Instrument Cradle
The instrument cradle is a recessed area on the top of the SM-2009 that
is designed to accept the GX-2009. Insert the GX-2009 in the instrument
cradle when you perform a bump test or calibration. The cradle has
charging contacts on the bottom that mate with the contacts on the back
of the GX-2009. There are sample ports in the front of the cradle that
match up with the GX-2009’s sensors and route air and calibration gas to
the sensors during a bump test or calibration. An infrared (IR) port at the
back of the cradle lines up with the GX-2009’s IR port when it is inserted
in the cradle and is used to communicate with the GX-2009. A retaining
tab that holds the GX-2009 in the cradle is located to the right of the IR
port.
