6.13.5. Electric Test

The electric test function substitutes simulated signals for CO2 MEAS and CO2 REF, generated by circuitry on the sync/demod board, for the output of the IR photo-detector. While in this mode the user can also view the same test functions viewable from the main SAMPLE display. When the test is running, the concentration reported on the front panel display should be 40.0 ppm.
