Trace Oxygen Analyzer Operation
Teledyne Analytical Instruments 27
Operation

4.1 Introduction

Once the analyzer has been installed, it can be configured for your
application. To do this you will:
Set system parameters.
Establish a security password, if desired, requiring the
operator to log in.
Establish and start an automatic calibration cycle, if desired.
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 3000ZA, these default values are in
effect:
Ranges: R1 = 100 ppm, R2 = 1.00 %, R3 = 100 %
(although sensor maxes out around 95% O2).
Auto Ranging: ON
Alarm Relays: Active, 80.00 and 90.00 ppm, HI, Not failsafe,
Not latching.
Zero: Auto, every 7 days at 12 hours, disabled.
Span: Auto, every 7 days at 12 hours, disabled.
Span values: High sensor = 85%, Medium sensor = 2 %, and
Low sensor= 80 ppm. Span Timer 7 min.
Password: TAI
If you choose not to use password protection, the default password
is automatically displayed on the password screen when you start up and
you have access to all functions of the analyzer.
