How to calibrate Chinese kitchen scales

Repairing kitchen electronic scales with your own hands, calibration.

In many industries, the correctness of weighing is an important indicator. But the scales can from time to time get out of normal and accurate operation. To carry out prevention or eliminate problems, it is necessary to periodically adjust.

This is called calibration. Many are faced with the need to conduct it and want to know the answer to the question: “How can you calibrate electronic floor scales with your own hands”.

How to use kitchen electronic weights?

Using electronic scales for the kitchen is very simple:

  • Insert the batteries and turn on the scales on/off button. The symbol “0” will light up on the screen.
  • Determine the units of measurement: kg/pounds or g/ounce, depends on the model. The mechanism will remember your choice.
  • If you weigh the product in a plate, put an empty container on the scales and press the TARE button. Its heaviness will be dug up, and the weight of the clean product will be shown.
  • Put the weighed item exactly in the center of the platform.
  • A lot of product will appear on the display.
  • Having finished, turn off the scales. If you forget, in a few minutes they will turn off themselves.

In many industries, the correctness of weighing is an important indicator. But the scales can from time to time get out of normal and accurate operation. To carry out prevention or eliminate problems, it is necessary to periodically adjust.

This is called calibration. Many are faced with the need to conduct it and want to know the answer to the question: “How can you calibrate electronic floor scales with your own hands”.

Calibration methods

Important! The calibration of floor electronic scales is produced only by the external method.

Repair of electronic scales | An electrician

Electronic weights, after prolonged use, also can fail. Although floor electronic weights are a simple electronic device and with a small number of electronic elements, to detect a breakdown and repair of the device, you will have to spend a little time.

If your electronic weights do not show any signs of life at all, first you need to try to change the battery, as a rule, they eat from the battery type “tablet” for 3 voltes, and do not test the scales with a battery from another device, the scales are needed exclusively fresh and with a stable a voltage of 3 volts of a battery, otherwise some devices are already when a voltage is reduced to 2.8Volta may not be “launched”. So if we are convinced that the device does not work with the new battery, we need to disassemble and inspect its insides.

After we untwisted all the screws and removed the lid, we need to inspect all visible and affordable connections and installation of radio elements, as well as the integrity of all details. It often happens that during operation, the wiring entering the board is laid out, or it is, as it were, in its place but already from rot, you need to gently try the reliability of their connection.

Found divorced wiring must be soldered back, and the damaged tracks are restored. The place of the defect is protected, degreased and tinned, the jumper or a large drop of solder attacks on top. It is advisable to cover the ration of the soldering with special varnish or just nail polish.

Displays in such scales are liquid crystallines as a rule and are connected to the board either using a loop, or using a multi.pine.conducting “elastic band”. It often happens that the gum does not adjoin the display board or glass, in such cases, the image on the display wakes up or incomplete. In such cases, it is necessary to rinse the elastic band and contacts of the board with alcohol, install in place and make sure of the reliability of the screws fixing the fee, if there is a suspicion of insufficient “tightening” or disruption of thread for the screw, you need to squeeze the board to the elastic band by any means, for this, for example, you can put a small A bar of foamy materials such as foam between the board and the back cover or will fade to restore the density of the thread using the glue “Moment”.

All electronic scales have a maximum weight that should not exceed. When exceeding, as a rule, more than 150-180 kg can bend the power elements of the frame structure. Of course, they can be fed, but such a “repair” will clearly affect the previous accuracy of weight measurements.

In addition, when adding weight, a breakdown of one or more measurement sensors may occur, which are at four corners and are fixed on the power frame. The measurement sensor. an tensodel, can be checked using a tester, for this we solder all four sensors from the board and measure the resistance of the sensors.

Принципиальная схема мостового измерения сопротивления тензодатчиков

In the unloaded state, the resistance of all sensors should be approximately the same, if one of the sensors has large deviations of resistance, then it is clearly faulty.

