Attach the masthead bracket with the screws provided. Ensure
the bracket is mounted the right way round, so that the wand
will be pointing in the correct direction (Fig 4.9). The transduc-
er can be mounted facing aft if required, but it will be neces-
sary to set the transducer orientation to AFT in the calibration
menu (see Section 3.2 for more details).
4.2.3 Assembling the Transducer
The vane and cups assemblies are packed separately - fit the
vane to the transducer so that the shaft on the top of the trans-
ducer fits correctly into the vane (the shaft is keyed so that it
will be aligned correctly). Screw the counterweight in just far
enough to lock the vane into place (Fig 4.10) -
NOTE Check that the vane rotates freely - do not overtighten the
counterweight or it may restrict the vane’s movement.
The anemometer cups fit to the base of the transducer body in
a similar way (Fig 4.11). Once fitted, they are held in place by
a grub screw, which should be tightened (using the allen key
supplied) enough to hold the cups in place without restricting
their movement.
