During start-up the EDM may reset (typical on 14 vdc systems). This is normal due to extremely low battery voltage
due to starter amperage draw. 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.
