be 400 grams or less. If the value is greater, you can conclude that the device as a whole is defective. Sensors are usually the problem. Use the reset button to find out. In almost all models it is on the back side of the weighbridge.

In cases where a general reset has not helped to correct inaccurate data, you can resort to these solutions to the problem:

In this case, sometimes buying a new scale is much cheaper than repairing it with your own hands or in the workshop. Especially if the sensors are broken. Criteria for choosing an accurate floor scale read here.

Method 1 Checking the Floor Scale

Set the scale to zero. Sometimes zero becomes mislaid and must be reset. There are two ways to do this, depending on what kind of scale you have. If you have an analog scale, push down on it with the palm of your hand, then remove your hand. As a result, the scale should return to zero. If this does not happen, use the little wheel usually found on the bottom of the scale or right next to the scale to turn it so the scale reads zero when there is no load. Check the scale again to see if it is set correctly.

Weigh the object with a known weight. One way to check the accuracy of a floor scale is to weigh something on it that you know its weight. An item should be big enough for the scale to “feel” it, but not too heavy so that you can effortlessly place it on the scale. For example, you can use an unopened packet of sugar or flour with the weight indicated on it. As a rule, such packs do not weigh more than a few kilograms, which is convenient for checking the scales.

    Label the packet with the weight of its contents, not including the packet itself. It doesn’t matter if the package is a light paper or plastic bag, but if the flour or sugar is packed in a heavy bag or metal jar, try something else.

You can use dumbbells or kettlebells that have the weight labeled on them. Place the weight on the scale and see what it reads.

Weigh the object several times. Scale readings may vary if weighed more than once. Take an object with a known weight, such as a weight or an unopened bag of sugar. Put it on the scale and record its reading. Then remove the object from the scale and wait until it reaches zero. Then put it back on the scale and record the reading. Make at least five weighings to verify the repeatability of the scale’s readings.

  • If the readings are inconsistent, you can increase the number of times you weigh. Take enough measurements to be sure that the scales are accurate and repeatable.

Weigh two objects at the same time. Another way to test the accuracy of a scale is to weigh two objects together. This way you can put more weight on the scale and judge its accuracy at higher values. In addition, you will check how the scales work if the mass is not uniformly distributed, which is useful when weighing, since it is not always possible to stand exactly in the middle.

    Place one object on the scale. Record the scale’s readings. Remove the object from the scale and wait until the scale reads zero. Then place the second object on the scale and record its weight. Remove the second item and wait for the scale to return to zero. Then put both items on the scale at the same time and record the reading. Add up the weight of each item and check to see if the sum is equal to their total weight.

If the sum is equal to the total weight, then the scale shows an accurate value. If these values are not equal, repeat the procedure again. If the results are repeated, it looks like your scale is consistently wrong by this amount.

Storage Conditions

When using precision devices, it is important to keep them in mind:

  • Do not expose the scale to extremes of temperature, humidity, shock, dust, or sunlight.
  • Keep the scale away from heaters.
  • Use a damp cloth to clean the platform, a dry, soft cloth for the base. Chemical or abrasive products are not recommended for use.
  • Using or storing the scale in high humidity areas or allowing liquid to get into the housing can destroy the metal parts and affect the accuracy of the measurement.
  • You should not use physical force to the scales, jump on them.

Provide proper storage conditions for your device, and then it will serve you for many years.

How to set up an electronic scale?

Nowadays electronic scales have become an integral part of human life. These devices are used both in the retail industry and in everyday life. In this article, we will tell you how to adjust electronic scales so that they show the most accurate weighing results.

Variety of electronic scales

Before you start setting up the measuring equipment, you should determine what categories of scales can be found in everyday life. So, most often we come across the use of the following types:

  • Trading desk scales. we often see such equipment in the stores or small retail outlets. The distinctive feature of such weighing instruments is their small size and limited weighing limit.
  • Floor storage scales are used in warehouses, vegetable stores and wholesale outlets. Mostly large loads are weighed on such scales, for example, a sack of potatoes or other vegetables.
  • Electronic floor scales for determining a person’s weight. This equipment is available in almost every home, where people care about their own health and losing weight.

