Functional Displays
Display transients that were captured –
each transient consisting of one pre-trig-
gered cycle, the triggered cycle and two
post-triggered cycles. All inputs are stored
when a transient is captured. Up to 50
transients can be stored, each consisting
of four cycles and up to six inputs for a
total of 1200 transient waveforms.
Voltage, current and power harmonics can be displayed in real time, in bargraph and text form, and stored in memory. Individual
harmonics can be analyzed by moving the horizontal cursor to that harmonic. Harmonic direction (source-to-load or load-to-source) can
be displayed for power harmonics. Harmonic sequencing (negative, zero and positive) can be displayed for volts or amps for all phases.

Information on screen (real-time or stored
data) can be sent to a printer using the
serial interface by simply pressing the print
button. You can store up to 12 screen snapshots

of the stored snapshots can be selected
and displayed by selecting it from the list.
Printing Snapshot Mode
Configuration is simple and straightforward. Simply press the setup button and select the
function you wish to configure. For example, to configure the input, select the desired

calculated in the 4-wire hookup.
Configuration
PowerPad’s direct access
system lets you see the
important information you
need at the press of a button.
Quickly review waveforms,
harmonics, transients, alarms
and recorded data on screen.
Setup is straightforward using
a combination of graphic and
