Test procedures
Before each test procedure, set the UUT to its power-up conditions. To avoid switching the
instrument off and back on, reset the UUT by selecting:
[MEM] [Factory Recall]
At the end of this chapter are a set of results tables which give all the test points for each of the
tests. These tables should be photocopied and used to record the results of all the measurements
taken.
Tests for the options, where necessary, are included with the tests for the standard instrument.
