a. Remove the power cable (5) from the front of the test set, or
b. Remove the power cable from the wall socket. The wall socket connection
must remain accessible.
3.2 External Functional Earth/Ground Terminal
An external earth/ground connection stud (6) is available as a functional earth on the front
panel providing a connection/bonding point for other equipment to be connected to the
same earth/ground connection as the test set (This is not a protective earth/ground
connection).
3.3 Pneumatic Connections
No external pneumatic pressures or vacuums are required as the ADTS contains internal
pressure and vacuum pumps.
Hoses (available as orderable accessories on the datasheet) are used for connection to the
“Pitot” (Pt) (1) and “Static” (Ps) (2) output ports of the ADTS.
The “Pitot” (Pt) and “Static” (Ps) outputs can then be connected to the corresponding Pitot
and Static connectors on the aircraft or aeronautical instruments.
The maximum Pt and Ps output pressure is 2 bar absolute.
The following table details the possible connector specifications:
