8. Verify the bias voltage output is within the limits for the 10 V range shown in Table 17-3.
9. Repeat steps 6 and 8 for an output voltage of -10.000 V.
10. Press the OUTPUT key to turn off the output.
11. Repeat steps 5 through 10 for the 30 V bias voltage range with both +30.00 V and -30.00 V
output voltages.
12. After verifying both ranges on channel 1:
a. With the power off, make connections to the channel 2 INPUT and OUTPUT connectors
(see Figure 17-4 for connections)
b. Repeat steps 5 through 11 verifying the acurracy of channel 2 (press the SRC2 key to
select channel 2).
