Underdeviation and overdeviation
Underdeviation and overdeviation parameters are useful when it is important to avoid, for example,
having sustained undervoltages being cancelled in data by sustained overvoltages. Results can be seen
in a tabular (METER) or a graphical form (TREND) view - which is active only while GENERAL RECORDER
is active. See section 3.14 for instructions how to start recording. In order to understand meanings of
