The EDM 960 displays engine measurements on a liquid crystal display (LCD) screen and also on a remote auxiliary display (RAD). The RAD intelligently places critical information directly in front of you. After the initial self-test, the pilot will be requested to punch in the fuel information i.e. total fuel added or fuel in the tank.

1. EDM 960 manufactured by J.P. Instruments is available four, six, seven, eight and nine-
cylinder aircraft engines configurations. The EDM 960 is designed to be a pilot’s personal
flight engineer – one that is always working in the background and constantly watching over
the aircraft engine while the pilot concentrates on flying the aircraft.
The EDM 960 actively monitors the aircraft engine four times per second and sound/ display a
warning if any part of the aircraft engine does not confirm to the pre-set parameters.
Here are the specifications of the EDM 960 Twin System manufactured by J.P. Instruments:
1. Hands-free, automatic scanning
2. All programming done from the
Front Panel
3. LeanFind™ finds the first and last
cylinder to peak with true peak
detect eliminates false peaks
4. Displays both leaned temperature
below peak and peak
5. Battery voltage with alarm

meter)
7. Programmable alarm limits
8. Normalize view
9. Exhaust Gas Temperatures (EGTs)
to stable 1°F resolution
10. DIF low to high EGT with alarm
11. EGTs to stable 1°F resolution
12. Shock cooling monitored on every
cylinder
13. User selectable index rate
14. Fast response probes

hours
17. Post-flight data retrieval
18. Download to Palm™ Computer
19. Data retrieval software
20. Oil pressure
21. Oil temperature
22. Outside air temperature
23. Fuel level
24. Adjustable display
25. Adjustable order of display

2. These are the main features of
the EDM 960 Twin System:
The EDM 960 displays engine
measurements on a liquid
crystal display (LCD) screen and
also on a remote auxiliary
display (RAD). The RAD
intelligently places critical
information directly in front of
you. After the initial self-test, the
pilot will be requested to punch
in the fuel information i.e. total
fuel added or fuel in the tank.
The RAD unit will also display the rpm and manifold pressure. The display screen is divided
into three sections – top left is for the rpm and manifold pressure. The bottom left is the
scanner section while the right side of the display is for the bar graphs.
The bar graph also displays the numerical values of each bar. If any power settings exceed
pre-programmed limits, a blinking alert icon along with a blinking message is displayed in the
scanner section.
The default displays of the EDM 960 Twin System include oil temperature, oil pressure, fuel
pressure, bus voltage amps, outside air temperature, fuel flow (left), fuel quantity and (right
side) fuel quantity.
The EDM 960 collects data and displays it for you in a useful way. The EDM 960 monitors
engine temperatures, pressures, fuel quantities, fuel flow, and voltages. It is invaluable for
adjusting the fuel air mixture and for diagnosing engine malfunctions. On the left of the
display is the EGT Probe graphed. There's also the CHT bar graph and below it the number
corresponding to the engine cylinder number.
There are four buttons on the front panel. The button labels can be changed depending on how
the display has been arranged by the pilot.

3. The features of the EDM 960 Twin includes auto indexing i.e. 10 minutes after the EDM 960
is turned on it will automatically index through all measurements.
Tapping the step button will take you into the manual indexing mode here you can observe
each measurement value for as long as you want. You can find more information here:
