The repair methods in different situations of belt weigh scale.

1. the linear differential of a measuring system
You can check the characteristics of the sensor,whether damage due to overloading or improper use conditions.

2. when zeroing empty belt,instantaneous table indicates fluctuations is big
May be caused by fluctuations of the belt itself,generally require control within + -5%,too much will effect the measurement accuracy.

3. After parts replacement,belt weigh scale can not reach the using precision,after parts replacement it should be re-matched with belt weigh scale calibration.

4. dynamic zero changes largely every day
It may be the belt's problem;it also may be in the calibration,the predetermined time of sensor is not enough.It should be generally do zero testing in the running belt 15min dynamic.

5. After a period of use,when the empty belt run,the instantaneous indication of the meter becomes larger, it should check the belt itself and each group of idler in measurement segment  checked and is rotating flexible or not,runout exceeds the allowable value.

6. the dynamic zero changes larger before and after the delivery of materials
Probably the hardness of belt changes before and after the delivery of materials,and make the belt tension changes.It can set the dynamic zero value in the middle of the before and after the two zeros on the transport of materials.

7. The measuring system of belt weigh scale is working properly,but the low-precision measuring apparatus which may be allowed when the calibration.Calibration of apparatus shall be approved prior to the calibration line test,meet the standard can be used.

8. the reproducibility of hanging code calibration is poor
The main problem is in the installation,you can check whether the fixed frame scales smooth,tighten the nut is tightened,and the hanging bracket code is loose.

9. hanging code calibration,the instrument response is not obvious or no response after adding weight
Probably limit the scale frame bracket or the force sensor is very small,it may be voltage is not enough supply  to the bridge.

10.empty belt adjustment operation is less than zero
The main changes are the sensor initial zero or zero potential cause abnormal.

11.after running for some time belt scale is not allowed
After the maintenance of belt weigh scale due to certain changes in conditions,such as tension,shock force,deviation,etc.this time should be re-calibrated by the line and find a new correction factor.
