"POWER" FUNCTION

This function permits to display in real time the RMS value of AC/DC voltage, the peak and
ThdV value and the waveform of the voltage, the RMS value of AC/DC currents, the peak,
Thdl value and the waveform of the current. Furthermore, the instrument calculates and
displays the value of the active, reactive and apparent power and the value of the power
factors and cosϕ.

8.6.1. Symbols

The position POWER has two working modes:
METER
WAVE
For voltage and current harmonics see paragraphs 8.4.3 and 8.5.3 respectively.
These modes will be described in detail in the next paragraphs.
The symbols used are described below:
Symbol Description
V1 Voltage RMS value
freq Network frequency
I1 Current RMS value
P1 Active power
Q1 Reactive power
S1 Apparent power
pf1 Power factor
dpf1
cosϕ
The symbols "i" and "c" stand for reactive powers (Q), power factors (Pf) and cosϕ (dpf)
respectively inductive and capacitive.
