Block Diagram of the Model 3000P Electronics | Teledyne 3000PA

Percent Oxygen Analyzer		Operational Theory 2

The signal processing electronics including the microprocessor, analog to digital, and digital to analog converters are located on the motherboard at the bottom of the case. The preamplifier board is mounted on top of the motherboard as shown in the figure. These boards are accessible after re- moving the back panel. Figure 2-7 is a block diagram of the Analyzer electronics.
