6.8 Automatic stability control
The Autom. stability control function continuously checks the stability of
the measurement signal. The stability has a considerable impact on the
reproducibility of measured values.
You can activate or switch off the Autom. stability control function
(menu, Autom. stability controlSystem).
The Autom. stability control function is carried out:
 as soon as the measured value is outside the allowed stability range
 when you switch over between the measured parameters with
<MODE>.
Whether or not a measured value is stable can be taken from its color
labeling.
In the delivery condition, the SC stable / SC not stable conditions are
assigned to the following colors:
Color Meaning
red SC not stable
Stability criteria not met
green SC stable
Stability criteria met
SC stable
SC not stable
