The cell on/off at the end of the experiment is controlled in the Advanced/Expert options of the experimental setup.  You can set it such that the cell is on at the end of the experiment.  When the next experiment starts, the cell should not go off unless you have requested it to measure the open- circuit potential.  If instructed to measure the open-circuit potential, the cell must go off to make this measurement.  Otherwise, set the parameter in the Pre-scan options to "use previous measured oc."
