9.9.21 Defining the Scaling Factor for the Measuring Value Output
\ Scaling \ Physical Unit
In the operating mode CCD CAM 100, the Physical Unit menu is
used to define the scaling factor for the output of the measured
values in µm. By converting the scaling factor, you can reduce the
size of the numerical value output by a factor of 10.
Fig.112: Physical Unit menu
Example
16,000 pixels (400 mm)
measured sample width
Camera resolution
e.g. 0.04 pixels/µm
Operating mode CCD CAM 100
(DIL switch S1.1 and S1.2 = OFF)
Fig.113: Example
Measured
sample width [pixel]
16,000 pixels
Camera resolution 0.04 pixels/µm
Calculated
sample width [µm]
16,000 pixels: 0.04 pixels/µm = 400,000 µm
Depending on the unit selected in the Physical Unit menu, the
following numerical values result for the output of the measured
values:
Unit Numeric value output
Pixel 16,000
µm 400,000
10µm 40,000
Switching between the units Pixel and µm is carried out using DIL
switch S1.4 (see Setting DIL Switch S1, page 74).
