CHAPTER 10
TROUBLESHOOTING
This chapter describes common problems, their probable causes and
remedies, and includes contact information for technical support.
Table 9 Data Validation
Problem Possible causes Action(s)
Wind measurement failure. Both
the speed and direction units are
replaced by a # sign or the data
values are irrelevant.
Blockage (trash, leaves,
branches, bird, snow, ice)
between the wind transducers.
Incorrect <cr><lf> settings in the
terminal program.
Remove the blockage, and
check that the wind transducers
are not damaged.
If the blockage is ice or snow, it
will melt after some time if
heating is enabled. Time for
clearance depends on the
severity of the weather event. If
birds are causing the blockage,
consider using the bird spike kit.
In ASCII and NMEA protocols
both <cr> and <lf> are required
after each command. Check that
your terminal program sends
both when pressing enter.
Note: The direction unit is # for
the wind speeds less than 0.05
m/s.
Pressure, humidity or
temperature measurement
failure. The unit is replaced by a
# sign or the data values are
irrelevant.
The PTU module may not be
properly connected.
There may be water in the PTU
module.
Ensure the proper connection of
the PTU module.
Remove and dry the module.
