Calibration
6.8 Flow sensor
After selecting this option, the details of the last flow sensor calibration are displayed. This
shows the values recorded, and information about who performed the last calibration and when.
The due date of the next calibration is also shown (determined by the parameters entered in
Scheduled operations on page 43
).
Important Note:
This procedure uses information from the pressure sensor. Be sure that this
parameter is reliable (i.e. a recent pressure sensor calibration has been performed - see
).
6.9 Oxygen sensor
After selecting this option, the details of the last oxygen sensor calibration are displayed. This
shows the values recorded, and information about who performed the last calibration and when.
The due date of the next calibration is also shown (determined by the parameters entered in
Scheduled operations on page 43
).
Important Note:
This procedure uses information from the barometric pressure sensor. Be sure
that this parameter is reliable (i.e. a recent barometric pressure sensor calibration has been
performed - see
Barometric pressure sensor on page 46
).
The O
2
sensor should be calibrated after each sensor service or when the calibration due date
parameter has been passed. After a sensor service, wait at least 30 minutes after mounting a
new membrane before calibrating.
Note:
For full details on sensor servicing, please refer to the
A1100 Sensor Installation and Maintenance
Manual
that was delivered with the instrument.
The O
2
sensor is calibrated in-situ with an air pump providing a continuous flow of fresh air in
front of the sensor head.
Flow sensor
New calibration 1.
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).
3.
On completion a calibration report is created.
Verification
1.
The process is exactly the same as for a new calibration, but once the details
have been displayed on screen press the
Cancel
button to complete the process.
No report is produced.

Oxygen sensor
New calibration 1.
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.
Verification
1.
The process is similar to a new calibration, but once verification is complete press
the
Exit
button to complete the process. No report is produced.
