Alignment
After mounting the WAC151 cross arm to the mast, check
that the anemometer end of the cross arm is pointing north
with the required accuracy, see Figure 5 on page 12. To
ensure correct assemblage after aligning WAC151, the
sensors can only be mounted in one way.
Verification
If the signal cable from WAC151 is connected to the data
collection system and the system is powered up, check that
the wind readings react correctly. To test the anemometer,
rotate the cups manually. To test the wind vane, hold the
vane in a few fixed angles and verify data.
