4 Appendix A - Equipping an Instrument

AML-1 RT is part of AML's X2change instrumentation ecosystem. Any sensor within this
ecosystem is compatible with any instrument. Sensors are identified by orange collars, and
instruments are identified by black decals on the instrument body and orange colouring within
the sensor ports. Only 'orange' sensors may be installed on 'orange' instruments. The previous
generation of blue-collar Xchange sensors are not compatible.
The process below describes the typical method for installing and removing sensors from an
instrument.

4.1 Installing sensors

1. Before installing X2Change™ sensors, ensure that the sensor port is clean and dry. Also
confirm that the port is 'orange' compatible by visually confirming the precedence of
orange coloring at the bottom of the port.
2. Check the X2Change™ sensor's o-rings for cleanliness and replace if damaged. Apply
o-ring grease to the new o-ring before replacing it.
3. Align the sensor with the sensor port so that the key of the mating connector pins are
aligned. Key alignment is important - it can be difficult to insert a sensor if the clocking is
not correct.
4. Place the sensor into the port and press the sensor in to compress the o-rings. Confirm
correct alignment of the key by pressing the sensor body into the port and twisting the
sensor. It will be possible to feel the key engage.
5. Push the sensor until it drops down into the port enough to allow the orange locking
sleeve threads to engage the port threads.
6. Hand-tighten the orange locking sleeve until it stops. The bottom of the sleeve should be
within 1 mm of the instrument end cap. Note: the collar is NOT intended to sit flush on
the instrument endcap. Never use tools to tighten the locking collar.
