4.2.2 Measuring the ORP voltage
In conjunction with an ORP electrode, e.g. SenTix ORP, the measuring
instrument can measure the ORP voltage (U) of a solution.
Note
ORP electrodes are not calibrated. However, you can check ORP elec-
trodes using a test solution.
1 Perform the preparatory activities according to section 4.2.
2 Immerse the ORP electrode in the test sample.
3 Press the <M> key until U appears on the status display.
The ORP voltage (mV) of the sample appears on the display.
4 Wait for a stable measured value.