It will foul it is very difficult to repair such a sensor since it is filled with a compound and easier to find four new tensodists or one sensor with identical resistance indicators from a similar scales model.

But if the new sensor cannot be found, you can try to carefully pick the glue (compound) inside is a copper.colored plate, to which three wiring is soldered, sometimes it happens that one of them is torn and sufficiently solder the wiring and the sensor will be restored.

  • If the scales show only zero, regardless of loading, then either the tensodel is out of order, or the break in the circuit from the sensor to the ADC.
  • If the scales do not show anything, then there may be a problem with power (battery) or a break from the board to the “power buttons” that are usually inside the power frame on two legs of the scales remotely remote from the display.

It often happens that weights fail due to dust and fine debris in them, as well as the emergency operation of them in a humid environment. It will be enough in such cases to clean the fee and radio.element and dry all the weights.

Calibration of electronic weights

Sometimes there is a need to calibrate weights when replacing tensodists or improper calibration, for example, when weights are very good. To do this, click on the button of their power and hold it until you see “CAL” on the board. Then the digital value of the mass will appear, with the help of it a calibration will be made. As a standard, you can apply any item of the weight that you know. Put it on the scales and after a few minutes “PASS” will appear on the display, then you will need to remove this inscription, turn off the scales, and then turn them on again. Elekt.Blogspot.com

Periodicity

The instruction includes several points:

calibrate, chinese, kitchen, scales
  • Install the device on a flat work surface;
  • Turn on;
  • Using “Mode” or “Unit”, to choose when “CAL” blows on the monitor;
  • Click on “Mode” /”Unit” again;
  • Put the standard on the platform;
  • “Pass” will appear;
  • At the end of the process, the transition to the work takes place independently;
  • Remove the load from the platform.

The method is also used in order to rate floor electronic scales. There is another way to calibrate the scales.

  • Click on “1” and go to the calibration menu;
  • Click on “T”;
  • When “2” is displayed, then we put the load on the platform half of the possible for the device;
  • The program will show numbers from 1 to 10, as they appear on these keys, you will need to press;
  • Remove the load.

Basically, when buying devices, they do not give any standards, so in this case it is necessary to use the internal method. This function is in modern devices.

  • Enter a number on the display, which is 1/3 from the maximum possible and click “T”;
  • Indicate the calibration mass in grams
  • Press “T”;
  • We gain the maximum value;
  • Confirm the procedure of the “T” key;
  • We gain a number from 1 to 10, which indicates the number of signs after aim.

People engaged in trade are interested in how to calibrate electronic scales.

To set up models with a cost counter:

Fix a digital scale which needs calibration

  • Keep the code, it can be recognized in the instructions or in the passport;
  • We use the “Tara” button, and then “1” and again “Tara”;
  • On the price indicator, “2” appears, and a dash is displayed on the screen, here you need to install a load corresponding to half the permissible value;
  • We put the product of the mass that was introduced before and press on “T”;
  • On the indicator of the value of the price, the number “3” will appear;
  • We drive a value in kg and click on “T”;
  • When “4” appears, we collect the most allowable mass and click “T”;
  • “5” lights up, after which it is a sampling coefficient, which varies from 1 to 10, 10 sets in the default settings and confirm the “T” key;
  • When “6” appears, we enter the sampling parameter again and click on “t”.

Calibration of electronic scales independently for CAS models is carried out in this way:

  • Remove the seal and cover;
  • Translate the lever built into them in another position;
  • After the “CAL” lights up and blinks 3 times to press “3”, thereby starting the tariffing mode;
  • The word “uload” appears;
  • Click on “C” and wait for “Load”;
  • We put on a working surface alternately weights for calibration, weighing 6 kg, 15 kg, 30 kg and press on “C”;
  • After the appearance of the “END”, we press on “C”, and then on “0”;
  • Turn off, CAS weight calibration is completed.

