Figure 11 shows a typical gas response from a Standard Calibration. The zero gas is first run
for 60 seconds, then the span gas is run for 60 seconds. When run regularly, these responses
are enough to calibrate and ensure precision of the gas concentration sensors.

Recoveries are used to verify that the whole system is working properly. It also serves as
a calibration of the air flow meter.
The process involves releasing a measured amount of CO
2
into the system, then comparing
that known amount to GreenFeed’s calculated value.