How scales work?

The principle of operation of all scales is the same and consists in placing the load on the surface of the platform, which influences the elastic elements and provokes their deformation.

Exactly the amount of deformation produced is recorded by strain gauges.

After completing this procedure, an electric current of a certain strength is delivered to the electronic unit, which is electronically converted into a mass reading on the display.

How to set up a trade scale?

The principle of calibrating weighing equipment may vary slightly, depending on its function and type. If you are wondering how to set up a desk scale for trading, this procedure is carried out according to a fairly simple algorithm:

When buying trade scales the owner is necessarily given the accompanying documentation, which specifies a certain periodicity of weight checks.

Setting up the floor scales

Many women know firsthand the problem when trying to lose weight you exhaust yourself with intensive exercises for several days, when you don’t eat after 6 pm, when you refuse from a variety of delicious food and count calories, and the scales show weight gain.

After disappointment, most users of electronic equipment begin to doubt the accuracy of weighing results and look for a way to adjust the electronic floor scales.

But did the equipment settings really go astray, or simply your efforts did not bring the desired result?

How to test the scales for accuracy?

Floor weighing equipment has its own specifications and their lower weighing limit is usually at least 5-7 kg.

Therefore, you should not try to check the accuracy of the device with dumbbells, barbell pancakes or three-liter cans filled with water.

The devices are designed to determine the weight of a person, which means that all weighings with a different type of weight distribution on the platform may provoke inaccuracies in the results.

To check the accuracy of a household appliance, weigh yourself several times and record the results. For optimum results do not do less than 5 weighings.

After performing a series of weighings, calculate the difference between the highest and lowest weights obtained.

In this way you obtain a measurement error not exceeding 0.4 kg.

If your value is higher than this figure, you can conclude that the accuracy of the scales is impaired due to faulty sensors. You can replace the sensors in the service center.

Some models of weighing equipment involve the possibility of self-adjustment in two steps:

In this article we have shared with you recommendations on how to set up an electronic scale, and sincerely hope that the results of your weighing will be as correct as possible.

How to choose electronic floor scales, how to adjust, weigh and repair video

Controlling body weight is one of the keys to maintaining health and longevity. Knowing your own weight is important for dieting as well as for sports or health fitness.

Therefore, it is difficult to overestimate the degree of accuracy of this most important instrument, as well as its durability.

How to choose electronic floor scales, how to tune, how to weigh properly? What are the possible malfunctions and how to fix the floor scales with your own hands?

What weighing tools are available, how are they arranged

The most ancient scales are considered to be the samples found by archeologists in Mesopotamia and dated by the V century B.C.

They had a lever structure. two equal arms, each arm had a cup on it. With the advent of technological progress scales underwent many modifications.

To date, there are four main types of devices to determine the mass, different in principle:

  • Lever scales. based on the lever principle described by Archimedes;
  • spring- the principle of operation is described by Hooke’s law;
  • hydrostatic. measuring the specific weight (density) of a substance;
  • strain gauges. the measuring device in them is a sensor that converts deformation into electrical impulses.

In everyday life, predominantly spring (mechanical) and electronic (strain gauge) scales are used. We will talk about them below.


Mechanical scales are well known to everyone, they are based on the spring that stretches or compresses according to the force applied to it.

In mechanical scales, the hand is deflected by the action of a spring

When you weigh on a mechanical scale, you stand on a movable platform which is lowered by the weight of your body. The spring is compressed and the hand connected to it deflects to indicate the weight.


The electronic scale looks like a monolithic body resting on four supporting legs and equipped with a digital display for displaying weight and a battery-operated power supply.

