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.
6.1.2 Measuring the temperature
For reproducible ORP measurements, it is essential to measure the tempera-
ture of the test sample.
When operating a sensor without integrated temperature sensor, you first have
to measure and enter the temperature of the sample.
The measuring instrument recognizes whether a suitable sensor is connected
and automatically switches on the temperature measurement.
The display of the temperature indicates the active temperature measuring
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 are 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.
