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.
