The third row displays real time TRMS voltage, frequency and %THD. The fourth
row displays the time and date. Press the down arrow to invert the display when the
unit needs to be plugged in upside down. Press the right arrow to brighten the dis-
play. The VPM display dims and enters a scrolling screen save mode when moni-
toring. Pressing any button exits the screen saver mode and temporarily brightens
the display.
Reviewing Events:
To review data, unplug the unit from the circuit being monitored. No data will be
lost if the unit is unplugged before powering down. Voltage, frequency and %THD
will flash intermittently indicating the loss of AC power. Press any key within 10
seconds to disregard the artificial loss event created by unplugging the unit. If no
key is pressed, a LOSS event will be logged at the time it was unplugged.
Unplugging the unit displays the review screen.

*(includes RUN events)
The keypad is operational in the review screen. Press the RIGHT ARROW to scroll
through event categories: SAG, SWL, IMP and THD. The count of individual voltage
events is displayed above each category. Press the DOWN ARROW to scroll
through menu options: Event Review, LOG Review and SETUP Review. LOG is a
chronological display of all logged events. SETUP provides access to nominal volt-
age selection, monitoring standards selection, date and time editing, and reset
options.
In the example above 5 sag events occurred in addition to 2 swell events, 4
impulse events and 12 THD events. 44 events are stored in the unit and 95%
battery life remains. Highlight an event category and press ENTER to display a
chronological log of those events. Highlight LOG and press ENTER to display a

Monitoring Voltage:
Press the power button to turn the unit on. Plug the unit into a live outlet. The
IDEAL logo will appear followed by a flashing lightning bolt for approximately 6
seconds. This delay allows the user to confirm the nominal voltage programmed as
well as prevent the unit from logging voltage events due to the initial connection to
the circuit. The nominal voltage selected is displayed above the lightning bolt. The
default nominal voltage is 120. The voltage displayed below the lightning bolt is
the actual live voltage and will flash intermittently with the lightning bolt icon. If the
unit is unplugged while lightning bolt is still on, no event will record.

Monitor Screen:
The monitor screen is displayed while the unit is plugged into AC power. This
screen displays real-time monitoring information and the count of voltage events
that have occurred. The unit is always actively recording while this screen is dis-
played. The top row displays the count of any events that have occurred since the
unit has been cleared. The second row displays the 4 voltage event categories
monitored:
SAG = Voltage Sag
SWL = Voltage Swell
IMP = Impulse
THD = Total Harmonic Distortion.
