Unit Care and Maintenance
Check Unit Internal Resistance (Test for Shorts)
This section deals with “normal function” test proce dures, and
includes all steps necessary to ensure that the transformer is
operating within specified para meters prior to use. A digital
multimeter (an example is shown in Figure 8.2.1) capable of
measuring DC and AC voltage and resistance will be required
to perform some of the tests. These functional test procedures
should become routine.
