5.1 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:
• Re-start the instrument. Each time the instrument is powered on, the selftest
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 IT7200 Programming Guide
for the list of error codes.
5.2 Cleaning and Maintenance
To ensure the safety function and performance of the instrument, please clean
and maintain the instrument properly.
• 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.
Clean the outside and the front panel screen of the instrument using a soft, lint
free, cloth slightly dampened with water. Use a brush to clean the dust on the
vent and cooling fans.
