If the Current IT checkbox is not marked, the scan automatically reverses at Potential EV. If the Current IT box is marked, the scan reverses when the current exceeds Current IT, but only after the potential has scanned past Potential EV. If Current IT is reached before Potential EV, the scan reverses at Potential EV if the current still exceeds the threshold.
