Teledyne 3000ZA-3X - Trace oxygen analyzer - Manual (Page 14)

Introduction 3000ZA-3X
Teledyne Analytical Instruments 2
 Three Zirconium oxide sensors to provide higher range
of analysis flexibility. The analyzer can cover ranges as
low as 0-10 ppm or as high as 0-95%.
 No reference gas required
 Versatile analysis over a wide range of applications.
 Microprocessor based electronics: 8-bit CMOS
microprocessor with 32 kB RAM and 128 kB ROM.
 Three user definable output ranges (from 0-1 ppm
through 0-95%) allow best match to users process and
equipment.
 Auto ranging allows analyzer to automatically select the
proper preset range for a given measurement. Manual
override allows the user to lock onto a specific range of
interest.
 Two adjustable concentration alarms and a system
failure alarm.
 Extensive self-diagnostic testing, at startup and on
demand, with continuous power-supply monitoring.
 CE compliance
 RS-232 serial digital port for use with a computer or
other digital communication device.
 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.
1.4 Model Designations
3000ZA:
Standard model for sample under pressure
3000ZA-C: In addition to all the standard features, this
model also has separate ports for zero and
span gases, and built-in control valves. The
internal valves are entirely under the control
of the 3000ZA electronics to automatically
