Perform the Turn-On Checkout as directed in chapter 4.
NOTE:
The dc source must pass turn-on selftest before you can proceed with the verification
tests.

Voltage Programming and Measurement Accuracy

This test verifies the voltage programming, GPIB measurement, and front panel meter functions. Values
read back over the GPIB should be the same as those displayed on the front panel. Measure the dc output
voltage at the output terminals. Make sure the output mode switch is set to Normal and the sense
terminals are directly jumpered to the output terminals.
Action
1. Turn off the dc source and connect a DMM to the output
terminals.
2. Turn on the dc source with no load on the output. Set the output
voltage to 0 V and the output current to full scale (see table B-2).
Press Output On/Off to enable the output.
3. Record voltage readings at the DMM and on the front panel
display in the appropriate table.
4. Set the output voltage to the full scale rated voltage
(see Table B-2).
5. Record voltage readings at the DMM and on the front panel
display in the table.

Current Programming and Measurement Accuracy

This test verifies the current programming and measurement. Connect the appropriate current monitor
(see table B-1) as shown in figure B-1A.
Current Programming and Measurement (High Range)
Action
1. Turn off the dc source and connect the DMM and current monitor
as shown in figure B-1A.
2. Turn on the dc source, access the Input menu, and set the current
sense detector to DC.
3. Set the output voltage to 5 V and the current to 0 A. Press Output
On/Off to enable the output.
4. Divide the voltage drop across the current monitor by its resistance
to convert the value to amperes. Record the value.
5. Set the output current to its full scale value (see Table B-2).
