10.1 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:
•
•
10.2 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:
ERRor? to view the self-test error. Please refer to IT-M3400 Programming
Guide for the list of error codes.
Ensure that all test cables connections are removed when self-test is
performed. During self-test, errors may be induced by signals present on
external wiring, such as long test leads that can act as antennae.
To prevent electrical shock, disconnect the instrument from AC mains
power and disconnect all test leads before cleaning.
Do not use detergent or solvents.
Do not disassemble the instrument and attempt to clean internally.
