The CDM-6000 is factory calibrated for operation at sea level. When operated
at higher elevations, the calibration may be adjusted to correct for this factor.
The CDDS-2 can be set to the exact operating elevation to eliminate the
measurement error caused by decreased barometric pressure at higher
altitudes. This altitude compensation is done by the CDDS-2 controller. Let
the CDM-6000 stabilize to the ambient CO2 concentration. To change the
operating elevation:
1. Press and hold both the 'SET' and 'SENSOR' buttons for about five (5)
seconds until all the yellow LED's blink. The current elevation setting is
displayed.
2. Use the 'UP' and 'DOWN' buttons to adjust the display reading to the
current elevation in feet. The display moves in 10 foot increments.
3. After several seconds of no button activity the CDDS-2 reverts to its normal
operating mode.
