- Environmental Check: Ensure the operating environment remains within specified temperature and humidity ranges.
No user-serviceable parts are inside. Refer all internal servicing to qualified technicians.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display/Power off | No power supply or incorrect wiring. | Check power supply connections (85~300VAC). Verify wiring according to the diagram. |
| Incorrect readings | Incorrect CT connection, wrong CT ratio setting, or wiring error. | Ensure CTs are connected correctly (polarity). Verify CT ratio settings in the meter configuration. Recheck all wiring. |
| Communication issues (TCP) | Incorrect network settings, cable fault, or network configuration problem. | Verify IP address, subnet mask, and gateway settings. Check Ethernet cable connection. Consult network administrator. |
