General Calibration/Adjustment Procedure

17Pressing the ‘‘Calibrate’’ key saves the change and selects the high current calibration point. (‘‘I HI 6.900 A’’ - E3634A model)

I HI 19.500 A (E3633A)

If the entered number is within an acceptable range, an ‘‘ENTERED’’ message appears for one second. If the entered number is not correct, an ‘‘MIN VALUE’’ or ‘‘MAX VALUE’’ message appears for one second and the display shows the middle current calibration point again. The display now shows the high current calibration point

18Read the DVM and change the high current value on the display to match the computed current (DVM reading ¸ by shunt resistance).

For example, if the computed value is 19.499 A, adjust the current to 19.499 A using the knob and arrow keys.

Notice that you should wait for the DVM reading to stabilize for accurate calibration.

19Pressing the ‘‘Calibrate’’ key saves the new calibration constants for the output current and goes to the OCP calibration mode.

CAL SETUP 4

A ‘‘CALIBRATING’’ message appears for one second to indicate that the current calibration is progressing and new calibration constants of ‘‘SETUP 3’’ are stored. Then, the display shows the above message to indicate that the power supply is ready for the OCP calibration.

If the calibration fails, an ‘‘DAC CAL FAIL’’ or ‘‘ADC CAL FAIL’’ message appears for one second and the display shows the ‘‘CAL SETUP 3’’ for current calibration again.
