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)
1.
Select the Power position.
2.
Press SELECt button momentarily to select W (real power), VAR (reactive power) or VA
(apparent power) measurement functions.
3.
Connect CoM input to neutral or gRD.
4.
Connect ' + ' input to the phase being tested.
5.
Clamp jaws around the phase wire
6.
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)
1.
Select the Power position.
2.
Press SELECt button momentarily to select W (real power) or VA (apparent power)
measurement functions.
3.
Connect CoM input to Ø 3 terminal .
4.
Connect ' + ' input to Ø 1 terminal
5.
Clamp jaws around to Ø 1 wire
6.
The display will show reading, W (real power) or VA (apparent power) measurement
and Pf.
7.
write down the reading as kw1, kVA1
8.
Connect CoM input to Ø 3 terminal .
9.
Connect ' + ' input to Ø 2 terminal
10.
Clamp jaws around to Ø 2 wire
11.
The display will show reading, W (real power) or VA (apparent power) measurement
and Pf.
12.
write down the reading as kw2
