Criteria The criteria of the stability control affect the reproducibility of the mea-
sured values.
If possible, always use the highest reproducibility criteria.
If the stability criteria are not met with your test sample and electrode,
you can change to lower reproducibility criteria. The following criteria
can be adjusted:

High : highest reproducibility

Medium : medium reproducibility

Low : lowest reproducibility
Note
With increasing reproducibility, the time until a measured value is eval-
uated as stable is longer.
4 With <OK> activate the Stability control function.
While the measured value does not meet the stability criterion,
the background color is red.
As soon as a stable measured value is recognized, the current
measurement data is downloaded to the interface. The mea-
sured values of all channels meeting the criterion for stability
control are marked by SC.
Note
You can prematurely terminate the Stability control function with
<OK> manually at any time. If the Stability control function is termi-
nated prematurely, the current measurement data is not downloaded
to the interface.
5 Using <SC> or <MODE> , release the frozen measured value.
The [SC] status display disappears.
