7.2.4 Temperature sensor
1. Push New calibration. A calibration screen is displayed and the instrument measures two
temperature values and checks the stability of the measurements. Provided the measurements
are stable, you can choose to accept or reject the new values. Press Validation to store the new
setting.
7.2.5 Carbon dioxide sensor
A Verification option is also available for this sensor. The process is the same as a new calibration.
When verification is complete press the Ok button to exit. No report is produced for the verification
process. The CO sensor is calibrated using pure CO
2
air is provided by an internal pump that takes air directly from the atmosphere.
1. Push New calibration. A calibration screen is displayed showing the gas purity data of the main
gas. If the value is incorrect, enter the correct value in the Gas purity box.
2. When the measurement stabilizes press the Validation First Point button. A new measurement
is then initialized and the internal air pump automatically activated.
3. When the measurement stabilizes press the Validation Second Point button.
4. You now have the opportunity to accept the calibration, store the new values, and write the
details to the calibration report file. If the calibration cannot be performed, an error message will
be displayed giving the reason.
7.2.6 Flow sensor
1. Push New calibration. A calibration screen is displayed and the instrument will then compute the
measured flow in four steps (at 0.200 mL/s, 0.400 mL/s, 0.800 mL/s and at 0.000 mL/s). The
results are displayed on screen.
2. After a few minutes, when the process is complete, the Validation button is highlighted. Press
this button to accept the calibration (you will need to confirm acceptance).
7.2.7 Oxygen sensor
The O sensor is calibrated in-situ with an air pump providing a continuous flow of fresh air in front of
2
the sensor head.
1. Push New calibration. A calibration screen is displayed.
2. The value Ratio ideal membrane is a percentage of the current against the ideal current for the
membrane being used.
3. The value Variation shows the percentage of this measurement against the last sensor
calibration measurement.
4. The Calibration Status box at the bottom of the screen shows the current calibration process
with a bar graph below it to indicate the progress.
5. On completion, only if the calibration is valid will the Validation button be displayed. Press this
button to accept the calibration, store the new values, and write the details to the calibration
report file. If the calibration cannot be performed, an error message will be displayed giving the
reason.
7.3 Measurement process
7.3.1 Main screen
The initial screen displays standard information about the package to measure. You have the
possibility to change the user and the package type to be measured.
7.3.2 Start analysis
Note: Once a sample has completed the measurement process it will contain a small amount of antifoam.
Therefore, after measurement, ensure the sample is disposed of in a sink (or similar) to avoid any risk of ingestion.
