6.1 Instrument Self-Test
Self-test checks that the minimum set of logic and power mesh systems are
functioning properly. Self-test does not enable the output or place any voltages
on the output. Self-test can be achieved in two ways:

6.2 Cleaning and Maintenance
To ensure the safety function and performance of the instrument, please clean
and maintain the instrument properly.
Re-start the instrument. Each time the instrument is powered on, the self-
test is performed. This test assumes that the instrument is running.
SCPI command: *TST?. If the return value is 0, the self-test passes; if it is 1,
the self-test fails. If the self-test fails, please send command SYSTem:ER-
Ror? to view the self-test error. Please refer to IT-M3100 Programming
Guide for the list of error codes.
Ensure that all test cables connections are removed when self-test is per-
formed. During self-test, errors may be induced by signals present on ex-
ternal wiring, such as long test leads that can act as antennae.
