The phenomenon of data drift and instability of digital truck scale is mainly caused by power grounding and sensor output instability. Press the test button to check the weight code output by the sensor to determine what is the cause.
If you press the test button and find that the signals output by all digital sensors are unstable, it can be judged that the power ground wire is charged. At this time, the ground wire needs to be repaired. Check the weight code output by the sensor through the test button, and find that only the No. 1 sensor The code value of 1 jumps very greatly, and the signals of other digital sensors are very stable. It is judged that the No. 1 sensor is damaged. After replacing the No. 1 sensor, the instrument works normally.
