Figure 5 Suunto Compass MC-2
Compass Alignment with a Mast Adapter
The following steps aim the wind sensor when using the
1-inch adapter for mounting.
1. Use the compass to determine that the N-S transducer heads of the
ultrasonic wind sensor are exactly in line with the compass. Adjust
the heads by moving them to the left or right. For the correct
ground position of the installer, see Figure 7 on page 30.
2. If the alignment is not correct, lower the tower.
3. Loosen the clamp at the bottom of the sensor’s adapter and rotate
the sensor so that the heads marked with the N and with the S are
exactly aligned to north and south when the tower is set up. Tighten
the clamp.
4. Raise the tower to the vertical position. Figure 6 on page 29 shows
the correct alignment.
