6 INSTALLATION
The CO
2
sensor in the cGas Detector goes through a burn in period at our
factory prior to shipping so it is ready for operation upon arrival. If you install the
cGas Detector when it arrives, the sensor will not require a long warm up period
(about 2 minutes).
NOTE:
CETCI suggests that upon power-up, all sensors be left to warm up for
24 hours prior to considering the gas readings to be accurate.
If the device is not installed within two weeks of delivery, the sensor may
require a longer warm up time to stabilize (approximately 48 hours) and
provide accurate readings.
NOTE:
All sensors are calibrated in the factory before they are shipped
and should not require calibration at the time of a routine installation or
replacement.
NOTE:
Temperature affects calibration. It is important to ensure the gas is
at the appropriate temperature during calibration. If the sensor is being used
in an extreme temperature range, calibration should be done in that same
temperature range.
A bump test will help you determine if a sensor requires calibration. If the
sensor still does not respond as it should after a successful calibration, it
probably requires replacing.
