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 the
Stability control
manually at any time, irrespective of
the setting for automatic
Stability control
(see page 34) 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.
Criteria for a stable
measured value
The
Stability control
function checks whether the measured values are
stable within the monitored time interval.
The minimum duration until a measured value is assessed as stable is
the monitored time interval. The actual duration is mostly longer.
3
Select the mV display with
<M>
.
1
Freeze the measured value with
<AR>
.
The [HOLD] status indicator is displayed.
2
Using
<MENU/ENTER>
, activate the
Stability control
function
manually.
The [AR] status indicator appears while the measured value is
assessed as not stable. A progress bar is displayed and the
display of the measured parameter flashes.
The [HOLD][AR] status indicator appears as soon as a stable
measured value is recognized. The progress bar disappears
and the display of the measured parameter stops flashing.
The current measurement data is output to the interface. Mea-
surement data meeting the stability control criterion is marked
by AR.
3
Release the frozen measured value again with
<AR>
or
<M>
.
The [AR] status display disappears. The display switches back
to the previous indication.
