“EPROM Change Procedure.” In Appendix D, “8500C/C+” refers to either 8500C or
8500C+, units.
This section contains instructions to test the 8500C/C+ system performance parameters. If a test step
fails. refer to the “Troubleshooting Guide” in Section 5.6 to locate the faulty component.
The functional tests ensure that the instrument is operating properly and within specifications.
The
functional test setups use, as much as possible. All the components (transducers, cables, etc.) that are
