NOTE
•
The device outputs the data after the start of the measurement through the same
interface via which the measured values were requested.
•
It is only possible to output all measured values of a scan in real time using the
Ethernet interface.

Interlaced mode
Interlaced mode is available for LMS5xx PRO/Heavy Duty only.
With Interlaced mode, measurement data can be acquired with a fine angular resolu‐
tion even at high scanning frequencies. Recurring sequences of scans are generated.
The first scan of a sequence is a normal scan. In the following scan, the start angle
is offset by a proportional angle increment so that the measuring points are placed
in the gaps of the first scan. By combining the individual scans of a sequence, the
measurement data is ultimately available with the finer angular resolution.

Setting of Interlaced mode
•
By telegram: Separate activation of Interlaced mode is not necessary. With the
mLMPsetscancfg
telegram, Interlaced modes can also be selected by using valid
values of an Interlaced mode as parameters for scanning frequency and angular
resolution. The device will automatically scan in Interlaced mode if necessary. The
scans are otherwise output directly without an interlaced sequence.
•
SOPAS ET: In the
Defaults
menu, interlaced modes can also be selected as scan
configurations.
NOTE
For interlaced scan configuration, the particle filter must be deactivated.
