- Device trips frequently:
- Check the current load on the circuit. It might be exceeding the set over-current protection value. Review and adjust over-voltage, under-voltage, or leakage protection settings if they are too sensitive for your application. Check for actual electrical faults.
- Incorrect readings (voltage, current, kWh):
- Use the calibration function in the manual settings or app to adjust voltage, current, or kW readings if you have a reference meter.
- Cannot reset to factory settings:
- The provided information does not detail a specific factory reset procedure. If encountering persistent issues, try re-pairing the device with the app, which often resets some settings. For advanced resets, consult TOMZN support.