Midl Libra calibration is made according to this algorithm:

  • Remove the lid and install two switches for tariffing;
  • After self.testing will be “0” and the factory model code will be displayed;
  • After choosing the largest limit, we press on the ITG button, and then “0”,
  • To do this, click “P”, and then “SBR” and confirm the choice of “NPV”;
  • Then click “ITG”, and after “6”, it will show the number 24000, and the ratio of discreteness and the range will be displayed on the indicator indicator;
  • Press the buttons “T” and “C” alternately;
  • We put the weights for calibration weighing at least 1/3 of the maximum allowable for this model and click on ITG, and then “7” and take the weight values ​​that were put on the scales platform and click “SBR”;
  • After all the operations, we click “ITG”;
  • We leave the calibration regulation, removing two jumpers;
  • Cover the device, seal the seal, calibration of the midwives is over.

Important! Libra calibration should only be done when stable indicators are reached on the device display.

Many industries use Baurer brand devices. Their targeting is very simple, for this it is necessary to enter the settings, set the indicators, launch into the work.

Checking the accuracy of car weights is carried out when there is no indicator with the standard, also the rating of the scales can be performed planned with the frequency specified in the passport. In automobile scales, calibration is carried out through software equipment. Access to it is limited to avoid setting up irregular indicators.

Jewelry electronic scales requires special accuracy and accuracy when conducting independent calibration of indicators.

  • Turn on using Power;
  • Click “Units” and wait for the appearance of the inscription “CAL”;
  • Click “Units” and bed on the working platform the necessary weights for calibration;
  • The word “pass” will be displayed and the scales will independently go into the weighing mode;
  • Remove the standard and turn off the device.

Libra calibration is an important process in their maintenance. Without this, the exact work is very difficult to guarantee. In order to perform this process, it is not necessary to contact the help of unauthorized persons or organizations. This is necessary only for complex models in some industries subject to the control of the metrological service.

The adjustment of the scales in the right direction is very easy to do independently and does not require any special knowledge, but only follow the instructions in the instructions. But with doubt that the process is done correctly to the nearest metrological center.

China weighing scale calibration

Calibration methods

The accuracy of measuring the device can be lost both in the process of operation and with simple movement from one place to another. How to calibrate scales yourself? There are several ways.

  • External. For such calibration, a special weight is used, called the standard. External calibration is used for both electronic and mechanical weights.

Calibration of floor mechanical weights, like all mechanical measuring instruments, is produced only in the external way when using special weights.

Violation of the performance of the sensor

A tensodel is a component that is responsible for converting the value of deformation into the signal that the human eye is used to seeing on the display. The use of such details is very convenient for the accuracy of measuring weight.

Important! All the changes that are fixed by this device are so small that they will not be able to fix them. The main work in this design is performed by a special plate in size within 2 cm. It is this plate that “collects” data from each of the corners of electronic scales, is engaged in their processing and transfer to another block. for the output to the monitor.

In other words, a tensodel is a piece of iron that can only be damaged by mechanical exposure, which is a very difficult task. In order to conduct diagnostics, a special electric tester will be required.

Also, a malfunction in the work of the scales can occur due to the wiring, which goes to this very sensor. Here everything can be corrected with a conventional soldering iron, and if the sensor is completely broken, then he will have to look for a replacement.

Important! Pay more attention to the choice of a new component, since it must have the same technical parameters. If the parameters do not correspond to the model, you risk obtaining inaccuracy in the measurement of weight.

Options for calibration of Chinese weights

To calibrate trading scales, you need to enter the settings mode. On models equipped with a jump, the launch of the calibration mode is initiated by switching the toggle switch. Devices without such an option are converted into settings by entering digital code. The desired combination should be searched in the documentation for the device or on the network by the name of the model.

