Operation

4.1Introduction

Once the analyzer has been installed, it can be configured for your application. To do this you will:

•Set system parameters:

•Calibrate the instrument.

•Define the three user-selectable analysis ranges, then choose autoranging or select a fixed range of analysis, as required.

•Set alarm setpoints, and modes of alarm operation (latching, failsafe, etc).

Before you configure your BDS 3960, these default values are in effect:

Ranges: LO = 100ppb , MED = 1000 ppb, HI = 10 ppm, Over-Range = 100 ppm

Auto Ranging: ON

Alarm Relays: Defeated, Alarm 1 at 1000 ppb, Alarm 2 at 100 ppb HI, Not failsafe, Not latching.
