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.
5 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
1 Check that the windows on the calstick are clean and clear.
2 Place the transducer on one of the calstick cells and select Start Cal 1.
3 Enter the calibration value printed on the calstick then press Confirm to start calibration.
4 When the message CO2 CAL 1 calibration done - start CAL 2 calibration
appears, put the transducer on the other cell and select Start Cal 2 then press
Confirm.
5 When you see the message CO2 calibration completed. Leave calibration
mode., calibration is complete.
6 Select Cal Mode to switch calibration mode off. You cannot monitor in calibration mode.
