12. set in the range of 1 to 99 seconds Description Normally engines do not draw fuel from the tank at a constant rate Instead they draw fuel at a high rate for a short time until the carburetor bowl or injection reservoir is full and then draw no fuel for a few seconds If the true flow rate were displayed it would be too erratic to read Usually a value of 10 15 seconds will give satisfactory results for two stroke naturally carburetor engines Four stroke engines that use an electronic fuel injection may require longer periods If the reading seems erratic you can increase the period A large number means the fuel flow display will have a slow response time but more accurate average readings and a short period means the display will have a quick response time and erratic display readings The flow period setting only affects the fuel flow display It does not affect the fuel used or fuel remaining measurement in terms of accuracy Flow Average menu Enter the flow averaging menu 1 While holding the up button power up the unit by turning on the ignition key 2 Press and hold both the up and down buttons together for two 2 seconds to enter fuel flow average mode ay 7 3 The fuel flow average period menu AVG is displayed briefly and the default value of 10 seconds is displayed if you have not previously changed it 4 Use the up or down button to select a new value between 1 and 99 seconds
13. ur boat does not have a flexible fuel hose and is fitted with a metal fuel line or fuel line other than the US Coast Guard 3 8 9 5 mm a section of 3 8 9 5 mm must be fitted between the fuel transducer and the existing fuel lines Consult an Engine Specialist for professional advice to ensure the various fuel line connection are correctly made Always ensure that the hose on either side of the transducer is clamped to the hull or similar rigid structure to minimize vibration Mounting hardware is NOT supplied After selecting a suitable location cut the fuel line and using the fuel hose attaching clips provided install the transducer so that the FUEL IN side of the transducer connects to the fuel tank UP to Shield Fuel White Manager Black Fuel Flow Transducer Fuel Flow Clamp to Hull or simular rigid structure Transducer must sit above the maximum fuel level 3 8 9 5 MM Description The Fuel Manager is a device that shows the amount of fuel used by measuring the amount of fuel passed through a transducer and averages that flow to give an estimate of the fuel used while operating your boat You can learn more about this averaging on page 7 The Fuel Manager is designed for ease of use There are two buttons S FLOW TOTAL z Pressing the up button will show you the Rate of Flow through the transducer O Pressing the down button allows the user to select the function
