Self-Test Procedure
Power-On Self-Test
Each time the instrument is powered on, a self-test is performed. This test 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.
