Teledyne API Model 200AU NOX Analyzer Instruction Manual, 02293, Rev. F

NOTE

On vacuum vs absolute pressure:

Many vacuum gauges read relative to ambient pressure, therefore a reading of 25" of mercury (Hg) at sea level (which would give an absolute pressure of about 5" Hg in the reaction cell) would read only 20" Hg at high altitude sites. Therefore in this manual the vacuum specification of 5" Hg pressure is given as an absolute pressure

-5"Hg-A - reference against zero absolute pressure (a perfect vacuum) thus removing ambiguities for high altitude sites.

4.2.3Computer Hardware and Software

CPU Board

The M200AU Analyzer is operated by an V40 series micro computer. The computer's multitasking operating system allows it to do instrument control, monitor test points, provide analog output and provide a user interface via the display, keyboard and RS-232 port. These operations appear to be happening simultaneously but are actually done sequentially based on a priority queuing system maintained by the operating system. The jobs are queued for execution only when needed, therefore the system is very efficient with computer resources.

The M200AU is a true computer based instrument. The microprocessor does most of the instrument control functions such as temperature control, valve switching. Data collection and processing are done entirely in the CPU with the final concentration values being sent to a D/A converter to produce the instrument analog output.

The computer memory is divided into 3 sections: ROM memory contains the multi-tasking operating system code plus the instructions that run the instrument. The RAM memory is used to hold temporary variables, current concentration data and data acquisition system data. The EEPROM memory contains the instrument set-up variables such as range and instrument ID number. The EEPROM data is non-volatile so the instrument can lose power and the current set- up information is preserved.

4.2.4 V/F Board

The V/F board is multifunctional, consisting of A/D input channels, digital I/O channels, and analog output channels. Communication with the computer is via a STD bus interface. The computer receives all of the instrument data and provides all control functions through the V/F board.
