User manual
Fundamental Apparent Power: S1 — The fundamental apparent power S1 in
Volt-Ampere (VA) is measured according to:
Fundamental Power Factor: PF1 — The dimensionless parameter fundamental power
factor PF1 is measured as the ratio between fundamental active power P1 and
fundamental apparent power S1:
Nonfundamental Apparent Power: SN — The nonfundamental apparent power SN in
Volt-Ampere (VA) is measured according to:
Current Total Harmonic Distortion: THDI — This dimensionless parameter is measured
using the approximation formula below, which is accurate within 1% for voltages with
THDV < 0.05 and for currents with THDI > 0.4. For values outside this range it's an
indicative approximation.
