Output Check
Voltage and Frequency Check
Follow the steps below to check basic voltage output with no load connected.
1.
Turn on the AC power source. The display will show the OFF annunciator above the
voltage display.
2.
Using the numeric keypad or the rotary knob, enter a voltage value. The voltage display
will show the value you entered. If entering with the numeric keypad, press
