1. Display Instrument not operating, monitor not working.

Reasons: Power cord is pulled out or no electric power input;malfunction of stabilized power source; safety fuse blew out.

Solutions: check the power lines and output voltage, connect the power supply.

2. Weight Value doesn’t change.

Reason: Weight Sensor cable failure; Weight Sensor damaged or Zero and Full Scale Calibration are incorrect.

Solutions: find the break point of the cable, reconnect it according to its color and take water-proof measures; or replace the sensor and recalibrate the Weight Zero and Weight Full Scale.

3.Upon receiving the signal, the displayed values change accordingly but in big discrepancy with the actual values and beyond the range of permissible error.

Reasons: Incorrect Calibration of Zero and Full Scale.

Solutions: re-calibrate the Weight Zero and Weight Full Scale.
