Stability control
(AutoRead )

measurement signal. The stability has a considerable impact on the reproduc-
ibility of measured values. The display of the measured parameter flashes until
a stable measured value is available.
You can start the
Stability control manually at any time, irrespective of the set-
ting for automatic Stability control (see section 11.6.3 A
