Preparing to Measure Mainstream CO2
Attach the transducer connector to the CO
Wait 20 minutes, allowing the transducer to reach its operating temperature and a stable thermal
Perform an accuracy check and then, if necessary, calibrate the transducer.
Checking Transducer Accuracy
Check transducer accuracy at least once a week or if you doubt the CO
Look at the calibration value displayed in the
as the value on the calstick? If not, calibrate the transducer now.
Place the transducer on the low cell of the calstick (labeled 0.0 mmHg or "ZERO"). The reading
on the screen should be zero within ±1 mmHg within one minute.
Place the transducer on the high cell of the calstick. The reading on the screen should be within
±1 mmHg of the value on the calstick within one minute.
If both readings are in range, you can leave calibration mode and begin monitoring. If either of the
readings is out of range, calibrate the transducer.
Calibrating the Transducer
Check that the windows on the calstick are clean and clear.
Place the transducer on one of the calstick cells and select
