- After power-on, check whether the display is normal and confirm there are no error codes.
Overview of Key Parameter Settings
| Parameter | Description | Typical Setting |
|---|---|---|
| Measurement unit | Display unit selection | m / % / bar |
| Lower range limit | Measured value corresponding to 4 mA | 0 m |
| Upper range limit | Measured value corresponding to 20 mA | 10 m |
| Relay mode | Limit or pump control | Limit alarm |
Common Issues and Maintenance Recommendations
Abnormal Display
If the displayed value fluctuates, first check the sensor wiring and shield grounding. Re-calibrate the range if necessary.
Relay Not Operating
Confirm whether the relay mode and setpoint are correct, and check whether the load exceeds the contact capacity. Regularly clean the instrument surface to prevent dust from affecting heat dissipation.
