Chapter 3 Calibration Procedures
General Calibration/Adjustment Procedure

To calibrate the output voltages and currents of the power supply from the front panel,
proceed as follows:
1 Unsecure the power supply.
To calibrate the output voltage and current, you must unsecure the power supply
according to the procedure given on page 66.
2 Disconnect all loads from the power supply and connect a DVM across output
terminals of the +6V output.
3 Turn on the calibration mode.
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.
Make sure 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 DVM and change the first voltage value on the display to match the
measured voltage.
For example, if the DVM reading is 0.0860 V, adjust the voltage to 0.0860 V using
the knob and resolution selection keys.
