1Turn 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 62)
3 Press "Calibrate" key to move down menu to voltage calibration menu.
A "VOLTAGE CAL" is displayed. Press "Calibrate" key to select the
low voltage calibration point.
