8.2  The dependency of the measuring frequency 

Since the measuring frequency is dependent on various factors, the measuring frequency is specified in the 

data sheet as a range (for example 125 ... 500 Hz). 

 

The following factors have an influence on the measuring frequency: 

- Measuring field width 

- Measuring field height 

- OBJECT setting: Bright or dark 

The measuring field height influences the measuring frequency more than the limitation of the measuring field 

width. 

 

8.2.1  Increasing the measuring frequency 

To increase the measuring frequency, the following settings can be made: 

 

Limitation of the measuring field (width) 

Limitation of the measuring field with LIMIT LEFT and LIMIT RIGHT as small as possible. 

 

 

Limitation of the measuring field (height) 

Limitation of the measuring field with AUTO H and OFFSET. 

 

 

 

 

LIMIT LEFT 

LIMIT RIGHT 

OFFSET

 

AUTO H
