Oxygen Analyzer Introduction

Introduction
The Teledyne Analytical Instruments AD300 Oxygen Analyzer
here after referred to as AD300 and MD300 Oxygen Monitors with
alarms here after referred to as MD300 are portable instruments that
provide fast and accurate oxygen monitoring. In addition, the model
MD300 incorporates an audio/visual alarm capability. These instruments
are designed to monitor up to 100% oxygen concentration in breathable
gas mixtures. Because they are microprocessor-based, the AD/MD300
series have a unique combination of features that make them very easy
to use. The operator interface is accomplished through a series of
buttons located conveniently on the front face of the instrument. The
MD300 front face interface is shown in Figure 1-1. The AD300 is
similar but without the battery and alarm test buttons is shown in Figure
1-2.

Introduction AD300/MD300
Teledyne Analytical Instruments 10
Figure 1-2: AD300 Front View
The LCD display consists of up to 3.5 characters plus a decimal
point indicator capable of displaying up to 105%. (See Section 1.2
Options for alternate display configuration). An integral battery life
indicator is displayed continuously on the AD300 and ―on demand‖
with the MD300.
The instrument is powered by three AA alkaline batteries and is
designed to operate for 2000 hours in Non-alarm State.
Oxygen analysis is linear across the single range of 0-100% using
Teledyne’s class R17S oxygen sensor. A unique sensor failure alarm is
incorporated which warns the user if the sensor signal is lost or low.
When this occurs, the √ SENSOR display flashes. The alarm buzzer can
be silenced by pressing the ALARM SILENCE key. If the alarm
condition is not corrected within 115 seconds the alarm buzzer will
reactivate.
The MD300 unit incorporates a dual concentration alarm with
individual user-defined set points. The set points are displayed on the
lower portion of the LCD display with the low alarm set point appearing
at the lower left and the high alarm appearing on the lower right of the
display. The alarm circuitry provides both an audible and visual alarm.
