Calibration Procedure:
The English display interface supports key-operated calibration and zeroing, with a no-weight calibration function. It is simple to operate, facilitating quick on-site configuration, debugging, and troubleshooting—eliminating the complexity of connecting to a host computer.

1. Select sensor settings. Password is 1111. Then select range calibration.
2. For weight-based calibration: after zero calibration, place the weight and enter the weight value to complete calibration.
3. After selecting weightless calibration, enter the sensor sensitivity. Then input the sensor range as the calibration value to complete the calibration.
