FAQ

What is the purpose of the Electric Test?

The Electric Test activates a diagnostic circuit to simulate the output of the IR detector, providing a constant, stable CO reading of about 40 ppm.

How does the D/A output test work?

The D/A output test cycles 3 analog output channels from 0% to 100% of Full Scale in 20% FS steps, exercising electronic sub-systems of the Analyzer.

What are the I/O signals for the Teledyne API Model 300 CO Analyzer?

The I/O signals include bench, wheel, and box temperatures, DC power supply composite voltage, and various output readings in mV.
