4.2.2 Measuring the ORP
The meter can, in conjunction with an ORP electrode, measure the
ORP (mV) 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.
2 Immerse the ORP electrode in the test sample.
3 If necessary, call up the measured parameter U with <M>.
4 Wait for a stable measured value.
The AR display indicator flashes as long as the measured
value is not yet stable.
