Test descriptions
This section specifies what is actually checked by each test in the instrument
self-test. Some of the tests may only be applicable to one method of invocation
(for example, from the front panel). If this is the case, it is specified in the test
description. Most of the tests have an associated error message which is added to
the error queue if the test fails. The exception to this is the bitmap display test. For
more information on the error messages, refer to the N432A Thermistor Power
Meter User's Guide.
