6020 Analysis Unit, is versatile microprocessor-based instru- ment. Part I, of this manual covers the Model 6020 Explosion-Proof, Bulk- head Mount Control Unit. (The Analysis Unit is covered in Part II of this manual. The Control Unit is for indoor/outdoor use in hazardous environ- ment only.
• Internal calibration-Manual or Automatic (optional). Operator Interface All controls and displays on the standard 6020 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.
This function selects whether analyzer is autoranging or locked on one range. -Standby Places the analyzer in a sleep mode. WARNING: The power cable must be disconnected to fully remove power from the instrument. Part I: 1-3 Teledyne Analytical Instruments...

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 6020 models produce continuous readout from 0-10,000 ppm and then switch to continuous percent readout from 1-100 %.

This function helps select whether the following span cycles will be done using the span flag or with a prepared sample on the fluid reservoir of the 6020. Before using the span flag, its span value has to be found out by first calibrating the analyzer with a known concentration solution poured into the reservoir.
Operation 3 3.3.9 Hold/Track Setup The 6020 has ability to disable the analog outputs and freeze the display while undergoing a scheduled or remote calibration. The 6020 will track changes in the concentration if calibration is started through the front panel.

3 Operation Model 6020 The Analyze Function Normally, all of the functions automatically switch back to the Analyze function when they have completed their assigned operations. The Escape key in many cases also switches the analyzer back to the Analyze function.
Normally the Model 6020 is factory set to default to manual range selec- tion, unless it is ordered as a single-application multiple-range unit (in which case it defaults to autoranging).

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 6020 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.
