Note
If the HOLD function is active, you can, e.g. start a manual measure-
ment with stability control.
Stability control
(AutoRead )
The stability control function (AutoRead) continually checks the stability
of the measurement signal. The stability has a considerable impact on
the reproducibility of measured values. The display of the measured
parameter flashes until a stable measured value is available.
You can start a measurement with Stability control manually at any
time, irrespective of the setting for automatic Stability control (see sec-
tion 4.4.3) in the System menu.
Note
You can prematurely terminate the Stability control function manually
with <MENU/ENTER> at any time. If the Stability control function is pre-
maturely terminated, the current measurement data are not output to
the interface.
