Available in "Sample measurement mode" (see Instrument configuration on page 52), this setting
allows configuration of the stop criteria for each channel:
Above threshold: The stop criteria is met when the gas concentration is greater than the parameter
entered in "Threshold"
Below threshold: The stop criteria is met when the gas concentration is lower than the parameter
entered in "Threshold"
Stability: The stop criteria is met when the variation of the gas concentration is smaller than the
parameter entered in "Variation"
Time: The stop criteria is met when the elapsed time reaches the "Max. time" parameter.
The parameter "Max. time" is the maximum time allowed to reach the target. If "Time" is not the type
of stop criteria, then when this delay has elapsed, the measurement stops and the message
"aborted" is displayed.
The time filter allows you to filter the stop criteria. The sample mode is stopped when the stop criteria
is fulfilled for a time greater than the parameter "Time Filter".
As an example, if criteria is set to "Above threshold" and "Time Filter" is set to 10 sec. the
measurement stops when the gas concentration is above the "Threshold" for more than 10 seconds.
