How to quickly calibrate electronic scales

February 11, 2024

Everyone knows that the accuracy of weighing electronic scales is quite high. Generally, we will adjust electronic scales according to the requirements of users before shipping. Isn't it our electronic scale that doesn't need to be debugged? This is not the case. Although the manufacturers have helped us to debug, it will inevitably not be bumped in the process of transportation, and it may lead to the weighing of electronic scales. After we receive the electronic scales installed, we must check whether the connection of each part of the electronic scales is in good condition. The electronic scales should not be in contact with any part of the foundation. The distance between the electronic scales and the surrounding iron is 10mm-15mm.

The following Xiao Bian came to talk about the rapid calibration method of electronic scales:

1. After the electronic and electronic scales are properly adjusted, the weight equivalent to the maximum weight is evenly added to the electronic scale weighing platform, and the displayed values ​​are displayed according to the positions and methods described in the specifications of the various weighing indicators. After agreeing with the weight value, remove the weight and confirm that the empty scale shows “0”. Finally, the maximum weighing capacity is divided into several parts, including the weighing scale's minimum, maximum weighing capacity, and various weighing points where the tolerance changes. The weighing error at each point of the electronic scale is not greater than the maximum tolerance of each weighing point. Claim.

2. Use a digital voltmeter to measure the output voltage of each load cell in electronic scales in order. If there is inconsistency, adjust the corresponding two precision adjustable resistors in the junction box to reduce the difference between them. However, the amount of adjustment must be noted that the two adjustable resistors must be rotated in the same direction and the same amount of rotation should be used. When turning clockwise, the resistance decreases, the output voltage increases, and the displayed value increases. Otherwise, the opposite is true. Until the adjustment to the electronic scales, the output of each weighing sensor is the same.

Debugging is generally carried out using the gravimetric method, which means that the weights of the 1/10 largest scales are successively placed on the center position of the electronic scale weighing platform and on the weighing platform above each weighing sensor, and the actual difference method is used to measure each weight accurately. The amount of difference in the output of the load cell is adjusted, and the corresponding two precision adjustable resistances of the weighing scales of the electronic scales are respectively adjusted to reduce the amount of difference between them, but the rotation direction and the rotation amount are also the same.

3. Refer to the instruction manual of the electronic and electronic scale weighing indicator to check the correctness of various function keys and improve the weighing accuracy of electronic scales.
