General Calibration/Adjustment Procedure

10Read the DVM and change the high voltage value on the display to match the measured voltage.

For example, if the DVM reads 19.495 V, adjust the voltage to 19.495 V using the knob and arrow keys.

V HI 19.495 V

11Pressing CalibrateError (Calibrate) key saves the new voltage calibration constants, and goes to the OVP calibration mode.

CAL SETUP 2

A ‘‘CALIBRATING’’ message appears for one second to indicate that the voltage calibration is progressing and new voltage calibration constants of ‘‘SETUP 1’’ are stored. Then, the display shows above message to indicate that the power supply is ready for the OVP calibration.

If the calibration fails, a ‘‘DAC CAL FAIL’’ or ‘‘ADC CAL FAIL’’ message appears for one second and the display shows the ‘‘CAL SETUP 1’’ for voltage calibration again.

12Pressing Calibrate (Calibrate) key saves the new calibration constants for OVP circuit and goes to the current calibration mode.

CAL SETUP 3

A ‘‘CALIBRATING’’ message appears for about several seconds to indicate that the OVP calibration is progressing and new calibration constants of ‘‘SETUP 2’’ are stored. Then, the display shows the above message to indicate that the power supply is ready for the current calibration.

Connect an appropriate shunt 0.01 9 across the output terminals, and connect a digital voltmeter across the shunt resistor for the current calibration.
