column are for a post-adjustment verification only.
8. Call
PS Read Output with the following parameter:
• Channel =
ps/+6V
9. Subtract the DMM reading from step 7 from the DC power supply Actual Voltage Level
reading in step 8. Verify that calculation falls between the limits in Table 20 or 21.
10. Repeat steps 5 through 9 for each verification point on this channel.
11. Call
