HISTOGRAM
–.Output.of.histograms
The
HISTOGRAM
menu is divided into 2 parts:
1.
..Outputting.the.histograms
for
POS class
(dwell time density) and
DIR class
(movement range)
2.
List.of.the.characteristic.values
for
CMD Set-point position valve actuator
POS Actual position valve actuator
DEV Deviation from POS to CMD
TEMP Temperature
SP Process set-point value
PV Process actual value

Path covered by the actuator
10 histogram bars, each of which represents 10 % of the total stroke:
Bar on left = class 1 (0 - 10 %)
Bar on right = class 10 (91 - 100 %)
