This user interface is also available using a hand-held,
detachable keyboard display, the CR1000KD, as described in
Section 4.1.4, Other Accessories. The CR1000KD may be
preferred when multiple AP200s are to be maintained. The
factory-mounted keyboard display is permanently attached, so it
cannot be forgotten or misplaced. For more detail on the
keyboard display, see the CR1000 Measurement and Control
System Operator’s Manual.
The AP200 can be configured with one of several mounting options for the
system enclosure. The AP200 system enclosure is similar to the Campbell
Scientific ENC16/18 enclosure. The same mounting options are available and
outlined below:
• Triangular tower (UT10, UT20, or UT30)
• Tripod mast (1.5 in to 1.9 in diameter)
• Tripod leg (CM106 or CM106K tripod only)
• Large pole (4.0 in to 10.0 in diameter)
• No mounting bracket
Consult the ENC10/12, ENC12/14, ENC14/16, ENC16/18 Instruction Manual,
available at www.campbellsci.com , for details on mounting bracket options.

its equivalent is recommended. This tubing has a 0.25-in outer diameter to fit
the Swagelok ® fittings on the intake assemblies and the system enclosure. The
