PROGRAMMING
As previously mentioned, the C16 is ready to operate when received. However, there are
a number of operating variable such as range, alarm setpoints, display damping, and sample
mode timing that can be programmed. In addition, sensor module zero adjustment and
calibration can be done from the programming menu.
To access the programming menu, turn on the detector and wait until the main display
appears (Display D10 - see page 16). Note that one of the keys has no designation above it on
the function line of the display. Press and hold the unmarked key and then press and hold the
key marked MENU. Hold both keys down for approximately 5 seconds. The display will go
blank, at which time you should release both keys. The display should now appear like the
display in PD1 below. Press the MORE key to toggle between display PD1 and PD2.

Second display for access to programming display variables
or adjusting “Sample Mode” timing functions.
These displays are your starting point for specific programming functions. Pressing the
SENS key from PD1 provides access to sensor zeroing and spanning functions. Pressing the
ALRMS key from PD1 provides access to the routines for adjusting alarm setpoints. Pressing the
DISP key from PD2 allows adjustment of display variables. Pressing the SMPL key from PD2
allows adjustment of the timing variables used in the “Sample Mode” of measurement outlined on
page 24 of this manual.
Sensor modules shipped with the C16 have been factory calibrated. No adjustments
should be made to the calibration settings unless you have the necessary gas standards to
perform such adjustments. Sensor adjustments are described in the last section of this
programming section.
