	2) OVI detector turn on, OVI Stimulus Pulse Test conducted, HV ramped up 
   
	Sequence: Manual, TakeOVI_TxN 120 2 

	SCI_SPEC: After switching off LyA detector, the OVI detector is turned on
		  a stimulus pulse test is completed

		  After powering on OVI detector, discriminator settings were discovered
		  to be incorrect. Discriminator settings were commanded to their nominal
		  values.
