(10) Read the multimeter and change the high voltage value on the display to match the
measured voltage. For example, if the multimeter reads 19.495 V, adjust the voltage to
19.495 V using the control knob and arrow keys.
(Calibrate) key to save the new voltage calibration constants and go to
(11) Press the
the OVP calibration mode.
(a) A CALIBRATING message is displayed for 1 second to indicate that the voltage
calibration is progressing and new voltage calibration constants for SETUP 1 are
stored. Then, the display shows above message to indicate that the power supply is
ready for the OVP 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 1 for voltage calibration again.
(Calibrate) key to save the new calibration constants for OVP circuit
(12) Press the
and go to the current calibration mode.
(a) A CALIBRATING message is displayed for 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.
(b) If the calibration fails, an OVP CAL FAIL message is displayed for 1 second and the
display shows the CAL SETUP 2 for OVP calibration again.
c. Front Panel Current and OCP Calibration
(1) Connect equipment as shown in figure 7.
(2) Select the low current calibration point. The display shows the low current calibration
point
(3) Read the multimeter and change the low current value on the display to match the
multimeter. For example, multimeter reading is 0.499 A, adjust the current to 0.499
A using the control knob and arrow keys. Wait for the multimeter reading to stabilize
for accurate calibration.
(4) Press the Calibrate key to save the change and select the middle 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 low current calibration point again.
The display now shows the middle current calibration point.
