Histogram function
The histogram function counts the appearance of values within defined intervals (bins). The
number of values refers to the followings key data:
n
Distance
n
Exposure reserve
Distance
With each cycle, a measured value (distance) is recorded. The following information is avail-
able:
n
Unit
n
Start of valid range
n
End of valid range
n
Number of intervals/bins
Example:
Measurement range of the sensor: 50 - 550 mm:
n
Unit: mm
n
Start of valid range: 50 mm
n
End of valid range: 550 mm
n
Number of intervals/bins: 20
This yields:
Interval/bin covers the following range: (550 mm - 50 mm)/20 = 25 mm
If the sensor records the value 76 mm 5 times and the value 162 mm 15 times in 20 measure-
ments, the following distribution results:
Bin
Value range min.
Value range max.
