Power (Watts, VAr, VA, WDC, PF)
Help determine system efficiency by measuring the power exerted
by the system. The actual power consumed by the system is called Active
Power and is measured in watts (W or kW). Reactive loads, inductors
and capacitors, dissipate zero power, but they drop voltage and draw
current giving the deceptive impression they do dissipate power. This is
called Reactive Power and is measured in Volt-Amps-Reactive (VAr). The
combination of reactive and real power is called Apparent Power and
is the product of a systems voltage and current, without phase angle
consideration. Apparent Power is measured in Volt-Amps (VA).
Power Factor (PF) is the ratio of the power the system draws from
the main power supply and the power the system actually consumes. An
ideal PF is 1, meaning the system consumes all the power it draws. Due to
inductive and capacitive loads of the system however, this is not possible.
To take the power reading you need to measure both voltage and
amperage simultaneously. Connect test leads to main power supply
terminals and secure amp clamp around the same line that the positive
(red) test lead is connected to.
See Power Factor in top display and Power in bottom display. Press
SELECT to toggle Active Power (W), Reactive Power (VAr), Apparent Power
(VA) and DC Power (W).

CAUTION! DO NOT MEASURE VOLTAGE LINES OR EXPOSE THE METER TO
LIVE POWER LINES EXCEEDING 750VAC/1000VDC NOMINAL VOLTAGE.
