7. Řešení problémů
This section addresses common issues you might encounter with your ADL400 meter.
7.1. Inaccurate Power or Energy Count
Problém: After the meter is powered on, the power or energy count is inaccurate.
Řešení:
- Switch the meter display to show power (active power P, power factor λ).
- Check whether the power display is negative or not.
- Verify if the power factor is between 0.9-0.95.
- Check whether the incoming and outgoing wires of the current signal wire are connected reversely. The incoming wire must be the same as the incoming wire end of the instrument and consistent with the wiring diagram on the instrument.
