Following is the display of voltages when a 2Vpp+Vr connection mode is chosen
(two phase - phase plus earth voltage).
UAB
100.00 V
Displays the voltage value of phase A to phase B.
UBC
100.00 V
Displays the voltage value of phase B to phase C.
UN
3.15 V
Displays the earth voltage value.
Max UAB Rms
127.23 V
Displays the true RMS maximum voltage value for
phase A to phase B.
Max UBC Rms
127.28 V
Displays the true RMS maximum voltage value for
phase B to phase C.
Average UAB Rms
127.25 V
Displays the true RMS average voltage value for
phase A to phase B.
Average UBC Rms
97.88 V
Displays the true RMS average voltage value for
phase B to phase C.
P
0.00 kW
Displays the positive & negative active power; only
negative sign is shown.
The maximum measured value displayed is 9999MW.
If the measured value is above 9999MW this display
remains on the LCD.
Q
-0.10 kVAR
Displays the positive & negative reactive power; only
the negative sign is shown.
The maximum measured value displayed is 9999MVAr.
If the measured value is above 9999MVAr this display
remains on the LCD.
Cos (Phi)
1.00
Displays the three phases power factor.
