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.
