(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 for the +6V supply.
The display shows the above message to indicate that the power supply is ready for the
voltage calibration of +6V supply.
(5) Select the first voltage calibration point for the +6V supply.
The display shows the first voltage calibration point for the +6V supply.
(6) Read the multimeter and change the first voltage value on the display to match the
measured voltage. For example, if the multimeter reading is 0.0860 V, adjust the
voltage to 0.0860 V using the control knob and resolution selection keys.
(7) Press the Calibrate key to save the change and select the second voltage calibration
point for the +6V supply.
(a) If the entered number is within an acceptable range, an ENTERED message is
displayed for 1 second. The display now shows the second voltage calibration point
for the +6V supply.
(b) If the entered number is not correct, an INVALID DATA message is displayed for 1
second and the display shows the first voltage calibration point again.
(8) Read the multimeter and change the second voltage value on the display to match the
measured voltage. For example, if the multimeter reads 5.9990 V, adjust the voltage to
5.9990 V using the control knob and arrow keys.
(9) Press the Calibrate key to save the new calibration constants for the +6V output voltage
and go to the current calibration mode for the +6V supply.
(a) If the entered number is within an acceptable range, a CALIBRATING message is
displayed for 1 second to indicate that the calibration is successful and that new
calibration constants of SETUP 1 are stored. Then, the display shows the above
message to indicate that the power supply is ready for the current calibration for
+6V supply.
(b) If the entered number is not correct, an INVALID DATA message is displayed for
1 second and the display shows the second voltage calibration point again. If the
calibration fails, a CAL FAIL message is displayed for 1 second and the display
shows the CAL SETUP 1 for the voltage calibration of the +6V supply again.
