Introduction

BDS 3960

 

 

 

 

 

 

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.

1.4Front 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.
