out of calibration.
2. Take another sensor from the building
and replace the suspect sensor to see if
the readings are similar.
3. Connect the sensor outdoors (if
possible). The readings should be
between 350 and 450 ppm.
4. Connect the sensor to nitrogen gas from
a Model 2075 calibration kit. The
reading should be close to zero.
5. If the sensor still proves to be out of
calibration, calibrate the sensor
according to the instructions included in
your calibration kit, or call for a Return
