Setting the Water Temperature Offset
You must have a water-temperature sensor or a temperature-capable transducer.
The temperature offset compensates for the temperature reading from a temperature sensor.
1. Measure the water temperature using the temperature sensor or temperature-capable transducer
that is connected to the chartplotter.
2. Measure the water temperature using a different temperature sensor or thermometer that is known
to be accurate.
3. Subtract the water temperature measured in step 1 from the water temperature measured in
step 2.
This is the temperature offset. Enter this value in step 5 as a positive number if the sensor
connected to the chartplotter measures the water temperature as being colder than it actually
is. Enter this value in step 5 as a negative number if the sensor connected to the chartplotter
measures the water temperature as being warmer than it actually is.
4. From the Home screen, select Configure > My Boat > temp offset .
5. Enter the temperature offset calculated in step 3:
For the GPSMAP 6000 series, use the Rocker or the Numeric Keypad to enter the
temperature offset.
For the GPSMAP 7000 series, use the on-screen keyboard to enter the temperature offset.
6. Select Done .
