How to do calibration of electronic balance electronic bench scales

Generally, calibration gauges will be calibrated with higher precision gauges. Electronic balances, for example, need to be calibrated with weights or gauge blocks that are one level higher in accuracy than this balance.

Method: Press the cal button when the display appears cal-, that is, let go, and the display will appear cal-100, where "100" is a flashing code, indicating that a standard weight of 100g is required for calibrating the weight. At this point, the prepared "100g" calibration weight is placed on the weighing pan and the display appears"---"Wait for the state, after a long period of time, the display appears, take the calibration weight, the display should appear, if it is not zero, then clear, and repeat the above calibration operation.

Note: In order to get accurate calibration results, it is best to repeat the above calibration procedure twice. ）

The general process is: boot up, preheat, adjust the level, put the calibration weight, and calibrate the calibration.

The calibration method of electronic scale is as follows:

1. Turn on the switch of the electronic scale, and press and hold the decimal point in the right panel.

2. Press the 8 key in the panel when center appears, and 150000 will appear in the single column, you can ignore this step and press the accumulation key in the panel to enter the next step.

4. At this time, there will be a weight value, you see how many grams of weight in your hand, you will enter how much weight, for example, there are 2000g weights, I have to enter 20000, enter one more 0 is for the decimal point, there is no decimal point; Press the Accumulate button to proceed to the next step.

5. At this time, LCP will appear in the weight column of the electronic scale screen, and ON will appear in the single weight column.

6. Press in the panel'Cumulative'to proceed to the next step, ignore the ** that appears, and press the accumulation key.

7. The weight column will appear cal, the single weight column will appear 0, the total number of weights will appear in the column, prepare the weights, press the accumulation key to enter the next step.

8. Put the weight, wait for a few seconds, the electronic scale will automatically correct, when the weight of the weight appears in the weight column, it means that the weight correction is completed.

Turn on the electronic scale to zero first, and then press and hold the buckle weight button after returning to zero.

After reading the zero point, the weight appears, and you can see that the display is the number 1000 on it, which is one kilogram.

Take a kilogram of weight and put it in the middle of the scale, read it and take it off, so that the calibration is complete.

You can calibrate according to the instructions of the electronic scale, or you can find a professional maintenance technician for calibration. Zhengzhou Jinmai weighing instrument electronic scale experts to serve you.

How to calibrate the electronic scale and how to calibrate the electronic scale.

Calibration method of electric rotten Luzi bench scaleHello dear, electronic bench scale calibration method: 1. Check whether the internal calibration electronic platform scale, whether the appearance is clean, whether the electronic scale switch is in good condition, whether the power is sufficient, and whether the display is bright, complete and clear. 2. Whether the zero position of the electronic platform scale is correct.

3. Use standard cavity weights of different qualities (the weight is within the range of the electronic platform scale) to measure the weight in turn and record the stable reading. (Substitution method is allowed three times) 4, take the standard weight of the electronic platform scale 1 3 range load, calibrate at the four corners of the electronic platform scale, and the center point, and record the reading after each stabilization. 5. Calibration of electronic platform scale repeatability mis-renting

Take the weight of the maximum load (full scale) of the electronic bench scale, place it in the center of the electronic bench weighing pan four times, and record the reading after each stabilization. I hope it can help you.

The method of electronic scale calibration: first press and hold the ". . . " on the keyboardbutton, do not release until centr is displayed, release the button, then press the "8" key, and then click the "Accumulation" button, then the weight bar will display:

d1, single weight column display: 2 (numbers may be different); The number displayed in the single column represents the accuracy of the scale, if 2 is displayed, the accuracy is, and then press the "Total" button, the single column displays a very small number, then the electronic platform scale will be restored to factory settings, and then click the "Total" button again, use the weight and the number entered to correct Fushen, then the electronic scale will be corrected successfully.

The method of adjusting the unit price of the electronic platform scale: first start the electronic scale, and then press the storage button, then the electronic platform scale will only display the number under the unit price option, and then enter the unit price of the commodity, the unit price will be stored in the machine, it should be noted that the price of the single beam hall here is per kilogram, which is what we usually say 2 catties.

Electronic bench scale: It is a weighing instrument that uses the principle of force deformation of electronic strain rubber element to output a small analog electrical signal, and transmits it to the weighing display instrument through the signal cable to carry out weighing operation and display the weighing results. Boot automatic zero, can be manually tare zero, AC DC power supply, digital display of weighing data, can also add weight accumulation function, counting function, checkweighing and sorting function, dynamic weighing function and so on.

1.The illegal calibration of electronic scales is carried out using the allowable range of the standard weight mass value and the calibration code value of the calibration program, because the calibration code value has a certain spatial range (for example, the electronic scale with a maximum weight of 150kg, its 50kg inner code value is in the range of 12000 18000, and it can be calibrated to 50kg display value. If the actual weight of the calibration weight is 49 kg and the calibration display value is 50 kg, then the actual weight when the scale shows 150 kg is 147 kg.

It is self-evident what consequences this size will have in market trading. This is legal measurement in the national economy.

in importance. 2.After installation, check whether the connection of all parts of the scale body is good, and the scale body must not be in contact with any part of the foundation.

The distance between the scale body and the surrounding edge protection is 10 mm to 15 mm. 3.Before commissioning, turn on the power switch to warm up for 15 minutes, and try to use a vehicle with a load close to the maximum weight, repeatedly pass back and forth and stop on the load-bearing platform, using a torque wrench.

Tighten each load cell.

of high-strength bolts. 4.The output voltage of each load cell is measured sequentially with a digital voltmeter. If there are inconsistencies, adjust the junction box.

in two precision adjustable resistors to reduce the difference between them. However, the amount of adjustment must be noted with two adjustable resistors.

It should be rotated in the same direction and amount. When rotated clockwise, the resistance decreases, the output voltage increases, and the displayed value increases, and vice versa. until the output of all load cells is consistent.

5.Generally, the gravimetric method can be used for debugging, that is, the 1 10 of the maximum weighing weight is placed on the center of the load-bearing table and the load-bearing table above each load cell in turn, and the difference of each load cell output is accurately measured by the true difference method. At the same time, the two precision adjustable resistors corresponding to each load cell are adjusted separately to reduce the difference, but the direction of rotation and the amount of rotation are the same.

6.After the key points are debugged, a weight equivalent to the maximum weight is evenly added to the load-bearing platform. After following the position and method described in the manual of each weighing indicator, the displayed value is consistent with the weight value, remove the weight, and confirm that the empty scale shows "0".

7.Finally, the maximum weight is divided into several parts, including the minimum weight, the maximum weight, and the tolerance of change for each weighing point. The weighing error of each point is required to be no greater than the maximum tolerance requirement for each weighing point.

In the number setting area on the right side of the scale, hold down the decimal point for a few seconds, and release it when "centr" appears.

Then press the "8" key, and 75000 will appear in the single column. You can ignore this step and press the "Accumulation" key to enter the next step.

This is when the weight value appears, and this step is more important. Enter the weight of as many weights as you have in your hand, and remember to reserve the number of decimal places. For example, if I have a 5,000g weight, I have to enter 50,000 because there is a 0 for the decimal point.

If you only enter 5000, only 5000 will be displayed after the correction is completed, with no decimal point. After entering, press the "Accumulation" button to proceed to the next step.

At this time, the weight column of the electronic scale will appear: LCP, and the single weight column will appear: OFF.

Put the weights on and wait a few seconds for the scale to automatically adjust. When the weight bar jumps to the weight weight, the correction is complete.
