Setup options:
Setup Screen
The SETUP menu accesses the nominal voltage, monitoring standard, time, date
and reset options. Press ENTER while SETUP is highlighted to display the Set
Nominal/Set Standard screen.
Setting Nominal Voltage and Standard
There are 8 nominal voltage selections available to cover a broad range of coun-
tries and applications. The default voltage is 120V. Highlight Set Nominal and
press ENTER to highlight the current voltage setting.
Press Up/Down arrow to scroll through nominal voltages available. Nominal set-
tings are 100, 110, 120, 200, 208, 220, 230 and 240V. Press ENTER to change the
nominal voltage setting or for capturing only the voltage events. Press LEFT
ARROW to escape out of the selection menu without changing the setting.
Setting the Monitoring Standard
Refer to the standards table to view available standards and their corresponding
event triggers. The default standard is the ITIC. This standard is suitable for detect-
ing events that will affect most equipment on branch circuits. To select another
standard, highlight Set Standard and press ENTER.
Press UP or DOWN ARROW to scroll through the other monitoring standards.
Press ENTER to change the monitoring standard. Press the LEFT ARROW to escape

THD Detail:
In the Review screen, press ENTER when THD is highlighted to display the THD
Log screen. RIGHT ARROW to display THD Detail.
Live monitoring displays real-time %THD. A THD event is logged only if the %THD
surpasses 3.0% during a monitoring period. The unit logs the maximum % THD
for the monitoring period. The THD measurement is a 128 point FFT every 4th
cycle and calculates the THD to the 51st harmonic. Press the Left Arrow to return to
the Review Screen
Log and Set Up screens:
Log Screen
Press the DOWN ARROW in the Review Screen to highlight Log. Press ENTER to
display the chronological event log. The Log Screen displays a cumulative record
of all events, starting with the most recent event recorded.
In addition to voltage events, the unit logs RUN and LOSS events. RUN events are
markers for when the unit senses AC power. Either when starting a monitoring
cycle or when power returns after a loss. A LOSS is the when power is lost*. To
determine the duration of a power loss, subtract the Run event from the prior Loss
event. Press RIGHT ARROW to display the event detail.
*Event outside of the operating range of the unit (15V) may also record as a loss. Losses are
also logged in the SAG event log.
