Stability control
(AutoRead)
& HOLD function
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 measured parameter flashes on the display
as soon as the measured value is outside the stability range
when the automatic
Stability control
is switched off.
You can activate or switch off the automatic
Stability control
function (see
Criteria
The AutoRead criteria affect the reproducibility of the measured values. The
following criteria can be adjusted:
high
: highest reproducibility
medium
: medium reproducibility
low
: lowest reproducibility
1.
Freeze the measured value with
<AR>
.
The [HOLD] status indicator is displayed.
The HOLD function is active.
You can terminate the
Stability control
function and the HOLD func-
tion with
<AR>
or
<M>
at any time.
2.
Using
<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 mea-
sured 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>
or
<M>
.
The [AR] status display disappears. The display switches back to the
previous indication.
