Power calculation mode ( P.cAL ):
Mode 1: Reactive power calculation (rEAc)
Active power P and reactive power Q are measured directly and apparent power
S =
√
P
2
+ Q
2
Mode 2: Non-active power calculation (nAct)
Active power is measured directly, apparent power S = V
×
I (where V, I - rms
voltage and currents) and non-active power N =
√
S
2
- P

Mode 1 is recommended for electrical networks with low harmonic distortion (voltage
THD
<
5%, current THD
<
10%); Mode 2 is recommended for all other cases.
