After mounting the WAC155 transmitter to the mast, make sure that the WAV151 end of the cross arm is pointing to the North.

If you cannot align the cross arm wind vane end directly to the North, you can measure the deviation angle and set the value of wind direction angle offset with the SETDIR command. See SETDIR.

When the cross arm deviates from the North in the clockwise direction, use the plus sign (+) in the offset parameter. For counterclockwise deviation, use the minus sign (-).

Wind direction can be referred to true North, which uses the Earth's geographic meridians, or to magnetic North, which is read with a magnetic compass. The magnetic declination is the difference in degrees between the true North and magnetic North.
