(5) Read the multimeter and change the middle current value on the display to match the
multimeter value. For example, if the multimeter value is 9.999 A, adjust the current
to 9.999 A using the control knob and arrow keys. Wait for the multimeter reading to
stabilize for accurate calibration.
(6) Press the Calibrate key to save the change and select the high current 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, a MIN VALUE or MAX VALUE message is
displayed for 1 second and the display shows the middle current calibration point
again. The display now shows the high current calibration point.
(7) Read the multimeter and change the high current value on the display to match the
multimeter value. For example, if the computed value is 19.499 A, adjust the current to
19.499 A using the control knob and arrow keys. Wait for the multimeter reading to
stabilize for accurate calibration.
(8) Press the Calibrate key to save the new calibration constants for the output current
and go to the OCP calibration mode.
(a) A CALIBRATING message is displayed for several seconds 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.
(b) If the calibration fails, a DAC CAL FAIL or ADC CAL FAIL message is displayed for
1 second and the display shows the CAL SETUP 3 for current calibration again.
(9) Press the Calibrate key to save the new OCP calibration constants and return to the
calibration mode.
(a) A CALIBRATING message is displayed for several seconds to indicate that the OCP
calibration is progressing and new OCP calibration constants of SETUP 4 are stored.
Then the display will return to the calibration mode.
(b) If the calibration fails, an OCP CAL FAIL message is displayed for 1 second and the
display shows the CAL SETUP 4 for OCP calibration again.
(10) Secure the power supply and turn off to exit the calibration mode.
