Single-Phase Power & 3-Phase Balanced-Load Power Functions
Set the slide-switch function-selector to the “3~Bal • 1~” Power position.
• Default at last selected function.
• Press “3~Bal • 1~” button momentarily to toggle between “Single-
Phase” and “3-Phase Balanced Load” Power functions. Annunciators “
” and “3~” turn on respectively.
• Press SELECT button momentarily selects between W (real power), VAR
(reactive power), VA (apparent power) & kWHr (real-time readings or
stored result) functions. In W (real power), VAR (reactive power), or VA
(apparent power) function:
1. PF (Total Power Factor) is displayed automatically in the secondary mini
display.
2. Annunciator “A-lags-V” turns on to indicate an inductive circuit is
being measured. That is, the Current waveform is lagging the Voltage
waveform, and the phase-shift angle θ is “+”.
3. On the contrary, together with significant PF values, WITHOUT
“A-lags-V” being turned on indicates that a capacitive circuit is being
measured. That is, the Current waveform is leading the Voltage
waveform, and the phase-shift angle θ is “-”.
