412HP AFCS checks

I'm new to the HP and have a question on testing the AFCS. (I've only done the automated test before) From the flight manual...

Cyclic ATTD TRIM switch - Right for 2 seconds, then aft for 2 seconds. Observe APIs move right, up.
SYS 2 button - Depress and hold.
Observe SYS 2 actuators agree.
Cyclic FORCE TRIM release button -
Depress. Observe APIs move to center.

When you use the ATTD TRIM on the ground during this test would you expect the cyclic to move in response to the trim input?

If it should move would you expect the cyclic to move immediately or with a delay?

Should it stop moving once the trim input has been released or continue motoring towards the stop?

Trying to troubleshoot a finicky AFCS and based on my experience on newer 412's I expected the cyclic to move, but it is not described that way in the flight or maintenance manual.

Thanks.