Setting up models with a cost meter

  • Open the calibration menu input of the digital code and by pressing the “1” button.
  • Launch the mode of setting weights to the zero indicator by pressing the “T” button (Tara).
  • The appearance of the number “2” on the “price” indicator signals the readiness of the device for the installation of a weight of the reference mass, equal to half the maximum possible device for this model. You should set the desired weight and press the “T” button.
  • When the number “3” appears, enter the mass of the installed weight in kilograms and click the “T” button.
  • When the number “4” appears, enter the value of the maximum permissible mass of the cargo and slip “T”.
  • When the number “5” appears, enter the accuracy coefficient (from 1 to 10) and click “T”. You can use the default sampling value equal to 10.
  • The process of configuring the device is over, remove the weights.

Settings using the internal calibration mechanism

Libra equipped with a built.in program settings for the accuracy of weighing are calibrated according to the following algorithm.

  • After the transition to the settings mode, enter the value of the calibration weight equal to 1/3 of the maximum permissible and slip the “T” button. So, for a device designed for 300 kg of NPV, a third will be 100 kg.
  • Indicate the calibration mass in grams. To continue the process, click the “T” button.
  • Enter the value of the largest weighing limit in grams and confirm the “T” slippers.
  • Enter the sampling coefficient (from 2 to 10) and click the “T” button.
  • On the screen of the device, 100 should be highlighted with the indicated number of zeros after aim, which means the end of the process of calibration of the device.

How tuning is made

In most cases, instructions on how to calibrate electronic scales are contained in the user manual. Typically used technology associated with the use of reference weights. By pressing a special button on the control panel, the device translates the settings mode.

First of all, the “zero” setting is checked. with an empty platform, the display should show the zero mass. Next, the standard of the weight of the mass that is requested by the program is installed on the platform. In the absence of just such a weight, you can choose from the number of options proposed by the program of the weight that is at the disposal. At the same time, electronics remember the conditions for weighing the reference mass.

After exiting the setting mode, you can try to weigh the reference weight: the display will not necessarily show the perfectly accurate mass, but the deviations should be within the passport accuracy. Thus, the calibration of electronic weights is independently performed at two points. zero mass and mass of the reference weight.

Typically, any seller knows how to calibrate electronic scales. there is nothing complicated in this procedure. Only those who do not have the necessary reference weights or when the owner of the store is not entirely sure of the experience and good faith of their sellers can contact a special service for its service.

After reading how to calibrate the electronic 40 kg of scales, you can find weights with a total weight of up to 10 kilograms, and to verify the device for weighing goods weighing up to one or two tons, quite heavy weights will be required, so it makes sense to call specialists who come with their set of standards.

How to choose kitchen electronic scales?

Following preferences, choose electronic scales for the kitchen according to the main criteria: functionality, quality and appearance. The requirements are connected and depend on each other: high.class technique made of steel has many opportunities, looks presentable and is able to last 10 years.

  • The case of a quality product covers the mechanism completely. Evaluate the thickness of the cracks and gaps.
  • Plastic parts reduce the price and shorten the service life, compared with metal and glass.
  • If you choose glass, then only hardened. Both for the case and for the bowl.
  • Tree. looks expensive, requires careful care.
  • Determine the shape of the scales with your needs. Different products are more convenient to weigh in their own way. Sometimes you need to really “enter” a new element into the kitchen.
  • Buttons. more convenient rubber. Plastic ones are short.lived, they can fall asleep and wipe the substrate.
  • Sensory management. convenient, modern. Does not tolerate wet hands.
  • Liquid crystal screen. with or without backlighting.
  • Maximum weight-an average of 3-5 kg. Professional withstand up to 20.
  • The smaller the division step, the more accurate the result. Best 1-2 g.
  • If desired, you can take a kitchen device with rich functionality. Equipped with a mini-computer, they can calculate the energy and nutritional value of even complex dishes for you.

Desktop electronic kitchen scales

When you already know how to choose electronic scales for the kitchen, determine the shape suitable for you. Focus on your needs: what are you planning to weigh more? The simplest and most common kitchen electronic scales are a desktop model with a thin flat platform. On a surface of a slightly smaller A4 sheet, large fruits and vegetables, long spaghetti, large pieces of meat and fish are placed. The apple can be weighed right on the platform. Chicken breast. in a plate, having previously rejected its value.

