J.P. Instruments EDM 760 Pilots Guide - Manual (Page 36)

For fuel calculations to be accurate, it is imperative that you
inform the EDM-760 of the correct amount of fuel aboard the
aircraft. Do not rely on fuel flow instruments to determine fuel
levels in tanks. Refer to original fuel flow instrumentation for
primary information
Measurement Indexing—with Fuel Flow Option
The EDM-760 steps through the engine measurements in a specific
