Enter the minimum time period that
the concentration and transmission
must be stable for. The minimum
stability time is 30 sec.
15
Enter the flush time. During the
validation process, when validation
gas is applied, the analyzer will wait
for this length of time before
attempting to calculate
measurement stability. The flush
time should take into account factors
such as the length of pipework
between the gas bottle and the
validation cell. The minimum flush
time is 30 sec.
A flush time of 2 min should be
sufficient for most applications.
16 Enter a timeout value. The analyzer
will use this timeout when waiting for
the measurement to achieve
stability. In the example of the
picture, if each validation condition is
not fulfilled within a 10 min period,
the analyzer would exit the validation
procedure.
17 Enter the Low Signal Threshold for
validation. This should be high
enough to ensure that validation is
performed in low signal mode.
250000 is the default value and
should be ok for most applications.
18 It is possible to apply a constant
scaling factor to the span
measurement. Enter the scaling
factor here. If no scaling is required,
the scaling factor should be 1.0.
Note: scaling factors are only
effective for pathlength <1.0 m.
