4.1.14 Maximum current
The RMS current is averaged for 10 line periods (200 ms in the 50 Hz system). The
maximum current average of the recording interval is stored in this register.
4.1.15 Minimum voltage
The RMS voltage is averaged for 10 line periods (200 ms in the 50 Hz system). The
minimum voltage value of the recording interval is stored in this register.
