Teledyne 2010A - Split architecture thermal conductivity analyzer - Manual (Page 11)

Part I 1- Teledyne Analytical Instruments
Thermal Conductivity Analyzer Part I: Control Unit
• Microprocessor based electronics: 8-bit CMOS microprocessor
with 32 kB RAM and 128 kB ROM.
• Auto and remote calibration capabilities.
• Four analog outputs: two for measurement (0–1 V dc and Iso-
lated 4–20 mA dc) and two for range identification.
• Compact and versatile design: Small footprint, yet internal com-
ponents are accessible.
1.4 Model Designations
The Model 2010A is ordinarily custom programmed at the factory to
fit the customer’s application. Many parameters, including the number of
channels, the gas application, the materials specification of the sampling
system, and others, are options. The most common options, are covered in
this manual. See the Specific Model Information checklist in the front mat-
ter of this manual for those that apply to your Model 2010A analyzer. Some
standard models that are not covered in this manual are listed here.
Models 2000A: Both analysis section and control unit are in a single
general purpose enclosure.
Models 2020: Both the analysis section and control unit are in a single
explosion proof enclosure.
1.5 Operator Interface (Front Panel)
The standard 2010A is housed in a rugged metal case with all controls
and displays accessible from the front panel. See Figure 1-1. The front
panel has thirteen buttons for operating the analyzer, a digital meter, and an
alphanumeric display. They are described briefly here and in detail in the
Operations chapter of this manual.
Function Keys: Six touch-sensitive membrane switches are used to
change the specific function performed by the analyzer:
• Analyze Perform analysis for target-gas content of a sample
gas.
• System Perform system-related tasks (described in detail in
chapter 4, Operation.).
• Span Span calibrate the analyzer.
• Zero Zero calibrate the analyzer.
