Power Measurement
�
Polarity configuration note:
when measuring load circuits with power absorptions, positive (‘+’ implied) w or kw (Real
Power) readings indicate correct measurement setups. negative readings (“-“ segment on)
indicate either the clamp-on jaws direction or the test leads polarity is reversed in such
cases. Correct the setups to get correct readings.
Power Measurement - Single Phase (Ø) (see figure 8)
Select the
Power
position.
Press
SELECt
button momentarily to select
W
(real power),
VAR
(reactive power) or
VA
(apparent power) measurement functions.
Connect CoM input to neutral or gRD.
Connect ‘ + ‘ input to the phase being tested.
Clamp jaws around the phase wire
The display will show reading,
W
(real power),
VAR
(reactive power) or
VA
(apparent
power) measurement and
Pf.
Power Measurement – 3 Phase (Ø) - 3 Wire (see figure 9)
Select the
Power
position.
Press
SELECt
button momentarily to select
W
(real power) or
VA
(apparent power)
measurement functions.
Connect CoM input to Ø 3 terminal .
Connect ‘ + ‘ input to Ø 1 terminal
Clamp jaws around to Ø 1 wire
The display will show reading,
W
(real power) or
VA
(apparent power) measurement
and
Pf.
write down the reading as kw1, kVA1
Connect CoM input to Ø 3 terminal .
Connect ‘ + ‘ input to Ø 2 terminal
Clamp jaws around to Ø 2 wire
The display will show reading,
W
(real power) or
VA
(apparent power) measurement
and
Pf.
write down the reading as kw2
