If You Have Problems; If The Mainframe Does Not Operate - HP 54753A User Manual

If You Have Problems

Review the procedure being performed when the problem occurred. Before
calling Hewlett-Packard or returning the unit for service, a few minutes spent
performing some simple checks may save waiting for your instrument to be
repaired.

If the Mainframe Does Not Operate

Please make the following checks:
1 Is the line fuse good?
2 Does the line socket have power?
3 Is the unit plugged in to the proper ac power source?
4 Is the mainframe turned on?
5 Is the rear-panel line switch set to on?
6 Will the mainframe power up without the plug-in module installed?
If the mainframe still does not power up, refer to the optional HP 83480A,
54750A Service Guide or return the mainframe to a qualified service
department.
