If  yours is like my Heathkit IT-11, then the eye should stay open.   
There is no mention of how long to observe the "eye".  The eye will  take 
longer to open while charging larger value caps.  If the eye  does not 
fully open or starts blinking at you, then it is bad.   Electrolytic 
testing is a different story.
