Displaying the Width of the Sensing Object: One-point Scaling B
The width of the sensing object can be measured by using two-sensor
operation and one-point scaling, and inverting the display values.
First, perform the two-sensor operation A+B to display the sum of the mea-
sured values for the two Sensor Heads.
Refer to 3-8-7 Two-sensor Operation.
Second, set the actual sensing object and set the values to be displayed in
scaling mode.
When selecting the incident level display (L) for auto-scaling, enable invert-
ing display values for the scaling mode so that smaller values are dis-
played when larger intercepted beam widths are measured at the Sensor
Head (i.e., when thinner intercepted beam widths are measured).
When the widths of two sensing objects are known, two-point scaling can
also be used.
Example: One-point Scaling B
