Section 8 - Memory and Data Download
The EDM compresses and records all displayed parameters once every
six seconds (default) in Long Term Data Memory (note: you can change
this rate to be 2 to 500 seconds). This data is retrievable by inserting a
USB Drive into the jack on the front of the instrument and following the
prompts. You can choose to retrieve ‘ALL’ the data stored in the EDM,
or only the ‘NEW’ data recorded since your last retrieval. In either case,
the selected data in the EDM is not erased. The data can later be viewed
on EZTrends, a PC program available from JPI or over the internet.
Recording typically begins when EGTs are greater than 500°F or RPM is
greater than 500. The amount of data that the EDM can store will vary
depending on how rapidly parameters change. The typical storage
capacity is greater than 100 hours at a 6 second recording interval, but
can vary depending on configuration. When the memory becomes full,
the oldest data will be discarded to make room for the newest. All data
are time-stamped. The EDM contains a real-time clock that may be set
when you initially program your instrument. You may change the
recording interval from 2 to 500 seconds, even in flight (when you
change the interval in flight, the current flight file is closed and a new
flight file is started at the new interval).
