If the device will not be clinically operational with the O
2
regulation activated, but there
is N
2
gas available, the test should be conducted with O
2
regulation switched on and with
N
2
gas supply.
If the N
2
is not available, the test can be done without it.
Make sure that the Esco Medical data logger software is running.
Check that parameter are logged and give a meaningful reading. Let the device run with-
out interfering for at least 6 hours. Analyze the results on the graphs.
Pass I:
Internal sensor temperature variation from set point is within ± 0.1 °C absolute.
Pass II
Internal sensor CO
2
concentration variation from setpoint within ± 0.2% absolute.
Pass III:
Internal sensor N
2
concentration variation from setpoint within ± 0.2% absolute.
Pass IV:
Gas flow CO
2
less than 2 l/h (for Mini MIRI
®
Humidity model
–
less than 4 l/h).
Pass V:
Gas flow N
2
less than 8 l/h (for Mini MIRI
®
Humidity model
–
less than 12 l/h).
