Functional Test
The procedure in this section is used to quickly verify that the multimeter is
functioning. This test should be performed anytime the user wants to verify that
the multimeter is connected properly and is responding to basic commands.
Functional Test Procedure
This test verifies that the multimeter is communicating with the command
module, external controller, and/or external terminal by performing a multimeter
self-test. You have a high confidence (90%) that the multimeter is operational if
self-test passes.
1
Verify that the multimeter and command module or system resource manager
(e.g., embedded controller) are properly installed in the mainframe.
2
Remove any input connections to the multimeter input terminals. The input
and sense terminals should be open. Errors may be induced by ac signals
present on the multimeter’s input terminals during a self-test.
3
Execute the multimeter self-test using the *TST? command.
4
A "0" returned means self-test passed with no failures. Any other value
returned is a self-test error code and means a failure was detected. See
Chapter 8 for troubleshooting information and self-test error codes.
Example: Self-Test
This BASIC example performs a multimeter self-test. Any number other than 0
returned indicates a test failure. See Chapter 8 for self-test error codes.
10 OUTPUT 70903;"*TST?"
!Send the self-test command
20 ENTER 70903;A
!Read the test result
30 PRINT A
!Display the result 40 END
If an incorrect address is used, the multimeter will not respond.
Verify proper address selection before troubleshooting.
