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
LCD
= W × VT,
VA
LCD
= VA × VT, VAR
LCD
= VAR × VT, WH
LCD
= WH × VT).
