7.3.9 AG Calibration (factory)
7.3.9.1 Preparations
Prepare the following before doing the calibration:
Gas cylinder, with a certain standard gas or mixture gas. Gas concentration should meet
the following requirements: AA
≥
1.5%, CO2
≥
1.5%, N2O
≥
40%, O2
≥
40%, of which AA
represents an anesthetic agent. a/c
≤
0.01 (a is the gas absolute concentration accuracy; c
is the gas concentration).
T-shape connector
Tubing
7.3.9.2 Calibration Procedures
Follow this procedure to perform a calibration:
1. Make sure that the system is not Standby and the AG module is in [
Measure
] state.
2. Wait for the AG module to be fully warmed up.
3. Select
the
[

] shortcut key

].
4. Check the airway and make sure that there are no occlusions or leaks.
Vent the sampling tubing to the air and check whether the current rate and set rate
are approximately the same. If the deviation is great, it indicates that there is an
occlusion in the tubing. Check the tubing for an occlusion.
Block the gas inlet of the sampling tubing. The current rate should drop rapidly and
the message of airway occlusion is prompted. Otherwise, it means that the airway
leaks. Check the airway for leakage.
Connect the test system as follows.
6. Open the relief valve and vent a certain standard gas or gas mixture and make sure that
there is an excess gas flow through the T-shape connector to air.
7. In
the
[
AG Module Cal.
] menu, the measured gas concentration and flow are displayed.
If the difference between the measured gas concentration and the actual one is
tolerable, a calibration is not needed.
If the difference is great, a calibration should be performed.
8. Enter the vented gas concentration. If you use only one gas for calibration, set other
gases’ concentration to 0.
9. Select
[
Calibrate
] to start a calibration.
