Since memory spaces 6, 7 and 8 are occupied, this
example shows that the memory has been assigned more
than eight recordings. This means that No. 6 is the oldest
fault recording and No. 4 the most recent one.

Each memory segment has a specified storage time which
permits setting of a time prior to the trigger event.
Via the interface RS485 the data can be read and
processed by means of a PC (HTL/PL-Soft4). The data is
graphically edited and displayed. Binary tracks are
recorded as well, e.g. activation and trip.
