and EMS units, a “SNAPSHOT” log is also recorded and can be downloaded. The snapshot log records the value of all
parameters anytime an alert occurs.
INTERNAL LOGGING
To activate internal data logging, enter the EMS > SETUP > GLOBAL
> DATALOG CONFIG menu and set RECORDING to ON. Set the
INTERVAL depending on how frequently you wish data to be stored.
Data can be stored at intervals of 1, 3, 5, 10, 30, and 60 seconds.
Leaving the RECORD AT BOOT option set to NO causes the
RECORDING option to be reset to OFF every time power to the EMS-
D10 is cycled. Setting it to YES ensures that the EMS-D10 begins
logging data automatically at boot up. If you wish to mark the data log
at any point, select the MARK NOW function and press SEL►. This
inserts a notation in the data log retrieved by your PC, allowing you to
quickly find the place in your data when you marked the record. For
information about retrieving data and reading the file produced, please
see the help file included in the Dynon Product Support Program (version 3.0 and higher). Note that the internal data log
only includes data for the engine monitor portion of the EMS-D10. EFIS data is not logged.
The EMS-D10 has a limited amount non-volatile internal storage for the data log. With a 1-second recording interval, at
least 30 minutes of cumulative data can be recorded; with a 10-second interval, at least 5 hours; with a 30-second
interval, at least 15 hours, and with a 60-second interval, at least 30 hours. When the EMS-D10 internal storage fills up,
new records overwrite the oldest records. To delete the records in internal storage, select ERASE LOG, ERASE
MIN/MAX LOG, or ERASE SNAPSHOT LOG (only available on certain units).
