Installation Guide
Selection of Installation Location
The correct installation location is crucial to measurement accuracy. Avoid installation in areas with large vibration, severe temperature changes or strong electromagnetic interference. At the same time, ensure that the sensor probe can fully contact the material flow.
Installation Steps
- Turn off the equipment power and confirm that the installation environment is safe.
- According to the site conditions, fix the instrument on the bracket or flange.
- Adjust the probe angle so that its insertion depth into the material meets the requirements.
- Connect the power cable and signal cable, paying attention to correct polarity.
- Check whether all connections are firm, then power on for testing.
Operating Instructions
Power-on and Calibration
After power-on, the instrument enters the self-test state. When using for the first time or changing materials, it is recommended to perform zero calibration and span calibration. For specific operations, please refer to the calibration chapter in the manual.
Daily Operation
- View the real-time moisture value through the display.
- Use buttons or remote communication to set parameters.
- Record data regularly to facilitate trend analysis.
Maintenance and Troubleshooting
Daily Maintenance
- Clean the probe regularly to prevent material adhesion from affecting measurement.
- Check whether cables and connectors are damaged.
- Avoid mechanical impact on the probe.
Common Faults and Handling
| Fault phenomenon | Possible cause | Handling method |
|---|---|---|
| No display | Power not connected | Check the power supply line |
| Abnormal measurement value | Probe contamination or calibration failure | Clean the probe and recalibrate |
| Unstable signal output | Loose wiring or interference | Tighten wiring and stay away from interference sources |
Precautions
- Do not use non-explosion-proof instruments in flammable and explosive environments.
- Be sure to cut off the power before installation and maintenance.
- Non-professionals should not disassemble the internal parts of the instrument.
