5-26. Troubleshooting Guide
A troubleshooting guide is presented in Table 5-7. The guide is structured
around the performance tests presented earlier in this chapter. To use this
guide, complete the performance tests and note any discrepancies in
performance. Then locate the test, symptom, and possible cause of
malfunction in Table 5-7. When several possible causes of malfunction are
listed, they are listed in order beginning with the most probable to the least
probable. A section about troubleshooting the power supply is also included.
The following troubleshooting techniques can be helpful:
• When troubleshooting, remember to use the switch decoding self-test to
determine whether the microcomputer properly interprets the function
and range selection.
