Power-off in-circuit test

Power-off in-circuit test (ICT). Typically, test programs are written such that the test is aborted if any power-off faults are detected.

Apply board power and check critical voltage points including behavior of powered components such as operational amplifiers.

Perform more extensive functional testing such as checking input/output parameters.

Solid-state switching in 200-point increments and 50-point relay switch matrix cards may be mixed in any combination.
