Installation and Wiring Steps
Correct installation and wiring are the foundation for ensuring the stable operation of the RIA15. Please follow the steps below:
- Confirm that the power supply is within the 12~35 V DC range, and turn off the power.
- Fix the RIA15 on the instrument panel and ensure that the front panel sealing ring is pressed tightly.
- Connect the 4~20 mA signal line according to the terminal markings, paying attention to polarity.
- After checking that the wiring is correct, turn on the power and observe whether the display is normal.
- If you need to adjust the display range or decimal point, enter the parameter setting menu to modify it.
For detailed wiring diagrams, please refer to the electrical connection chapter in the RIA15 Chinese Manual.pdf.
Operation and Parameter Settings
Display Mode Switching
The RIA15 supports multiple display modes, including real-time measured value, peak hold, and alarm status. It can be switched quickly via the front panel buttons to meet the needs of different working conditions.
Range and Decimal Point Settings
Users can customize the display range and decimal point position in the settings menu. Specific operations:
- Long press the "SET" key to enter the parameter menu.
- Use the "▲" and "▼" keys to select parameter items.
- Press the "SET" key to confirm and save the settings.
After the settings are completed, the instrument automatically returns to measurement mode without restarting.
Common Problems and Maintenance
To extend the service life of the RIA15, it is recommended to regularly check the wiring terminals and sealing status. Common problems and solutions are as follows:
- No display reading: Check whether the power and signal lines are reversed or broken.
- Large reading fluctuation: Confirm that the signal source is stable, and increase filtering if necessary.
- No response from buttons: Try powering off and restarting. If it still does not work, contact after-sales service.