Kitchen electronic wall scales

If the selection of electronic weights for the kitchen involves the correspondence to a special interior, take a closer look at the options that are attached directly to the wall. They look mysterious for the uninitiated: such an incomprehensible display. The weighing surface is thrown back on top before use, and after that it rises to its place. Evaluation of convenience yourself. to remove and work with them on the table will not work.

Kitchen electronic scales

Another useful device, which is kitchen electronic scales for products and not only, has the shape of a conventional spoon. The size of a dining room, up to 25 cm long, functionally replaces ordinary electronic scales. There is a display, the choice of units of measure, a deduction of containers, auto shutdown and an overload indicator. Itself weighs 50 g, and the measurement limit is up to 500 g. And pharmaceutical accuracy. 0.1 g of errors. Use it for measuring:

  • spices;
  • drugs;
  • children’s mixtures;
  • protein cocktails;
  • herbal fees;
  • pet food;
  • wherever you need the accurate dosage.

Kitchen electronic scales with a bowl

Macarons, cereals, berries. for small bulk products, choose a model with a bowl, best removable. She is easy to wash, so feel free to knead even the dough in it. With the built.in zeroing function, you can measure each ingredient from the recipe without removing the previous one from the container. Such an opportunity is useful in confectionery art, requiring accuracy to a gram.

Of the materials is most suitable for the scales of the weights of kitchen electronic stainless steel. This is a strong, durable, inert alloy that does not respond with products, does not beat and withstands the procedures in the dishwasher. There are also beautiful bowls of plastic or glass. However, if the first is accidentally melted, and the second breaks, they will have to make replacement to order.

Kitchen electronic professional scales

Representing the best kitchen scales electronic mechanisms are used not only in stores and in restaurant kitchens. Professional households are capable of satisfying the needs of demanding housewives. They are distinguished from household electronic scales:

Electronic scales for the kitchen. rating

Each requirements for Libra have their own. Different manufacturers focus on reliability, advanced opportunities, design or savings. The rating of kitchen weights of electronic models will help to decide on the choice.

The procedure for calibration of jewelry weights

Setting up accuracy of weighing instruments of jewelry requires special accuracy and attentiveness. The procedure for calibrating the weighing tool we will show on the example of the MH-500 jewelry weights.

  • Click the UNIT key with holding, waiting for the appearance of 500 values ​​on the device display.0. The device indicates the standard mass necessary for automatic calibration.
  • Click the UNIT button to start the automatic settings process. The inscription “Cal” flickers on the screen.
  • After repeated numbers 500 on the display.0, neatly on the center of the platform of the device, set the weight by 500 grams.
  • The device will automatically turn off and turn on again, the word “pass” will appear on the screen. The calibration process is completed, the device is ready to weigh.

Libra is biometric

A variety of home floor scales distinguishes electronic filling. Models that determine the biometric parameters of the body, a set of resistors, microcircuits. Devices from the simplest Chinese pink floor scales for teenage girls are no different.

And biological parameters? Calculates the microcircuit, guided by a priori information introduced by the user in accordance with the leadership. Mathematical operations are conducted by a built.in controller collecting tensodic testers. It is unnecessary to be afraid of the floor scales, no matter how difficult they may seem.

Care and operation rules

For correct work, it is important not only to choose and use the device, but also to care for it with high quality. Performing a few tips to maintain the device, you will achieve a longer service life and accuracy when weighing:

  • Electronic scales, as you know, are extremely sensitive. Therefore, it is worth avoiding sharp changes in temperature, a large amount of moisture, sharp lowering or shaking, getting dirt and direct sunlight.
  • Do not bring scales to heating devices.
  • To clean the device, it is not recommended to use chemicals.
  • Avoid the entry of various fluids on the surface of the measuring unit.

