GPSMAP® 6000/7000 Series Owner’s Manual 07SonarSetting the Water Temperature OffsetYou 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 transducerthat is connected to the chartplotter.2. Measure the water temperature using a different temperature sensor or thermometer that is knownto be accurate.3. Subtract the water temperature measured in step 1 from the water temperature measured instep 2.This is the temperature offset. Enter this value in step 5 as a positive number if the sensorconnected to the chartplotter measures the water temperature as being colder than it actuallyis. Enter this value in step 5 as a negative number if the sensor connected to the chartplottermeasures the water temperature as being warmer than it actually is.4.
