3.8.2 Reduction in Measurement Time to as Little as 30ms
Definition of uniqueness range
Due to the periodicity of the sinusoid, the phasing of the signals received by the ODSL 30
limits the determination of unique measurement values to within a specific interval. The
length of this interval is called the uniqueness range. A large uniqueness range is equivalent
to high background suppression.
Relationship between uniqueness range - luminosity coefficient - measurement
time
In the default setting (uniqueness range 150m, measurement on both light as well as dark
objects with luminosity coefficients of 6 … 90%), the measurement time is 100ms.
By limiting the uniqueness range and the luminosity coefficient (measurements on only light
objects with luminosity coefficients of 50 … 90%), the measurement time can be reduced to
as little as 30ms.
Configuration is performed using the keypad and display:
Applic. Param. -> Tmeas Bgnd Rem.
Changes to these variables yield measurement times as shown in the following table:
Notice!
By using the cooperative target CTS 100x100 (Part No. 501 04599), you ensure that the lu-
minosity coefficient on the surface being measured is 50 … 90%.
Attention!
If an object is located at a distance greater than the preselected uniqueness range, incorrect
measurements will result (provided the reception signal is sufficiently high)!
