Measuring the ORP
Note
ORP electrodes are not calibrated. However, you can check ORP
electrodes using a test solution.
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 display of the measured parameter flashes until
a stable measured value is available.
Independent of the setting for automatic
Stability control
in the
System
menu, you can start the
Stability control
function
manually at any time.
Note
You can terminate prematurely the
Stability control
function with
<MENU/OK>
manually at any time. If the
Stability control
function is

The display switches to the display of the selected channel as
necessary.
In the status line, [SC] is displayed.

With
<MENU/OK>
activate the
Stability control
function.
[SC] flashes while the stability control is active.
As soon as a stable measured value is recognized, the current
measurement data is downloaded to the interface. The
measured values of all channels meeting the criterion for
stability control are marked by SC.
