Stability control
The Stability control function checks the stability of the measurement
signal. The stability has a considerable impact on the reproducibility of
measured values. The background color is red until the measured
value is stable.
Regardless of the setting for
Autom. stability control
(see page 63) in
the
System
menu, you can start the
Stability control
function manually
at any time.
Criteria
The meter checks the stability of the measured value on the basis of
the temperature measurement. For identical measurement conditions,
the following applies:
1
Highlight the channel of the conductivity measuring cell in the
measured value display.
2
If necessary, select the measured parameter with
<MODE>
.
3
Freeze the measured value with
<SC>
.
The display switches to the display of the selected channel as
necessary.
In the status line, [SC] is displayed.
4
With
<OK>
activate the
Stability control
function.
As long as the measured value does not meet the stability cri-
terion, the background color is red.
As soon as the measured value is stable, the background color
is green. The current measurement data is downloaded to the
interface. The measured values of all channels meeting the cri-
terion for stability control are marked by SC.
Note
You can terminate prematurely the
Stability control
function with
<OK>
manually at any time. If the
Stability control
function is termi-
nated prematurely, the current measurement data is not downloaded
to the interface.
5
Using
<SC>
or
<MODE>
, release the frozen measured value.
The [SC] status display disappears.
