Overview of the EDM 700 System

The Engine Data management 700 system is one of the accurate and advanced piston engine- monitoring devices in the market. The EDM 700 System uses latest microprocessor technology to monitor up to 24 critical parameters in any at a speed of four times per second in line with thermocouple having an accuracy of more than 0.1 percent or of 2 F.

The EDM 700 System is capable of collecting data and displaying it in a more useful manner. It is used for monitoring voltages and temperatures, adjusting air/fuel mixture and diagnosing engine malfunctions.

The EDM 700 System is also capable of displaying temperature in an analog format and digitally. The EGT which is based on probes that are located adjacent to the exhaust outlet for the TIT probe and each cylinder. In case it is installed, it is located next to a turbo charger. It is not a must for the probes to be collocated with the main probes; hence EDM 700 System may not be at a point of indicating the same as that of aircraft primary instruments.

1. Features of the EDM 700 System

The essential and optional features of the EDM 700 System are as follows;-

• Has a data retrieval software
