1. HOW TO OPERATE 1 Firmly mount the Sampling T in the taper on top of the case 2 Switch the instrument ON using the switch located on the end nearest the display The LCD at the top of the monitor will read a high number which will rapidly fall ios Anew mini mouthpiece should be fitted to the Sampling T for each new user 4 The unit should be allowed to warm up until the display shows 000 If this is not achieved within two or three minutes please refer to the Display re zeroing section 5 The subject should take in a deep breath hold it for 10 seconds and then breath out slowly through the mouthpiece over a period of 20 seconds or more O Record the highest reading indicated on the display after completing the blow NOTE ENVIRONMENTAL MONITORING Environmental carbon monoxide levels may be monitored by removing the Sampling T switching the unit ON and recording the highest display level DISPLAY RE ZEROING Changes in the ambient operating temperature or CO level can cause small drifts in the instrument zero If adjustment is necessary slowly move the small slider control adjacent to the liquid crystal display window until the display shows all zeros Ifthe instrument will not zero possible causes are high ambient levels of CO faulty calibration or equipment malfunction To eliminate the possibility of the high ambient level the unit should be removed to another location and zeroing attem2.

3. pted again CALIBRATION The Vitalograph BreathCO is re calibrated by exposing it to a gas of known concentration BreathCO Calibration Kit Cat No 29 504 This is usually 50 ppm CO CALIBRATE ONLY IN A WELL VENTILATED ENVIRONMENT 1 Turn BreathCO on allow display to stablize then adjust to 0 if needed 2 Connect the gas to the Sampling T 3 Let the gas flow slowly approx 0 5 ltr min through the Sampling T into the instrument When using the Vitalograph Calibration Kit the regulator should be set to 5 psi 4 Once the displayed value stops increasing it should be within 5 of the gas concentration 1 e 48 52 5 If the instrument does not display a reading within the specifications slowly adjust the SPAN recessed adjustment screw on the rear of the instrument until the display reads 50 Be careful or you could damage it If this cannot be achieved the electrochemical sensor in the product must be replaced Please contact our technical support department if this should occur 6 After calibration disconnect the Sampling T and allow the instrument to settle for 5 minutes Recheck the instrument zero Re adjust the zero if necessary as detailed in the previous section GENERAL MAINTENANCE A General maintenance and calibration should be performed on an annual basis A calibration check should be performed as required The Sampling T should be changed after approximately 50 tests have been performed When
4. replacing the battery be sure to use only alkaline batteries 1 Press down on panel marked OPEN and slide cover in direction of arrow Then gently lift cover from the instrument 2 Remove and discard the old battery 3 Replace with a new battery of the correct type 4 Ensure that the connector is fitted correctly 5 Ensure the leads are tucked nearly away before replacing battery compartment cover
