6000A Analysis Unit, is versatile microprocessor-based instrument. Part I, of this manual covers the Model 6000A General Purpose Panel Mount Control Unit. (The Analysis Unit is covered in Part II of this manual.) The Control Unit is for indoor use in a nonhazardous environment only.
Internal calibration (optional). Control Unit Inner Control Panel The standard 6000A Control Unit is housed in a rugged panelmetal case with all remote controls and displays accessible from the front control panel. See Figure 1-1. The front control panel has a digital meter, an alpha- numeric Vacuum Fluroscent Display (VFD), and buttons for operating the analyzer.

Digital Meter Display: The meter display is a Light Emitting Diode LED device that produces large, bright, 7-segment numbers that are legible in any lighting. It is accurate across all analysis ranges. The 6000A models produce continuous readout from 0-10,000 ppm and then switch to continuous percent readout from 1-100 %.

Operational Theory 1 Operational Theory Introduction The Teledyne Photometric Analyzer uses the ultraviolet (UV) absorp- tion principle to detect and continuously measure a component of interest in a sample stream. The analyzer consists of a single sample cell, chopped beam, dual-wavelength UV process photometer and associated microprocessor based control unit and electronics.
1 Operational Theory Model 6000A Optical Bench Depending on the application, the analyzer comes with one of the following types of lamps: Deuterium (D), Quartz Iodine (L), or Mercury (Hg). Energy from the lamp, used as a source, is focused through a sample cell onto a photo detector.

1 Operational Theory Model 6000A The procedure to set up the optical bench, the signal processing front- end amplifiers, the standardization of outputs, and alarm systems are described in separate sections of the manual. Automatic Zero System To compensate for zero drift, which may occur during sampling, the analyzer zero reading is updated by the Auto-Cal function of the controller.
System Description The photometric analyzer is generally constructed for general-purpose (Model 6000A) use and is mounted on a BACKPLATE, an open rack, or in a closed cubicle. Photometer The three photometer modules are mounted on a BACKPLATE.
1 Operational Theory Model 6000A 1.6.1 Source Module Any one of three types of source modules may be used in your system. The system model designation identifies the source lamp (see Figure 1 for a list of codes). The QI (Quartz-Iodine) and D 2 (Deuterium Arc) sources are mounted in the source module which also contains the focusing lens.
Oscilloscope test points are available and are mounted on a bracket inside the housing for explosion-proof models; test points are available on the outside in the bottom for general-purpose units. An optional zero and/or span filter is located in this module also. Teledyne Analytical Instruments Part II:...
