4.2.3 Measuring the ORP voltage
In conjunction with an ORP electrode, e.g. BlueLine 31Rx, the measuring in-
strument can measure the ORP voltage (U) of a solution.
Note
ORP electrodes are not calibrated. However, you can check ORP electrodes
using a test solution.
1 Perform the preparatory activities according to section 4.2.1.
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 test sample appears on the dis-
play.
4 Wait for a stable measured value.
