Manual

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
sequence. Listed below is the indexing sequence, measurement description
and example of the digital display. The display will pause at each
measurement for a few seconds in the Automatic indexing mode. In the
Manual indexing mode, tap the STEP button to advance to next
measurement.
The first column indicates what position the select switch must be in to
display that particular measurement. T is EGT, F is FF and A is ALL.
