2.3.3 O2 Sensor Calibration(Only for A3's and A5's without an
AG module)
NOTE: Both a 21% and 100% O2 calibration MUST BE performed before first
use of the A5/A3. The O2 sensor is not calibrated with the machine at
the factory.
NOTE: Calibrate the O2 sensor when a great deviation of O2 concentration
monitored value occurs or when the O2 sensor or ventilator control
board is replaced or when prompted by the anesthesia system.
NOTE: Before calibration, observe if the O2 sensor displays numerics on the
measure screen. If not, check the O2 sensor connection line, or replace
the O2 sensor until measure numerics are displayed.
2.3.3.1 21% O2 Calibration
Follow these steps to calibrate the O2 sensor at 21% O2:
1. Select Setup > System > Calibration >O2 Sensor or Setup > Service > Calibration > O2 Sensor to
access the screen as shown below. The General tab shows only 21% O2 Sensor calibration; the
System and Service tabs require passwords and show both 21% and 100% O2 Sensor
calibration. Set up the machine as per the instructions on the screen. Select Begin to start
calibration.
