Q. How to know whether the weighing sensors are damaged or not

A. 1. Use a digital multimeter to measure impedanceIf the resistance of bridge arm for one sensor is 350Ω, then the measured input/output impedance by a digital multimeter should be 350Ω. If not, it should be deemed to be damaged.

2. Zero Detection
Normally, the working voltage for a sensor is 5~12V DC.
