Almanac, Environmental, and On-boat Data

Various sensors, transducers, or antennas are required to capture the data displayed on the graphs. For information about connecting the chartplotter to peripheral devices using a NMEA 2000 network, see Technical Reference for Garmin NMEA 2000 Products, on the included CD.

Configuring a Graph

You can set the scale and duration of each graph. The duration represents the time interval that appears on the graph, and the scale represents the range of the measured data that appears on the graph, including specific maximum and minimum values.

1.From the Home screen, select Information > Graphs.

2.Select a type of graph (Wind Speed, Wind Angle, Temperature, Atmo. Pressure, or Depth).

3.Select Graph Setup.

4.Complete an action:

•Select Duration, and select Up or Down to set the duration.

•Select Scale. Select Up, Down, or Auto. When you select Auto, the chartplotter sets the optimal minimum and maximum values for the range, based on environmental conditions. When the chartplotter receives new data about environmental conditions, it adjusts the scale automatically.

•Select Reset Scale to allow the chartplotter to set the optimal minimum and maximum values for the range, based on environmental conditions.

Wind Speed Data

Viewing the Wind Speed Graph

The chartplotter must be connected to the peripheral devices listed below to capture the data shown on the wind speed graph.
