TROUBLESHOOTING

This chapter describes common problems, their probable causes and

remedies, and includes contact information for technical support.

Table 9 Data Validation

Problem Interpretation Action

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.
