Garmin 7212 Manuale Utente

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.

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 

 > 

.

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

Select 

 to allow the chartplotter to set the optimal minimum and maximum values 

for the range, based on environmental conditions.

The chartplotter must be connected to the peripheral devices listed below to capture the data shown 

on the wind speed graph.

Apparent Wind Shows wind speed data based on the flow of 

air experienced while on a boat in motion.

A wind sensor.

True Wind

Shows wind speed data based on the flow of 

air experienced while on a stationary boat. 

For the most accurate data, the Wind Speed 

Source setting should be set to Auto

  

A wind sensor and a speed sensor; or a wind 

sensor and a GPS antenna.

Ground Wind Shows wind speed data based on the flow of 

air experienced while on shore.

A wind sensor, a water-speed sensor, a 

heading sensor, and a GPS antenna; or a 

wind sensor and a GPS antenna; or a wind 

sensor, a water-speed sensor, and a heading 

sensor.

1.  From the Home screen, select 

 > 

 > 

.

2.  Select the type of wind speed data included on the graph (Apparent Wind, true Wind, or
