Oxygen Analyzer	Introduction

Figure 1-1: BDS-3960 Front Panel

Digital Meter Display: The meter display is a Light Emitting Diode (LED) device that produces large, bright, 7-segment numbers that are legible in any lighting. It produces a continuous readout from 0-999.9 ppb and then switches to a continuous ppm readout from 0-100.00 ppm. It is accurate across all analysis ranges without the discontinuity inherent in analog range switching.

Flowmeter: Monitors the flow of gas past the sensor. Readout is 0.1 to 2.0 standard liters per minute (SLPM) of nitrogen

CAUTION: THE POWER CABLE MUST BE UNPLUGGED TO FULLY DISCONNECT POWER FROM THE INSTRUMENT. WHEN CHASSIS IS EXPOSED OR WHEN ACCESS DOOR IS OPEN AND POWER CABLE IS CONNECTED, USE EXTRA CARE TO AVOID CONTACT WITH LIVE ELECTRICAL CIRCUITS.
