5.2 Visual inspections and cleaning work
The use of the sensor under the respective environmental conditions requires certain actions. It is thus
recommendable to clean the outside of the housing and shelter within specific intervals. The intervals are dependant
on the environmental conditions and the degree of soiling. We recommend a regular visual and functional check.
In case you should be faced with any specific problems, which you are unable to solve, please contact the
LAMBRECHT meteo service:

6 Transports
In case it is necessary for you to ship or transport the sensor, it must be carefully packed to prevent damages during
transport.

Data protocols
DATA PROTOCOL WIMWV
WIND DIRECTION AND WIND SPEED
Example of a data sequence with comma seperatd fields:
$WIMWV,357.0,R,5.2,M,A*CS<CR><LF>
Field delimiter: , (comma)
Header: $WIMWV
Wind direction (WD): 0.0 to 360.0
R: relative wind direction
Wind speed (WS): 0.3 to 75.0
M: metric unit in m/s
Status A (valid) / V (invalid)
Stop delimiters: <CR> <LF>
Error code: WR 999.9
Error code: WG 99.9
NOTE:
In the development of a NMEA decoder fixed field lengths should not be assumed. The NMEA definition is based
on a variable field length. The comma character (‘,’) serves as a field separator. Numerical values in a field can be
represented in different ways.
If a field is not sent, it has a length of 0 characters (,,).
The check sum „CS“ is output as a 2 character hexadecimal value. All characters in the data sequence between „$“
and „*“, but excluding „$“ and „*“ are calculated as XOR function.
<CR>...carriage return (hex0D),
<LF>... linefeed (hex 0A)
Further protocols available on request.
