to return to the starting page
Note: from the first setting onwards, the time and date will flash.
These will also flash in the peak value pages.
• The voltage and current measurements are taken in TRMS (True RMS) by
means of sampling and analogue-digital conversion.
• The following formulas are used to calculate the system values:
System voltage
V
=
V1 + V2 + V3

Active system power
P
= P1+P2+P3
Reactive system power
