PMAX PIT MAXIMUM
Description
Pit Maximum provides a measurement of the maximum voltage value of pits of interest. It
provides a comparison of how the maximum point in the waveform corresponds to the ptop value
When pmax is configured as a custom parameter, all maximums within the single nT or range of
nT are calculated. Histogramming or trending such a configuration would result in one value per
pit in the nT range contributing a value to the histogram or trend. The value displayed on the
custom parameter display line is the average of all such maximum calculations. ‘nT Table’ mode
provides an average maximum value for the pits in each n index.
Display Options
ORM parameter calculations can be displayed, histogrammed and trended in a variety of ways.
The table provides a concise description of the value or values displayed using each approach.
DISPLAY TYPE VALUE DISPLAYED
Parameter Statistics Off
All values of the maximum for all pits within the selected ‘nT’
range for the last acquisition.
Parameter Statistics On
Average, minimum, maximum, and sigma of the maximum for
all pits that are within the selected ‘nT’ range for all acquisitions
since the last C

nT Table
List of values of the average maximum for each group of pits of
common ‘nT’ width for the last acquisition.
Histogram Function
Histogram graph of the value of the maximum for all pits within
the selected ‘nT’ range for all acquisitions since the last C
