and the GPIB connector.
Step 3. Crimp the appropriate ring terminal (2) onto the end of the ground
wire.
Step 4. Place the ring terminal onto the threaded end of the binding post. Re-
install the binding post on the chassis with the washer and nut (3).

Troubleshooting
Before performing the Overall Troubleshooting procedures, perform
the Operating Checkout procedure in the beginning of this chapter.
If the power system passes selftest and there are no obvious faults,
perform the verification procedures in Appendix B to determine if
any power modules are not calibrated, or are not operating properly.
This will help isolate a problem to a specific power module.
