Introduction BDS 3000
Teledyne Analytical Instruments 2
• Versatile analysis over a wide range of applications.
• Microprocessor based electronics: 8-bit CMOS
microprocessor with 32 kB RAM and 128 kB ROM.
• Three user definable output ranges (from 0-100 ppb through
0-100 ppm) allow best match to users process and
equipment, plus a fixed 100 ppm over range.
• Auto Ranging allows analyzer to automatically select the
proper preset range for a given measurement. Manual
override allows the user to lock onto a specific range of
interest.
• Two adjustable concentration alarms and a system failure
alarm.
• Extensive self-diagnostic testing, at startup and on demand,
with continuous power-supply monitoring.
• Two way RFI protection.
• RS-232 serial digital port for use with a computer or other
digital communication device.
• Four analog outputs: two for measurement (0–1 VDC and
Isolated 4–20 mA DC) and two for range identification.
• Convenient and versatile, steel, flush-panel or rack-
mountable case with slide-out electronics drawer.
1.4 Front Panel (Operator Interface)
The standard BDS 3000 is housed in a rugged metal case with all
controls and displays accessible from the front panel. See Figure 1-1.
The front panel has thirteen buttons for operating the analyzer, a digital
meter, an alphanumeric display, and a window for viewing the sample
flowmeter.
Function Keys: Six touch-sensitive membrane switches are used to
change the specific function performed by the analyzer:
