Chapter 5: Troubleshooting

To troubleshoot the instrument
The troubleshooting procedure is used to isolate problems to a faulty assembly. When you find
the faulty assembly, use the disassembly and assembly procedures in chapter 6 to replace the
assembly.
The primary procedural tool in this section is the flowchart. The flowchart contains the entire
troubleshooting path from a failed instrument to a working one, and will direct you in an orderly
manner through the possible failure symptoms. Reference letters on the flowcharts point to
procedural steps that explain the brief instructions in the chart. Do not try to troubleshoot by
following only the reference text because the text is not in the correct order for troubleshooting.
Instead, simply follow the flowchart.
If you are unfamiliar with this instrument, start with the Primary Trouble Isolation Flowchart on