Electronic scales have a high contrast screen and are easy to read

Electronic scale has no moving or rubbing parts and offers high accuracy of 100-300g.

Thanks to modern materials, a wide variety of designs are available.

Electronic circuitry expands the possibilities of scales: the device gets the memory of measurements, and can make simple calculations, including the display of body mass index (BMI).

How to choose a floor scale

Choosing the scale starts with determining what tasks will be entrusted to it. Many modern electronic scales are equipped with a variety of measuring functions that are designed to improve the quality of “service. Of course, their number is reflected in the price.

The main characteristics of the scales are:

The limit value of the mass, which scales can measure, ranging from 130 to 180 kg. Some models have higher values, this can be found in the technical passport of the product. It is important to choose the range within which the upper level of permitted loads will not be exceeded, since it leads to a rapid failure of the measuring mechanism.

The margin of error for determining weight is usually built-in and complies with generally accepted standards (100-300 grams). Some models have an adjustment function, which allows you to adjust the degree of deviation of the actual weight from the indicators on the display.

Computer technology does not stand still. the ability to process weighing information has increased significantly. Thus, the latest generation of floor scales can memorize the number of users and perform simple diagnostics: determine the percentage of fat and muscle mass, calculate BMI.

The powerful microprocessors with large memory capacity used in scales are capable of automatically identifying up to 10 people by memorizing their characteristics. The programs, with which such devices are equipped, are designed for universal use and require initial input of data about the height, age, and sex of the user.

For such an “examination,” the user must weigh in minimal clothing and with bare legs. It is through the soles of the feet that weak pulses of electric current enter the body. by the level of the response signal, the microcontroller determines the composition of the tissues.

For those who suffer from obesity it is useful to know the amount of visceral fat surrounding the internal organs of the abdomen. The method is based on the difference in electrical resistance of the tested tissues and allows identifying excess (or underweight) body weight.

Accuracy of the method is low and corresponds to “household” level diagnostics.

Besides, one should pay attention to such trivial things as the size of the information screen, the possibility of its illumination in the dark time of the day, etc. д. Important role played by the design, size and weight of the device. All this is meant to ensure the comfort and convenience of the device.

To choose an electronic scale that has the necessary functionality, it will help to carefully study the technical specifications reflected in the user manual.

Rating of best models

In order to navigate when choosing electronic scales, it is useful to study the rating data. The table represents two categories of scales: diagnostic and ordinary (non-diagnostic).

How to use and weigh correctly to get accurate readings

For reliable body weight measurements, you need to follow certain rules for using the scales.

How to use the floor scales correctly

After installation and adjustment of the scales it is important to follow the rules of operation recommended by the manufacturer in technical documentation. They include safety measures, peculiarities of connection and use of the device, as well as maintenance and cleaning procedures.

Place the device on a smooth rigid surface without bumps or holes. It is desirable that it is one permanent place where the data will have a minimum different error of measurement.

Correct weighing is ensured by observing the following conditions:

  • absence of unnecessary heavy clothing and additional accessories;
  • straight upright posture with arms down;
  • Do not make excessive sudden movements;
  • the placement of the legs symmetrically on both sides of the surface.

Handle with care to prolong the life of the device. ordinary electronic scales for a person can withstand the weight up to 220 kg. Exceeding these limits will result in damage to the mechanism. The structure of the device may also break as a result of a shock or water ingress.

Attention should be paid to the integrity of the body and protect it from external influences of extraneous factors:

  • temperature extremes, high humidity;
  • the proximity of heaters and batteries;
  • prolonged exposure to direct sunlight;
  • ingress of dust and other foreign substances.

Only damp or dry cloth can be used for cleaning the surface of the scale. It should not be cleaned under running water or with harsh detergents.

If you follow all the rules of storage and operation the device will have a long life and provide the most accurate measurements. The information obtained with the help of an electronic floor scale will allow you to control any changes in your figure and keep your body in a healthy shape.

