Select Power with the rotary switch.
In this measuring mode you can get the following values for each phase (A, B,
C):
•
Power (P) in W (for each phase and its sum P
tot
).
•
Reactive power (Q) in var (for each phase and its sum Q
tot
).
•
Apparent power (S) in VA (for each phase and its sum S
tot
).
•
Distortion power (D) in VA (for each phase and its sum D
tot
).
•
Power factor (PF) and the average PF for the three phases.
•
Cos
ϕ
and the average cos
ϕ
for each of the three phases.
•
Active energy (EP) in kWh.
•
Reactive energy (EQ) in kVAR.
Measurement
You can determine the instantaneous values and store them. You can also
record the values with the recorder function.
If you select this measurement mode you will get the following display:
