On 14 vdc systems during start-up the EDM may reset it self. This is normal due to extremely low battery voltage.
The conditions and test required for TSO approval of this article are minimum performance standards. It is the
responsibility of those desiring to install this article either on or within a specific type or class of aircraft to determine
that the aircraft installation conditions are within the TSO standards.
The article may be installed only if installation of
the article is approved by the Administrator. The functions of Volts, Amps, and Horse Power were tested to DO-160D
and DO-178B, but not TSO’d since no TSO exist for these functions. Deviation granted for TSO-C49b to include digital
display and sensor. All TSO required probes, transmitters and sensors also tested to DO-160D.