Calibration methods

Important! Floor electronic scales can only be calibrated externally.

What you use the scale for

What you need the scales for: to calculate the price of weight products, packaged products, recalculate the quantity of piece goods, portion portioning, printing labels with weight and price. The answer determines which modes you need.

The classical set for commercial scales: weighing, price calculation, tare (tare weight resetting), often there is summing of the results, often the calculation of change.

Dosing, counting functions are not available on all models. And change control, available in many scales, is in fact almost never used by vendors.

When hotkeys and price memory are useful

You probably have some of your best-selling items. To serve customers faster, the price of these top items can be “stored” in the scales memory and called at the touch of a button. Typically, scales with a standard keyboard supports recall of 30-100 positions.

Models with connected barcode scanner and uploading to the accounting system can store data on hundreds and thousands of items.

For self-service stores there are special scales with large buttons, on which names/digits of products are written or food itself (usually fruits and vegetables). They immediately print a label with a barcode so that the customer can see the weight and price, and at the cash register he can pay for the selected item.

A label printing function

Special scales with label printer help you weigh the goods and print a label for it with price, name, weight per kilogram, composition and other information for the buyer.

These models are more expensive than a simple retail scale.

Scales with label printing are in demand in grocery stores, meat, fish, sweets, delicacies, nuts, ready meals, as well as in catering establishments where weighted portioned products are offered to guests.

How to tune the trading scales?

the principle of the calibration of the weighing equipment may differ slightly, depending on its functionality and variety. If you wonder how to configure the scales of the table type for trade, this procedure is carried out according to a fairly simple algorithm:

  • On the built-in remote control press a special button, which will put the electronics in the appropriate mode.
  • A specialized calibration weight is placed on the platform, which has a certain reference mass.
  • After a short period of time the weight is removed from the platform surface.

Важно! Установка точных значений массы на оборудовании определяется в автоматическом режиме. Данная процедура управляется за счет инсталлированного в электронное устройство программного обеспечения.

When buying trade scales the owner is necessarily given the accompanying documentation, which specifies a certain periodicity of checks of weight.

Важно! Недобросовестные продавцы могут настраивать электронные весы в свою пользу, обычно такая настройка производится за счет изначального программирования упаковочного веса. Поэтому отправляясь на рынок за продуктами, следует быть предельно внимательным и отдавать предпочтение крупным торговым центрам и супермаркетам, которые ценят собственную репутацию.

To calibrate your jewellery scales

Setting the accuracy of jewelry weighing instruments requires great care and attention. Let’s show the calibration procedure of the weighing instrument by the example of MH-500 jewelry scales.

  • Press and hold the “UNIT” button until the reading 500 appears on the display of the device.0. The device indicates the reference mass necessary for automatic calibration.
  • Press “UNIT” button to start the automatic calibration process. The word “CAL” flashes on the screen.
  • After the number 500 appears on the display again.0, carefully place the 500 gram weight on the centre of the instrument platform.
  • The device switches off automatically and then on again, the word “PASS” appears on the display. The calibration process is finished, the instrument is ready for weighing.

How to calibrate the electronic scale for clear and correct operation

If your electronic assistant still needs to adjust the settings, do so according to the manufacturer’s recommendations. You can imagine the calibration process step by step as follows:

  • Place the device on a perfectly flat surface, without level differences.
  • Turn the scales on. the On/Off button (On/Off), the display will show the reference point. 0,0 or 0,00.
  • Check that the chosen units are correct. depending on your needs they may be grams, ounces, or bars. Press the MODE button to make the selection.
  • Select MODE key (can be UNIT), and press it for at least 3 seconds., Wait until the abbreviation CAL appears.
  • Use MODE again: the CAL signal will light intermittently and then change to a number, depending on the type of scales, i.e. 100, 200, 300, 500.
  • Place the calibration weight on the pallet, the word “PASS” will appear on the display and the scale will switch to the “Weighing” option by itself.
  • Remove the weight from the scale and turn it off. That’s it, the calibration of the Chinese weigher is done.

