| remove the counter electrode, measure the voltage between the working electrode and reference electrode with a voltage meter, just for the testing, to see the OCP |

in principle, for a potentiostat, three electrodes system, the counter electrode is used for the current circuit, the potential of working electrode is measure use a reference electrode as a reference. because we just can measure a voltage between two electrodes, can not measure anyone of them. For the case of OCP, the current is zero, it means not current flow. so we don't need the counter electrode. a multimeter, with very high resisitant, 10M ohm, maybe, if the voltage is 1V. the current is 0.1mA, very low, is equal to OCP. then you can exclude the effect of current, not corrision will be seen |

I just wonder are you an expert in this area? |