Repairing kitchen electronic scales with your own hands, calibration.

Electronic kitchen scales are becoming increasingly popular for kitchen equipment. In the pursuit of healthy nutrition and the desire to lose weight, it is important for many to know the exact number of ingredients of the dish. Yes, it is just convenient when you need to accurately observe the ratio of ingredients in a new dish. N etho, a small useful device can sometimes fail. Then it is important to know how to quickly fix such scales yourself. Before carrying the scales for repairs, check, maybe you can fix them yourself. Or maybe you just need to change the battery or make calibration.

Possible breakdowns and ways to eliminate them

Often, if the scales went out and stopped showing numbers, this is due to the power supply. It works on batteries, therefore, in order to check the suitability, you need to carefully remove the weight body. Then remove the nutrition elements and check their work on another working device for which they are suitable. In 80 cases out of 100 scales, they stopped working due to the fact that they just sat down batteries. Replacing them on your own is easier.

Libra and display connects in most devices a train. Иногда он неплотно примыкает к деталям, из-за чего наблюдается неисправность в работе. To cope with the problem, you just need to raise the fee and press it tightly to the display. It is convenient to do this using a wooden bar. Install it between the board and the lower part of the case.

As statistics shows, such a problem arises due to the fact that the contact ends of the scales are thinner. It is important that the contact ends are tightly adjacent to the special legs of the scales. To fix the problem, you need to find a relay of the desired size and replace the contacts on it. Then attach wires to the contacts, and best of all, if there is such an opportunity, then solder.

Very often, kitchen scales stop working due to the fact that particles of food, bulk substances get inside. Kitchen electronic watches must be constantly cleaned inside. If, suddenly, water falls on the scales, you need to quickly wipe it with a clean towel. Also make sure that the scales show the exact weight, and the initial amount of weighing does not exceed the marginal norm.

How to carry out calibration?

A lot depends on the specific model, but the general scheme is the same. It is necessary to press the corresponding button (the instructions say what exactly) and hold it for about thirty seconds so that the inscription CAL appears on the display. Then the digital value of the mass should appear by which calibration is carried out. As a standard, you can choose any object on which there are accurate weight indicators. As soon as a few seconds pass, the word PASS will appear, indicating that the calibration is successfully completed. It remains only to delete the inscription and turn off the device.

Important! If the inscription Fail appeared, then the calibration was unsuccessful and the whole scheme must be repeated again.

These are the main malfunctions that arise with electronic kitchen weights, which are most often complained about housewives. Unlike more complex household appliances, the problems of this plan can be solved independently, without even resorting to the help of the husband, son.in.law or father. But, if no of the above methods helps to eliminate the cause, then we must stop amateur performances and contact specialists.

Electronic weights, after prolonged use, also can fail. Although floor electronic weights are a simple electronic device and with a small number of electronic elements, to detect a breakdown and repair of the device, you will have to spend a little time.

If your electronic weights do not show any signs of life at all, first you need to try to change the battery, as a rule they eat from the battery type “tablet” for 3 voltes, and you should not test the scales with a battery from another device, you need an exceptionally fresh and stable scales and a stable scales. a voltage of 3 volts of a battery, otherwise some devices are already when a voltage is reduced to 2.8Volt may not be “launched”. So if we are convinced that the device does not work with the new battery, we need to disassemble and inspect its insides.

After we untwisted all the screws and removed the lid, we need to inspect all visible and affordable connections and installation of radio elements, as well as the integrity of all details. It often happens that during operation, the wiring entering the board is laid out, or it is, as it were, in its place but already from rot, you need to gently try the reliability of their connection.

Found divorced wiring must be soldered back, and the damaged tracks are restored. The place of the defect is protected, degreased and tinned, the jumper or a large drop of solder attacks on top. It is advisable to cover the ration of the soldering with special varnish or just nail polish.
