6.8.5 Zero
The purpose of zero calibration is to eliminate the influence of baseline drift on results to guarantee the accuracy
of the measured results in the process of measuring.
Side-stream
The side-stream CO
2
module automatically calibrates zero when necessary. Users can also manually
zero-calibrates as desired: [User Maintain>>]-[CO
2
Maintenance>>]-[Zero]. Zero calibration requires
disconnecting the animal airway.
Attention
Don
’t perform zero calibration when the temperature is not stable.
Main-stream
The main-stream CO
2
module need zero calibration in the following cases:
The airway adapter is exchanged.
The sensors is re-connected with the module.
The gas readings are found having errors.
The system prompts ‗CO
2
Need Zero‘.
In this case, please check the airway adapter and make sure its adapter window is not blocked by mucus, etc.
Cleaning or adapter replacement is needed when a blockage is found.
The zero calibration steps are as follows:
1.
Connect the sensor with the CO
2
module.
2.
Select CO
2
parameter region and choose [CO
2
Setup]-[Operate Mode], and set [Measure].
3.
When warming-up is done, mount the sensor on a clean and dry airway adapter. The adapter should be
open to the air and all CO
2
sources should be isolated, including breathing machine, animal‘s respiration
and operator‘s respiration.
4.
Select [CO
2
Maintenance>>] in the menu [User Maintain>>]-[Zero], and ‗CO
2
Zero Progress‘ is
prompted on the screen.
5.
The prompting message disappears when the zero calibration is completed.
Attention
The module must be zero-calibrated when the system prompts that CO
2
measure is over the time
allowed. The module should be zero-calibrated regularly after a long use period.
Zero calibration must be performed by specialized technicians.
