6.1.1 Measuring the ORP

NOTE
When connecting a grounded PC/printer, measurements cannot be
performed in grounded media as the values would be incorrect. The USB
interface is not galvanically isolated.
IDS ORP sensors are not calibrated. However, you can check IDS
ORP sensors using a test solution.
1. Connect the ORP sensor to the meter.
The ORP measuring window is displayed.
2. Adjust the temperature of the solutions and measure the current tem-
perature.
3. Check the meter with the ORP sensor.
4. Immerse the ORP sensor in the test sample.

Info
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.
The measured parameter flashes on the display
 as soon as the measured value is outside the stability range
 when the automatic Stability control is switched off.
You can start the Stability control manually at any time, irrespective of the set-
ting for automatic Stability control (see section 9.5.3 A
, page 69) in the System menu.
