Test Mode Button
The Test Mode button is located at the 3 o'clock position under the meter cover. Pressing the
button activates Test Mode. Test Mode is indicated by the “TEST” annunciator on the lower
left of the LCD. Pressing the button a second time activates Test Alternate Mode, enabling
the user to test a different energy quantity with the IR LED. Test Alternate Mode is
indicated by the “TEST” and “ALT” annunciators on the lower left of the LCD. Pressing the
button a third time will exit Test Mode and activate the Normal display.
If the TEST button is disabled through programming, the meter will not enter Test
Mode when the button is pressed.
