1.
Apply power to the meter with the
jaw clear of any conductors.
2.
Set the rotary switch to the 3
φ
position.
3.
The LCD will show 3
φ
3W, 3
φ
4W,
and BAL symbols to indicate
balanced mode.
4.
If the watt reading is not zero, press
the DCA/DCW ZERO button once
to zero reading
5.
Insert the test leads into the input
terminals.
6.
Select one phase (R or L1) as COM and Connect the COM (black) terminal to the
same phase just selected (R or L1).
7.
Connect another test lead to the second phase (S or L2).
8.
Clamp on to the third phase (T or L3).
9.
The power clamp will automatically select proper range.
10. Read the Watt and PF values displayed on the LCD.
11. To view the KVA and KVAR data, press the NEXT button.
12. To view V and A, press the NEXT button again.
13. To return to the W and PF display, press the NEXT button again.
KVA/KVAR Dual Display
Follow steps 1 through 10. in the above section and press the NEXT button. Wait
approx. 2 seconds for the LCD to display the KVA and KVAR.
Voltage (V) and Current (A) Dual Display
Follow steps 1 through 10 in the above section and press the NEXT button twice. Wait
approx. 2 seconds for the LCD to display Voltage (V) and Current (A).
NOTE:
Specific selection of each phase is not required in 3
φ
balanced
power measurement mode. As long as each test lead and the jaws are
connected to different phases, the reading is always correct. The "+" sign
printed on jaw must face the power source for accurate measurement.
NOTE:
To find out if a load is capacitive or inductive, refer to the section
entitled "Phase Angle Measurements".
