Topcon A3280 installation manual Moving Compass, Recording the Weather Station Data

Weather Station Operation/Installation Manual

The following weather data will be displayed on the Guidance Status Bar:

•WS — Displays actual wind speed in mph or kph (see ‘Units’, page 9-3). The wind speed displayed is the actual wind speed. If the vehicle is moving the Guidance software takes this into account and calculates the vehicle’s GPS speed and heading direction and displays the actual wind speed.

•T — The temperature is displayed in Fahrenheit (F) or Celsius

(C) (see ‘Units’, page 9-3)

•RH — The relative humidity (%) is displayed

•DT — Delta T is displayed.

Moving Compass

When the vehicle is moving the Moving Compass is displayed on the Guidance Coverage Map screen.

Wind Direction

The ‘red arrow’ on the Moving Compass indicates the wind direction. Like wind speed the wind direction takes into account the vehicle’s GPS heading to display the actual wind direction.

Recording the Weather Station Data

For the Guidance to record the weather data with the Guidance Coverage Map the Weather Station software must be enabled (see ‘Enabling the Weather Station Software’, page 9-2).

When the Guidance is drawing the Coverage Map on the Guidance screen, then once a minute the weather data is saved automatically with the Coverage Map data, in the GDX file.
