PROVA 21 - Single-Phase AC Watt Measurement; Apparent and Reactive Power Measurement

17
III.3.1 Single Phase AC Watt
a. Connect the test leads to the voltage source in parallel with the load.
b. 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.
c. Select proper Watt range (W-mA or W-A).
d. Read the value shown on LCD in mW, W, or KW. The unit of watt is
automatically scaled.
III.3.2. Apparent Power (VA, KVA) and Reactive Power (VAR, KVAR)
a. Connect the test leads to the voltage source in parallel with the load.
b. 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.
c. Select proper Watt range (W-mA or W-A).
d. The value of mW, W, or KW will be displayed in LCD. The unit of watt is
automatically scaled.
e. Press the FUNC button once to display VA or KVA. The unit is automatically
scaled.
f. Press the FUNC button twice to display VAR or KVAR. The unit is
automatically scaled.
