Sensor Calibration and Verification
For accurate readings, calibrate the Capnostat every time you connect it to a different
etCO
2
module or pod. Calibration is unnecessary if you disconnect the sensor and
later reconnect it to the same device. You can display the date and time of the last
Capnostat sensor calibration by clicking on
Sensor Cal.
in the etCO
2
menu. Verify
the sensor calibration periodically to check that it is functioning correctly, or when
you suspect changes or inaccurate readings.
To calibrate and verify the Capnostat sensor
1. Make sure the monitor is turned on and properly connected to the module or
pod.
2. The monitor displays a message informing you that the sensor is warming up
(~2 minutes at room temperature).
3. When the sensor reaches a stable temperature, the monitor instructs you to
place the sensor on the zero cell.
4. Locate the zero and reference cells on the sensor cable.
5. Place the sensor on the zero cell. The calibration process begins automatically
and takes about 20 seconds.
6. When calibration is complete, the monitor instructs you to place the sensor on
the reference cell.
7. Place the sensor on the Reference cell. The monitor displays the message
etCO2 Verifying Sensor Cal
.
8. When the verification is complete, the monitor displays the message etCO2
Sensor Cal. Verified. You can now use the sensor.
If verification fails, the monitor again displays the message e tCO2 Place Sensor on
Zero Cell . In this case, repeat the process from step 5. A status message appears if
calibration fails again (see table at the end of this chapter).
