EDM-930 Primary Display TSO'd/STC'd/Experimental

Our flagship EDM930 has been redesigned to fit more ways in your panel! It can be mounted directly into a standard 3.1″ hole or flush-mounted. Our Primary system allows you to remove your old steam gauge engine instruments and move up to the most advanced and accurate piston engine monitoring instrument on the market. The EDM930 also features a long list of user options. EDM-930 as your personal flight engineer. Always there, working in the background, constantly watching over your engine while you concentrate on flying the aircraft. Your EDM-930 will be monitoring your engine conditions four times per second and will warn you instantly if any measurement exceeds the programmed limit.

Leaning is accomplished quickly and automatically using the LeanFind™ procedure. With the EDM it is now possible to have substantially more diagnostic information available to you in a timely and usable manner.

The EDM 930 collects data and displays it for you in a useful way. You can use the EDM 930 to monitor engine temperatures and voltages, adjust the fuel/air mixture, and diagnose engine malfunctions.

The EDM 930 is a self contained instrument. All functions or channels on the EDM are recorded at an adjustable rate of every 2 to 60 seconds per recording. The EDM-930 is sold in several versions.The display is a TFT, full VGA not 1/4 VGA display. This type of display permits a lot of latitude in placing the gages on the screen. The EDM-930 is sold in several versions.

Accuracy and Resolution, are two of the most misunderstood terms in instrumentation. Because an instrument displays 1 degree increments (resolution) does not mean it is accurate to 1 degree. JPI’s accuracy comes from its linearized thermocouples. Other’ put and estimating straight line through the center of the thermocouple calibration “S” curve. With this method the instrument is accurate at only three points along as the the straight line crosses the “S” curve. Therefore errors of +/- 10′ are quite possible while still displaying in 1degree resolution. Our competition is advertising +/- 1/2′ accuracy at full scale. This would mean that =/-1/2′ of 2000′ (full scale) is +/- 10′; there is a big difference. JPI has found nothing in the Aviation market that compares to our linearized accuracy.
