CALIBRATION
Series 5400(0)/5500(0)/56100 AccuTroll & CruiseMaster
There are nine, “Dip” switches on the back of your 5400(0)/5500(0)/56100 Series Instrument. Switches 1-4 are used for instrument
calibration (Refer to Table I). Switches 6 - 9 select the flow sensor required by your engine, (Refer to Table II) Switch 5 is used to
dampen the instrument needle in heavy seas. When turned on, switch 5 slows the needles’ response rate.
Totalizer Calibration:
1. Top off the fuel tank(s) and reset the totalizer to, “0”.
2. Operate the boat the way that you normally would, consuming at least 20 gallons of fuel.
3. Return to the fuel dock and top off your fuel tank(s).
4. Compare the totalizer reading to the fuel pump reading.
5. Calculate the percentage difference using the following formula:
Difference in Gallons
x 100
Totalizer Reading
6. Turn ON the combination of switches 1, 2 and/or 3 which equal that difference.
Example:
You determine the totalizer reading is 6.5% lower than what actually was actually used. The combined percentage total of
switches 1 (2%) and 2 (4%) is 6%. Turn switches 1 and 2 and “4” ON.
Switch #4 remains OFF if the totalizer reads higher than the actual fuel used, and is turned ON if the totalizer reading is less than
the fuel used.

* Instruments programmed for the 20A sensor cannot be used with 20B, 231 or 233C sensors.
NOTE:
1. Adjusting instrument calibration affects both Totalizer and GPH readings.
2. Drastically changing operating habits (from mostly cruising to mostly trolling) may slightly affect totalizer accuracy.
3. On custom calibration instruments, at least one of the switches from 1-5 must be OFF. If switches 1-9 are all turned
ON, the instrument automatically goes into diagnostic mode.
