Total Fuel Rate – displays rate of fuel usage per unit time (for example, gallons or liters per hour) for all engine instances specified within the favorite screen setup (see Section 5.2.6.4.2 for details)

Total Fuel Remaining – displays total fuel remaining in all fuel tanks specified within the favorite screen setup (see Section 5.2.6.4.2. In order for the DSM250 to properly calculate total fuel remaining, tank monitors connected to the network must provide tank capacity in addition to fluid level.

Distance to Empty – displays the distance you can travel before all fuel is consumed, assuming all conditions remain the same. The DSM250 computes distance to empty using several different parameters including the total fuel remaining (see above) and fuel economy (also discussed above). Remember, conditions can rapidly change that may drastically effect distance to empty. For example, if you are going out to sea with the wind and current behind you, the distance to empty may indicate that there is enough fuel to return home when in fact there isn’t enough fuel to return. Distance to empty is only applicable if the conditions remain the same.

Time to Empty – displays the amount of time you can travel before all fuel is consumed, assuming all conditions remain the same. The DSM250 computes time to empty using total fuel remaining (see above) and the engine(s) fuel rate. Remember, conditions can rapidly change that may drastically effect time to empty. For example, if you are going out to sea with the wind and current behind you, the time to empty may indicate that there is enough fuel to return home when in fact there isn’t enough fuel to return. Time to empty is only applicable if the conditions remain the same.

Total Fuel Capacity – displays the total capacity of all fuel tanks. The DSM250 can only compute total fuel capacity assuming all totalized tanks are transmitting their capacity.

Total Fuel Level – displays the percentage of fuel remaining in all fuel tanks.

Total Fuel Consumption – displays the total volume of fuel used per unit of distance traveled (for example, gallons per mile or liters per km) using the specified GPS and specified engine instances within the favorite screen setup (see Section 5.2.6.4.2 for details).

4.2.12GPS

Course Over Ground – displays the current Course over Ground (either true or magnetic depending on the “Heading:” setting found under the “Units…” menu item)

Lat/Lon – displays the current latitude and longitude of the vessel Speed Over Ground – displays the current speed over ground

Status – displays the current operating mode and status of the specified GPS receiver

4.2.13Heading

Magnetic/True – displays the current heading of the vessel (the direction the vessel is pointing) relative to true or magnetic north depending on the unit setting of the heading parameter (see Section 5.2.7.1)

Rate of Turn – displays the angular rate of rotation of the vessel about the vertical axis Variation – displays the magnetic variation used to convert between true and magnetic headings

4.2.14Humidity

Inside – displays the relative humidity from an indoor humidity sensor

Outside – displays the relative humidity from an outdoor humidity sensor
