PF (Power factor):
(apparent power). It is important to note that the closer the power factor is to "1" the more resistive the
DUT is. The closer the power factor is to 0 the more reactive (inductive or capacitive) the DUT is.
Reactive Current:
The current component due to the reactive impedance of a load. Also called
imaginary current.
Real Current:
The current component due to the resistance of a load.
Resistance:
The property of a substance that impedes current and results in the dissipation of
power in the form of heat. The practical unit of resistance is the ohm (Ω). Symbol = R
Return:
The path by which current returns to a source.
RMS:
The Root Mean Squared value of a voltage or current waveform. An RMS waveform delivers
the same amount of energy to a load as a DC waveform of the same value. For a sinusoid, the RMS
value is .707 x the peak value.
Total Current
: The vector sum of the real current component and the reactive current component
produced by an applied voltage.
A rating of instantaneous power found by multiplying an instrument's maximum output current by
VA:
its maximum output voltage.
Voltage:
The force which causes current through an electrical conductor, given in volts (V).
Symbol = V

1.4. Safety

This product and its related documentation
must be reviewed for familiarization with
safety markings and instructions before
operation.
This product is a Safety Class I instrument
(provided with a protective earth terminal).
Before applying power verify that the
instrument is set to the correct line voltage
(115 or 230) and the correct fuse is
installed.
This product carries an NRTL (Nationally
Recognized Testing Laboratory) and
comes equipped with an audible and visual failure indicator.

Power Factor = W/VA where W =Watts (Real Power) and VA =Volts x Amps
The HYAMP III produces
voltages and currents that
can cause harmful or fatal
electric shock. To prevent
accidental injury or death,
these safety procedures
must be strictly observed
when handling and using the
test instrument.
SAFETY
