4.2.6 MEASUREMENTS Screens

The i/iX Series uses a DSP based data acquisition system to provide extensive information regarding
the output of the Source. This data acquisition system digitizes the voltage and current waveforms and
calculates several parameters from this digitized data. The results of these calculations are displayed
in a series of measurement data screens. A total of three measurement screens are used to display all
this information.

Figure 4-7: MEASUREMENT Screen

The Measurement screens available on the iX Series are not menus in that no changes can be made
anywhere. Instead, these screens provide load parameter readouts. The measurement screens can
be reached by successively pressing the MEAS key, which will toggle to all available screens. Note
that for i Series models, only the first two screens are available. For the iX series, all three
measurement screens are available.

The PHASE key may be used to toggle through each output phase’s measurement screens. The
selected phase will be indicated by the phase LED’s to the left of the LCD display. If all three phases
are selected, data is only shown for phase A.

The following parameters are available in the measurement screens:

ENTRY

DESCRIPTION

MEASUREMENTS

1

VOLTAGE

This value is the true rms output voltage measured at the voltage
sense lines.

CURRENT

This value is the true rms output current drawn by the load.

FREQ

The output frequency is measured at the sense lines.

TRUE POWER

This value is the real power.

MEASUREMENTS

2

VA POWER

This value is the apparent power.

POWER FACTOR

This readout shows the power factor of the load.

PEAK CURR

This readout reflects the highest peak current value detected at the
output. This is a track and hold peak current measurement. To
measure inrush current for a unit under test, open the output relay
and reset the peak current value using the BACK key. Then program
the output voltage and frequency and turn on the output relay. The
peak current measurement will continuously track the maximum
current value detected until reset. See also PEAK CURRENT in
MEASUREMENTS 3 screen.
