An Overload is the condition that occurs when the signal is so high that it cannot be measured correctly with
the actual measurement equipment. An overload indicator shows when this is the case. If an overload condition appears
during a measurement this will be shown with a latching overload indicator when the measurement is finished.
The overload condition is indicated in two ways in the Nor145. The LED above the display will be red when any of
the channels is overloaded.
Additionally small triangles will be shown in the status bar at the top of the display to indicate overload in the actual channel.
