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 cannot be achieved with your test sample and
electrode, you can switch over to lower reproducibility criteria. The fol-
lowing criteria can be adjusted:
z High: highest reproducibility
z Medium: medium reproducibility
z Low:lowest reproducibility
Note
Increasing reproducibility also causes the response time to increase
until a measured value is evaluated as stable.
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 terminate prematurely 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.
