Microstream Sensor Calibration and Calibration Check
Perform the Calibration Check as described on page 26.
Calibrate your Microstream sensor when directed by CO2 Calibration Overdue Technical Alarm. This
alarm is displayed when one of these two events happen (as reported on the Service – EtCO2 screen):
• 4000 operating hours passed since the last calibration
• a calendar year passed since the last calibration.
TIP: Examine these values and calibrate the sensor if any of them is close to the limit to prevent the CO2
Calibration Overdue Technical Alarm.
 To calibrate the Microstream sensor:
1 Set up the equipment as shown in Figure 20 on page 27.
2 Enter the Service Mode and select EtCO2 to access the EtCO
2
maintenance menu.
3 Select Calibrate.
4 Follow the on-screen instructions.
Disposal of Empty Calibration Gas Cylinders
 To dispose of empty calibration gas cylinders:
1 Empty the cylinder completely by opening the valve.
2 When the cylinder is empty, either remove the valve stem from the fill (or regulator) hole, or drill a
hole in the cylinder.
3 Write “Empty” on the cylinder and dispose of it appropriately for scrap metal.
WARNING: Ensure that the cylinder is completely empty before trying to remove the valve stem or drill the tank.
