Open Circuit Voltage (OCV) is the same as Open Circuit Potential (OCP). This is the potential where no current is flowing, because the circuit is open.

In this section the reasons for choosing a certain DC potential is explained. The advantages of using Ecorr as a reference point will be presented as well as how to choose in PSTrace to use potentials versus the reference electrode or versus Ecorr.
In this chapter the Open Circuit Potential (OCP) and the Corrosion Potential are introduced. The principles of reference electrodes as well as the 0 V by convention potential of the standard hydrogen electrode (SHE) are explained.
The multiplexer MUX8-R2 offers the possibility to record reliable Open Circuit Potential (OCP) measurements in the Alternating mode, which allows to monitor the OCP of multiple samples / working electrodes over time with a single potentiostat. This is a significant improvement compared to its predecessors MUX8 and MUX16. In this application note it is demonstrated how to setup and perform an OCP measurement with the MUX8-R2 in the Alternating mode.
