9.1 Control Valves Check Routine
The measuring instrument Check Routine function allows checking forcing gas pressure
and control valves operation. Select
CHECK ROUTINE
from the
OPTIONS
menu, then
select
ABC check
or
D check
. The measuring instrument will run the corresponding
test. Results are sent as error messages in the OrbiPack software window.
Note:
All control valves in the system are of the normally closed type, so they are open when
activated.
