2. If required, you can take a sample of the gas inside the chamber using the CO
2
sample port, and check it using a CO
2
gas analyzer. The CO
2
sample port is
located at the top front of the case, inside the outer door.
If you conduct a sampling, please ensure the following:
Turn off the CO
2
gas by re-programming the setpoint for CO
2
to 0.0% to
prevent CO
2
from being injected into the chamber and giving a false
reading.
A flow rate
≤
0.5 liters/minute is used to take a sample.
The door is kept closed to minimize heat loss.
Remember to reset the CO
2
setpoint to the desired level after sampling.
We recommend that you perform a CO
2
AutoZero prior to sampling ( see Section
3.5 ).
3. We also recommend that you AutoZero the CO
2
system at least once every 28
days to ensure that CO
2
level is correct.
