Power-up sequence
Self-test procedures are built into the Model 2110 for checking that the logic and measurement
hardware are functioning properly. Every time the instrument power is turned on, a set of test
procedures is performed to make sure the basic functions of the instrument work properly. If any error
occurs during self-test procedures, it indicates that parts of the instrument are not operating properly
and need to be serviced.
Refer to Error codes (on page 6-3
) for information about self-test error codes.
Erroneous self-test failures may occur if the power line voltage is set incorrectly. Errors may also
occur because of signals present on the input terminal during self-test procedures. Long test leads
can act as an antenna, causing pick-up of AC signals.
