Freeze the measured value with
<AR>
.
The [HOLD] status indicator is displayed.
2.
Using
<ENTER>

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. Measurement
data meeting the stability control criterion is marked by AR.
You can prematurely terminate the
Stability control
function manu-
ally with
<ENTER>
at any time. If the
Stability control
function is
prematurely terminated, the current measurement data are output
to the interface without the AutoRead info.
3.
Using
<ENTER>
, start a further measurement with
Stability control
.
or
Release the frozen measured value again with
<AR>
.
The display switches to the measured value display.
The [AR][HOLD] status display disappears.
If the HOLD function is active, you can, e.g. start a manual mea-
surement with stability control.
