PEAK: The absolute highest sample that occurs during the measu-
rement sequence is stored as the PEAK value.
MIN: Analogous to PEAK the absolute lowest sample value is u-
sed to form the MIN value.
For the computation of the HIGH, LOW, AVERage and RMS values a
imaginary „change level“ is used representing the middle
between the PEAK value and the MIN value. This „change
level“ is used to detect the beginnings and the ends of sig-
nal periods and the change between high and low frag-
ments of the signal course.
NOTE:
The pulse analysis for the HIGH, LOW, AVERage and RMS values
delivers correct results only for periodical signals.
HIGH: For the HIGH value the average of all samples with values
higher than the change level is formed and stored.
LOW: For the LOW value the average of all samples with values
lower than the change level is formed and stored.
AVER: For the computation of the AVERage value only complete
recorded signal periods are considered and the average of
all samples belonging to this periods is formed and stored.
RMS: For the computation of the RMS value only complete recor-
ded signal periods are considered and the square average
of all samples belonging to this periods is formed and sto-
red.
