Remote Testing

To invoke the remote self test, the IEEE 488.1 compliant standard command,
*TST? is used. This command runs a full self test and returns one of the
following codes:
• 0 - no tests failed
• 1 - one or more tests failed
The remote self test consists of the following tests:
• ROM checksum
• RAM
• RAM Battery
• Display Assembly
• Calibrator
• Measurement Assemblies
• Communications Assembly (Implicit)
The communications assembly is tested implicitly, in that the command will
not be accepted or return a result unless the GPIB interface is functioning
correctly.
Refer to
individual test.
When the *TST? command is executed, the screen is cleared. As each test
takes place, the name of the test is listed on the screen. While a test is running,
the message "Testing..." appears next to the name of the test. As each
stage of the test is completed, the message "Testing..." is replaced by
either the message "Passed" or "Failed".
