III.5 Measurement of Single Phase AC Power Quality
NOTE: If the peak value of the input AC current or AC voltage is greater than the
maximum value of the range, then symbol of OL will be displayed.
NOTE: If the VT ratio is not 1, the readings of shown in LCD is equal to the W, VA,
and VAR values measured by the tester multiplied by VT ratio (W

= VA × VT, VAR

a. Set the rotary switch at the 1 Phase position
b. Connect the test leads to the voltage source in parallel with the load.
c. Clamp on one of the wire to the load. The current should flow from the front of
the tester to the side of the battery cover
