(1) Unsecure the power supply according to step a (4) above.
(2) Disconnect all loads from the power supply and connect a multimeter across output
terminals.
(3) Turn on the calibration mode.
(a) Turn on the calibration mode by pressing the Calibrate key while simultaneously
turning on the power supply, then continue to hold the Calibrate key for about
5 seconds until a beep is heard.
(b) Make certain that the power supply is in CV mode. If the power supply is not in CV
mode, an error occurs.
(4) Move down a level to the voltage calibration mode.
(5) Select the low- end voltage calibration point.
(6) Read the multimeter and change the low voltage value on the display to match the
measured voltage using the control knob and resolution selection keys.
(7) Save the changes and select the middle voltage calibration point.
(a) If the entered number is within an acceptable range, an `ENTERED message is
displayed for 1 second.
(b) If the entered number is not correct, an error message will be displayed for 1 second
and a beep is emitted. Go back to the low, middle, or high voltage calibration point
and repeat the adjustment.
(8) Read the multimeter and change the middle voltage value on the display to match the
measured voltage using the control knob and resolution selection keys.
(9) Save the changes and select the high voltage calibration point.
(10) Read the multimeter and change the high voltage value on the display to match the
measured voltage using the control knob and resolution selection keys.
(11) Save the changes and go to the OVP calibration mode.
(a) If the calibration fails, an error message will be displayed for 1 second. Go back to
the voltage calibration mode again. A VOLTAGE CAL message is displayed.
(b) The above message is displayed to indicate that the power supply is ready for the
OVP calibration.
