Stability control
(AutoRead )
The stability control function (
AutoRead
) continually checks the stability of the
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
function manually at any time, irrespective of
the setting for automatic
Stability control
(see section 11.6.3) in the
System
menu.
The sensor connection and the USB-B (device) interface are gal-
vanically insulated. This facilitates interference-free measurements
also in the following cases:
Measurement in grounded test samples
Measurement with several sensors connected to one
