Holding a program
To hold a program press F2 from the Monitor Chamber window.
The effect of holding the program will be immediately apparent as the time elapsed count
(timebase) will stop. When a program run is held the temperature and humidity levels
are controlled at the values of the calculated setpoints at the time the hold was initiated,
digital channel output status is also held as determined at that point in the program.
To remove the hold press F2 again, and the program timebase will count again from
where it was held.
