'Automatic' calibration means that the instrument will calibrate zero in the display until ambient carbon monoxide levels reach approximately 80 ppm's. Should ambient CO levels exceed this level, a 'CO sensor error' will be displayed.
'Manual' calibration means that the instrument will calibrate to whatever levels of CO are detected in the ambient air.

The Fyrite Pro series of instruments is primarily designed for basic residential testing.
The Fyrite Pro does not have a memory feature to save test results. Saving test results allows the user to take multiple tests (light off, run and shut down, for example) and print off the test results once testing is complete.
The Fyrite Pro's sample pump is not as strong as the PCA's pump. This limits the length of the hose and probe assembly which can be used. The PCA can pull a sample through a 20' hose and probe assembly accessory.
The Fyrite Pro's display only shows 2 parameters at once while the PCA's display shows all test results simultaneously.
The Fyrite Pro can be set up by the end user to do either a manual or automatic calibration during the 60 second warm up period, the PCA does an automatic calibration (see #1).
