Calibration
Calibration should only be performed by personnel with the necessary skills. Abuse of the
calibration controls may render the instrument inaccurate and unusable.
For calibrating the oxygen and carbon dioxide sensors, the supplied calibration adaptors and
tubing should be used as shown in the drawing below. Remove the adaptors from the sensors
after calibration. The drawing also shows a calibration gas bottle and flow regulator. These can be
purchased from Analox if necessary. Alternatively the user may opt to use their own calibration
gas, perhaps with a conventional pressure regulator and an in-line sample flow meter. Take care
not to over-pressurise the sensors, or they may be damaged.
The drawing below shows a calibration gas bottle with a flow regulator fitted providing sample gas
flow within the recommended range of between 0.3 and 1.0 litres per minute. The flow adaptors
simply push in to the oxygen and CO2 sensor inlet ports.
After calibration, the flow adaptors MUST be removed from the sensor inlets.
Note that a REM3 controller with only one gas sensor is supplied with a calibration kit with only
one flow adaptor. The two- flow adaptor kit will still work with only one sensor, but always make
sure that the flow adaptor first in line from the regulator is pushed into the sensor being
calibrated.
