unit is used for this. Use sample port-6 for validation. It is essential to have a high-precision
gas analyzer for CO

and O

available to do the test.
Please follow these simple rules while testing gas concentration:
•
Check the CO
2
gas setpoint.
•
Check the actual CO
2
gas concentration to ensure the setpoint is reached and gas con-
centration is stabilized around the setpoint.
•
Remember not to open any lids for at least 10 min, before starting the test or during
the testing itself.
Please refer to the "13.5.4 CO
2
calibration menu" section for more information on how to
perform the CO
2
gas calibration.
PASS: CO
2
concentration measured must not deviate more than ± 0.2% from the
setpoint.
36.3 O
2
gas concentration check
The O
2
gas concentration is checked for deviations. The gas sample port on the side of the
unit is used for this. Use sample port-6 for validation. It is essential to have a high-precision
gas analyzer for CO
2
and O
2
available to do the test.
Please follow these simple rules while testing gas concentration:
•
Check the O
2
gas setpoint.
•
Check the actual O
2
gas concentration to ensure the setpoint is reached and gas con-
centration is stabilized around the setpoint.
•
Remember not to open any lids for at least 10 min, before starting the test or during
the testing itself.
Please refer to the "13.5.5 O

calibration menu" section for more information on how to
perform the CO

gas calibration.
PASS: O

concentration measured must not deviate more than ± 0.2% from the
setpoint.
Gas analyzers use a small pump to draw outgas from the location being sampled.
The pump capacity varies from brand to brand. The gas analyzer's ability to return the
gas sample to the incubator (loop sampling) avoids negative pressure and ensures
accuracy. The performance of the MIRI
®
II-12 multiroom IVF incubator will not be
affected, as the gas in the compartment is not under pressure, and the reading is just
an artifact based on unsuitable measuring equipment. Contact Esco Medical or the
