Chapter 3 Calibration Procedures

General Calibration/Adjustment Procedure

7Pressing the "Calibrate" key saves the change and selects the second

voltage calibration point for the +6V supply.

If the entered number is within an acceptable range, an "ENTERED" message

appears for one second. The display now shows the second voltage calibration

point for the +6V supply. If the entered number is not correct, an "INVALID

DATA" message appears for one second and the display shows the first voltage

calibration point again.

8Read the DVM and change the second voltage value on the display to

match the measured voltage.

For example, if the DVM reads 5.9990 V, adjust the voltage to 5.9990 V using

the knob and arrow keys.

9Pressing the "Calibrate" key saves the new calibration constants for

the +6V output voltage and goes to the current calibration mode for

the +6V supply.

If the entered number is within an acceptable range, a "CALIBRATING"

message appears for one 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.

If the entered number is not correct, an "INVALID DATA" message appears for

one second and the display shows the second voltage calibration point again.

If the calibration fails, a "CAL FAIL" message appears for one second and the

display shows the "CAL SETUP 1" for the voltage calibration of the +6V supply

again.
