4.4.12 Self-Test
Self-test procedures are built in M3500A for checking that the logic and
measurement hardware are functioning properly. Every time when the
multimeter is powered on, a set of test procedures is performed to make
sure the basic function of the multimeter works properly. If any error
occurs during self-test procedures, it indicates that parts of the
multimeter are not operating properly and need to be serviced.
Warning! Erroneous self-test failures may occur if the setting of
power line voltage is incorrect. Errors may also occur because of signals
present on the input terminal (front and rear) during self-test procedure.
Long test leads can act as an antenna causing pick-up of ac signals.
How to execute Self-test
You may execute a complete self-test by front panel operation. This test
procedure provides more tests for the hardware of M3500A than the
power-on tests. Please follow the Figure 4-38 direction and procedure
below to perform the complete self-test.
