NOTE: If the Gas Module cannot zero, sample, or calibrate, a message “Zeroing 
Error”, “Sampling Error” or “Calibrating Error” displays and the 
previous calibration data is restored. Repeat the calibration procedure 
from step 3. If problems persist, contact Mindray for technical support.
5. Attach the calibration gas canister to the regulator and turn it on. Increasing gas values appear 
in the window when the Gas Module samples the calibration gas. When calibration is complete, 
the message “Choose Accept” displays and the message “Complete” displays beside each 
measured value.
6. Select the Ab
ort or Accept button.
•The Accept button accepts the calibration values. 
After a successful calibration, the message “Disconnect Calibration Gas” displays, followed 
by the message “Calibration Successful”.   
Following an unsuccessful calibration, the message “Di
sconnect Calibration Gas” displays, 
and the message “Calibration Error” displays beside each measured value.
•The Abort button cancels the calibration and restores the previous calibration values.
