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.
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.

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
section 7.1.1 C
HANGING THE SETTINGS FOR P
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.
The Stability control function checks whether the measured values are stable
within the monitored time interval.
