ml/min.
"
7.
Ambient pressure
Check that the shown Ambient value corresponds with the current ambient pressure (±20
mmHg).
"
8.
Zero valve check
Feed calibration gas and check that the gas readings in the service menu correspond
with the values on the gas bottle sticker. Keep feeding gas, then activate the zero valve
from the menu. The CO
2
reading should drop back to near 0%.

sampling line and start following the Amb-Work value in the service menu. When the
value exceeds 130 mmHg, connect the other port of the flow cassette to the sample gas
out connector and switch off the pump.
Wait until the pressure inside the sampling system is stabilized, then observe the shown
Amb-Work value. The value, i.e. the pressure inside the sampling system should not drop
more than 6 mmHg in 20 seconds.
If the pressure drops more, first check the connections and repeat the test.
"
11. Check the flow rates
Wait until the Sample Flow value returns close to 150 ml/min.
