5.4 Troubleshooting checks
Check operational requirements. If your instrument is
not operating as expected, review the operational
requirements listed in the product specifications and
recommended setup and operating procedures.
Check fuses. The power switch and fuse holder are
beside the power cord connector on the left side of the
instrument. Turn the power switch o and disconnect
the power cord. Use a small flat-bladed screwdriver to
pry open the fuse compartment door. Slide out each fuse
holder. Check for a blown fuse. Test the fuses with a
continuity checker or ohmmeter or replace with new
fuses.
Check error messages. The software of your instrument
is designed to display specific error messages that help
you discover the source of your problem.
