AG and O2 Concentration Monitoring Calibrate the AG Module
8.11 Calibrate the AG Module
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%, CO
2
≥1.5%, N
2
O≥40%, O
2
≥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
Follow this procedure to perform a calibration:
1. Connect the test system as follows.
2. Ensure that the system is in Standby mode. If not, select the End Case button in the Manual
tab and follow the on-screen prompts to end the case and enter Standby mode.
3. Select the Setup softkey > System tab (system password needed).
4. Select the Calibration button.
5. Select the Internal AG Module or External AG Module button.
6. Wait for the AG module to be completely warmed up.
7. Enter the actual concentration of the calibration gas.
8. Turn on the calibration gas canister. The system displays the real-time concentration of
calibration gas.
9. Select the Calibrate button to start to calibrate the AG Module. The system displays the
results of the calibration status when the process is completed.
10. After calibration, select the Done botton to close the Calibration window.
11. Select the Accept button to confirm the change, or select the Cancel button to discard the
change.
