Multifunction Instrument, Totalizer Calibration
This is a four-part calibration procedure. Part I covers adjusting a Generator’s idle consumption and totalizer calibration. Part II
covers propulsion engine idle consumption, (forward and return sensor systems only). Part III helps determine the optimum fuel tank
configuration. Part IV finalizes totalizer calibration for overall accuracy.
PART I: Generators & Diesel Electric Propulsion Engines
Contact the engine dealer or refer to the engine manual-data sheet and determine the engines:
• No load fuel consumption.
• The 10 % or 25% load, fuel consumption.
Idle Consumption Adjustment for Forward and Return, Two Sensor Generator Systems
• Start and run the engine until it is at operating temperature.
• Referring to the switch diagram, rotate the Upper and Lower Black Switches to, “0”.
• With no load, verify that the engine is running at the correct RPM, (usually 1200, 1500 or 1800).
• Rotate the Lower Black switch until the GPH reading matches the manufacturer’s no load fuel consumption specification.
Totalizer Calibration for Forward and Return, Two Sensor Generator Systems
• Put a 10% or 25% load on the generator.
• Rotate the Upper Black switch until the GPH reading matches the manufacturer’s10% or 25% load fuel consumption listing.
NOTE: Generator and Auxiliary engines turning at 1200, 1500 or 1800 RPM will consume much more fuel at No Load, than
propulsion engines. If you are unable to obtain the engine manufacturer’s consumption data proceed to Part’s II and IV below. You
should triple the readings in Part II, Table 1.
PART II: Idle Consumption Adjustment for Forward and Return Sensor Propulsion Engine Systems
• Start and run engine(s) until they’re at operating temperature.
• Referring to the switch diagram, rotate the Upper and Lower Black Switches to, “0”.
• Increase engine speed to 1800 RPM for one minute. This purges any trapped air from the system.
• Return engine speed to low idle and determine its’ consumption from Table 1 below.

Lower BLACK Switch
• Rotate Lower Black Switch until the idle GPH, (LPH) reading matches engine HP from Table 1.
NOTE: At this point, idle consumption is approximate. It establishes operating parameters for final calibration. On G model
instruments, the Green Switch replaces the Lower Black Switch. G Instruments were discontinued in 1999.
