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.
