The RESET pushbutton is used to set the time interval
for 15 minute averages, the elapsed time indicator,
and the imported, exported, and accumulated kWh,
kVARh and kVAh. The reset function has a prompt to
avoid accidental operation.
The EDIT pushbutton is used to set the unit in set up
mode. In set up mode the protocol, the delta or wye
configuration, the port baud rate, the address, and call
home phone number are selected. If password protec

LCD DISPLAY USAGE
The LCD display is a 16 character by two-line display.
When the unit is first powered up, the LCD displays
"Executing Application", then switches to the "top
level" display, which shows the Model Number and
software version.
If no keys are pressed, the LCD switches to metering
mode and alternately displays the various parameters
measured. This is called scrolling. When the down
arrow key is pressed, "Freeze Display" LED lights up
and the display locks on the last screen. Press
again and the display resumes scrolling, or it will
automatically resume scrolling after five minutes.
The Metering screens include:
