After the sensor is crushed, the following phenomena may occur: 1. Inaccurate weighing; 2. Display does not reset to zero; 3. The displayed numbers fluctuate randomly.
To diagnose the floor scale sensors:
1. First, use the resistance setting to measure the resistance between each pair of the four wires, resulting in six combinations. If the resistance is 400-450 ohms, it indicates +E-E; if 350 ohms, then +S-S; if 290 ohms, it represents the R bridge arm.
2. Connect +E-E terminals to ±_5V voltage. Correctly apply a pressure to the floor scale sensor. If the output ±_S increases, the red probe corresponds to +S; otherwise, it's -S.
