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 of the rear panel.
If you conduct a sampling, please do the following:
ƒ 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.
ƒ Use a flow rate that is ≤ 0.5 liters/minute to take a sample.
ƒ Keep the door closed to minimize heat loss.
ƒ 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.
