and that during the detectable time interval defined as:
 32 x 5s = 160s.
 32 x 78s = 2.5ms.
 32 x 65s = 2.1ms.
the positive and negative difference (defined DELTA+ and DELTA- respectively) it’s over
the “windows” defined by the limit threshold set by user.
Based to the above description, downloading the saved data from meter to PC using the
standard TopView software, the below parameters are shown:
 Num. Tot  Total number of recorded events.
 Limit  Voltage value threshold defined by user which permits the recording
of a event.
 Phase  ID of phase where the event is occurred.
 Date/Time  Date/Hour in minutes, seconds, cents per second when the event is
occurred.
 Up/Down  This flag is UP if the spike is correspondent to a rising edge and is
DOWN if the spike is correspondent to a falling edge.
 PEAK+  Max positive value reached from spike during the detectable time
interval.
 PEAK-  Mix negative value reached from spike during the detectable time
interval.
 DELTA+  Max positive relative difference reached from spike during the
detectable time interval.
 DELTA-  Min negative relative difference reached from spike during the
detectable time interval.
 F/S  Type of event (F = FAST, S = SLOW).
