Turn on the calibration mode by holding down the "Calibrate" key as you
turn on the power supply until you hear a long beep.
2 Unsecure the power supply if secured. (See page 67)
3 Press "Calibrate" key to move down menu to voltage calibration menu.
A "
VOLT1 CAL " is displayed. Press "Calibrate" key to select the low
voltage calibration point.
