Self-Test Procedure
Self-Test Procedure
Power-On Self-Test
Each time the instrument is powered on, a subset of self-tests are performed. This assures you that the instrument is
operational.
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. It leaves the instrument in the reset state.
User-Initiated Self-Test
The user-initiated self-test is the same as the power-on self-test.

If self-test fails, the front panel ERR indic-
