Indicated values
Voltage/current/electric power (effective/reactive/apparent)/
power factor
Voltage
Each interphase voltage and average interphase voltage of electric wires are displayed.
RMS (true root mean square value) and MEAN (RMS value calibrated by average rectification) can
be selected.
Status
1: UV interphase voltage 2: VW interphase voltage 3: WU interphase voltage
∑
: average interphase voltage (in 3P3), UV interphase voltage (in 1P2)
Displayed unit
V
* Treated as 0.0V when voltage is 0.2V or below and current is 0.02A or below.
Current
Each phase current and average phase current of electric wires are displayed.
Current is limited to the true root mean square value.
Status
1: U phase current 2: V phase current 3: W phase current
∑
: average interphase current (in 3P3), UV phase current (in 1P2)
Display unit
A
* Treated as 0.00A when voltage is 0.2V or below and current is 0.02A or below.
Electric power (effective/reactive/apparent)
As for electric power, effective power, reactive power and apparent power are displayed
respectively.
Status
∑
Effective power:
The actual electric power used for load. The average cycle of the product of
instantaneous voltage and instantaneous current.
Display unit
W
Reactive power:
Electric power that goes back and forth between the load and power supply
without being consumed. Square root (square of apparent power - square of
effective power)
Display unit
var
Apparent power:
The product of effective voltage (average interphase voltage) and effective
current (average phase current).
Display unit
VA