Sensible approach to exploitation and careful attitude to scales will give you a long and reliable service, and properly performed calibration will provide maximum accuracy of the result.

Adjustment process

Before you decide to set up your electronic floor scale, you should insert the battery and test the device. This will allow you to find out information about the serviceability even in the store.

The basic settings include several major steps:

  • Floor scales should be placed only on a perfectly flat surface in a strictly horizontal position. It is best to use a floor that has a smooth texture. In no case do not fit carpets, uneven surfaces, protruding elements. They can increase the error of measurement.
  • If you do not know how to check the electronic scales, the first thing to do is to turn them on and run. This is done with a button or by touching the surface of the sensor. After that the zero countdown is displayed and it indicates that the device is ready for use. Some models can be switched on while weighing. Check the data sheet for the method. All the data is displayed there.
  • The Scarlett scale works accurately only when a person is level and their feet are parallel to one another. This is to ensure that the weight is evenly distributed and accurate readings are displayed. Sensors are usually placed on two sides of the center. Keep in mind that the stability of the device at first startup will subsequently affect the correctness of measurement readings. A huge number of models are automatically adjusted during the first start-up.

IMPORTANT! If there are any additional functions, it is better to learn about the peculiarities of adjustment in the manual. After all the procedures, you should have no questions about how to adjust the scales.

Experts told why we can weigh less in the morning than in the afternoon

Have you ever noticed that your daily weight can fluctuate within quite a wide range both in the direction of increase and decrease?? To put on a pound or two in 24 hours. is it possible?? Maybe it’s time for a change of scales? Don’t rush to spend money, everything is fine, the experts assure us, and now they will tell you why it happens.

Whether you are trying to lose or gain weight, or maybe you are satisfied with everything and want to stay in your current shape, weighing for people who care about their health and appearance is likely to be a ritual and an important daily routine that they can hardly imagine life without anymore. But even among the regular users of scales not everyone is aware that weighing accurately is not just “put both feet on the platform, read the number and go on with your business. It’s not just how you stand on the scale, but when you stand on it that matters for an accurate weight measurement!

The point is that, standing on the scale in the morning hours, you may notice that the weight will be somewhat less than it was the day before, say, in the evening. Many people have noticed this and said to themselves something like:

“I always weigh a little less in the morning than I do in the evening, but I can’t gain weight in 12 hours, right? Or is my body some kind of special? Maybe the scales are broken?”

We tried to find an explanation on the Net and this is what we found out by finding the reasoning of foreign doctors on the subject.

Biometric scales

A variety of home floor scales are distinguished by their electronic content. Models that determine the body’s biometric parameters, a set of resistors, microcircuits. The devices are no different from the simplest Chinese pink floor scales for teenage girls.

And biological parameters? The chip counts based on the a priori information entered by the user according to the manual. Mathematical operations are performed by the built-in controller, which collects readings of load cells. It is unnecessary to be afraid of floor scales, no matter how complex they may seem.

Avoid repairing home floor electronic scales that are under warranty. Not a washing machine, but expensive models, properly designed, are repaired by professionals.

Severe cases are handled by private firms. Restore the electronic scales functionality. Activities are accompanied by calibration. Another option for troubleshooting. Taring is a scientific word foreign to most citizens’ ears. The meaning of the process is limited to the correlation of the physical state of the sensor with the numbers.

The coming age of microcontrollers makes it hypothetically possible for ordinary citizens to create smart devices. The unique information of the Internet broadens the horizons, helping to master unfamiliar professions. Algorithm programming requires a special kind of mind. You can practice anywhere: the store, the logistics of your own movements, calculating mentally. Professionals prevent outside interference. The basics of science are handed down to a small circle of people. Internet helps change outdated traditions.
