generated at the moment of the last two executions of the VA track called
by CALL COND.
A standard deviation of around 2% is to be recommended for small sig-
nals (< 500
μC) and a value of around 0.5% for larger signals (> 500 μC).
Input range 0.1 - 99.9 %
Default value 0.5 %
Example: measuring command with 2 measurement cycles (replications)
The following single results x-y of run x and replication y will be used for
the calculation of the standard deviation:
After 2 runs: 1-1, 1-2, 2-1, 2-2
After 3 runs: 2-1, 2-2, 3-1, 3-2
After 4 runs: 3-1, 3-2, 4-1, 4-2
etc.
The current values (peak areas or peak heights) are displayed on the work-
place in the table of the Curve subwindow during conditioning. The cur-
rent relative standard deviation of the conditioning is displayed on the
workplace in the table of the Curve subwindow starting with the second
run of a CALL COND command.
This applies only if the Evaluation quantity stop criterion is activated in
the CALL COND command.
Number of runs
on | off (Default value: off)
If this check box is activated, then the defined action is triggered when
the specified number of runs of the VA track has been achieved.
Number of runs
Number of runs of the VA track, after which the call of the VA track is to
be canceled.
Input range 0 - 999
Default value 20
Action
Definition of the action that is to be executed if this stop criterion is ful-
filled.
