Measuring
6.1.1 Measuring the ORP
When connecting an earthed PC, measurements cannot be performed in
earthed media as the values would be incorrect.
The USB interface is not galvanically isolated.
Stability control
(AutoRead )
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.
You can activate or switch off the automatic
Stability control
function (see
The measured parameter flashes on the display
as soon as the measured value is outside the stability range
when you switch over between the measured parameters with
<M>
.
when the automatic
Stability control
is switched off.
Criteria for a stable
measured value
The
Stability control
function checks whether the measured values are stable
within the monitored time interval.
1.
Connect the ORP electrode to the meter.
2.
If necessary, select the mV display with
<M>
.
3.
When measuring without temperature sensor:
Measure the temperature of the test sample and enter it with
<
> <
>
.
4.
Immerse the ORP electrode in the test sample.
The measured value is checked for stability (automatic stability control).
The display of the measured parameter flashes.
5.
Wait for a stable measured value.
The display of the measured parameter no longer flashes.
