1 Introduction Model 6600
Teledyne Analytical Instruments
1.3 Main Features of the Analyzer
The Model 6600 Photometric Analyzer is sophisticated yet simple to
use. The main features of the analyzer include:
• A 2-line alphanumeric display screen, driven by microprocessor
electronics, that continuously prompts and informs the operator.
• High resolution, accurate readings of concentration from low
ppm levels through to 100%. Large, bright, meter readout.
• 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
0-100 %) allow best match to users process and equipment.
• Calibration range for convenient zeroing or spanning.
• 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.
• RS-232 serial digital port for use with a computer or other digital
communication device.
• Analog outputs for concentration and range identification.
(0-1 V dc standard, and isolated 4–20 mA dc)
• Superior accuracy.
• Internal calibration-Manual or Automatic (optional).
1.4 Operator Interface
All controls and displays on the standard 6600 are accessible from
outside the housing. The instrument has two simple operator controls. The
operator has constant feedback from the instrument through an alphanumeric
display, and a digital LED meter. The displays and controls are described
briefly here and in greater detail in chapter 3. See Figure 1-1.
