NOTE A majority of test set problems involve only the test leads, i.e. the High
Voltage Test Cable and the Low Voltage Test Leads. Be especially alert to
the condition of these items. They can be readily tested by following the
procedures in ”Running Other Tests” on page 4-42.
Troubleshooting Resources
The operator should consult this chapter first when a problem appears. It will
help isolate the problem to the M4200c or the M4100 and will point to the
most appropriate resources available to resolve the problem as quickly as
possible. There are four categories of resources available, and these are
summarized in Table 4.2.
Table 4.1 Quick Checks: Can You Answer Yes To These Items:
