If both are good feeder

　　We can basically judge whether it is good or not. Generally, if the sensor fails to work, there will be problems with the weighing data. At this time, it is easy to use the substitution method to try it, which is fast.

　　Take down the sensor, test the resistance with the meter, and the weighbridge load cell is the same as the common load cell. It is convenient to test and judge whether it is good or not: when the wiring is disconnected, measure the resistance between the two lines of the power supply with the multimeter resistance gear (generally red and black) to see whether it is 760 Ω; measure the resistance between the two lines of the output signal (generally green and white) to see whether it is 700 Ω. If both are good, if one is not, it is bad. I hope it can help you.
