[time-nuts] HP 5370B using manual start-stop

[Perry Sandeen]

List,  
I'd like to do 1000 second TIC measurements with my 5370B but I don't want to have to perchase A HP 1B prologic or similar controller for the timeing.

As long as I'm interested in the TIC difference but not an absolute value is it reasonable to use the manual start/stop switches and a stop watch or similar timer?
