Deltas measure the difference between two ROIs that have the largest temperature difference in a group of two or more ROIs.
The delta is calculated by subtracting the lowest maximum temperature from the highest maximum temperature of a set of ROIs
selected. You can set alarm conditions on deltas to monitor when the difference between ROI temperatures exceeds the value
Complete the following steps to configure an ROI Delta.
