Introduction BDS 3960

Teledyne Analytical Instruments 14

• 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 on to a specific range of

interest.

• Two adjustable concentration alarms and a system failure

alarm.

• Two way RFI protection.

• 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 3960 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 the pocket PC, a digital meter, an alphanumeric

display, and a window for viewing the sample flowmeter.

There are no keys to press on the front panel. All interface with

the analyzer is done through the touchscreen of the pocket PC. The main

functions on the touchscreen are listed below.

•System Perform system-related tasks

(described in detail in chapter 4,

Operation.).

•Span Span calibrate the analyzer.

•Zero Zero calibrate the analyzer.

•Alarms Set the alarm setpoints and

attributes for Alarm 1 and Alarm 2.

•Range Set up the 3 user definable ranges

for the instrument.

• Quit Quit analyzer application.
