  • Page 13: Main Features Of The Analyzer

    Photometric Analyzer Part I: Control Unit Main Features of the Analyzer The Model 5000B 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.

  • Page 14: Operator Interface

    1 Introduction Model 5000B Operator Interface All controls and displays on the standard 5000B 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.
  • Page 15 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 5000B models produce continuous readout from 0-10,000 ppm and then switch to continuous percent readout from 1-100 %.

Remote Calibration Protocol: To properly time the Digital Remote Cal Inputs to the Model 5000B Analyzer, the customer's controller must monitor the Cal Relay Contact. When the contact is OPEN, the analyzer is analyzing, the Remote Cal Inputs are being polled, and a zero or span command can be sent.
