At a high scan frequency and fine angular resolution, the sensor provides more measured
values with a tendency to a lower measured value quality than for a coarse angular
resolution and low scan frequency. You can estimate the achievable measured value quality
based on the following diagram.

Measured value quality as a function of scan frequency and angular resolution
How to display the current device parameters:
Scanning frequency wizard
Determine scanning frequency and angular resolution using the scanning frequency wizard.
There are two options in the scanning frequency wizard:
Choose the option A
NGULAR
RESOLUTION
and in the V
ALUE
field enter the required angle
in °.
Choose the option F
REQUENCY
and in the V
ALUE
field enter the required frequency in Hz.
Various configuration options are displayed in the next step. The recommended options
(measured value quality
7) have a green dot in the R
ECOMMENDED
column.
Recommendation
Choose the configuration that provides the highest measured value quality.
Once you have completed the wizard the new parameters will be displayed in the C
URRENT
DEVICE
PARAMETER
area.

In the LMS400 operating instructions in the section
of the chapter
“Product description”
you will find tables with the measured value qualities given by the
angular resolution and scanning frequency.
