Valve Assignment..
For the selected channel:
• assign the valves to be used for the diffe
-
rent functions, (available options:
None,
V1 ... V20
)
and
•
specify the purge time for each valve (ac-
cepted values:
0 ... 10,000
s)
If there is no conflict in valve assignment, this
line shows
Yes
, otherwise check if, e.g. one
valve has been assigned different functions
for the same channel.
Note!
The purge time depends on the gas line
design and length, and is the time it takes
for the gas stream to completely fill the mea
-
suring cell, after the related valve has been
opened.
Take care, that measured concentrations are
faulty, because the cell is filled with improper
gas, if purge times are too short.
Note!
This line is available only if “Valves” in IN-
STALLED OPTIONS is set to a value other
than none. (
