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 indicators, and voltages.
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

24. Adjustable display
25. Adjustable order of display
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 Temp Probes, 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 indicators, 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 Probes 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.
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.
