Page 7: Introduction
Introduction 1. Introduction 1.1 Overview The DirectLine® Sensor consists of an electronics module connected to a Meredian II ORP electrode that eliminates the need for pre-amps, transmitters, and analyzers in ORP applications. The modular electronics design can be separated from the electrode, allowing the electrode to be easily removed or replaced while retaining power to the electronics module. -
Page 8: Electronics Module
Introduction 1.2 Electronics Module The electronics module is loop-powered by 16-42 Vdc and will modulate its supply current from 4 mA to 20 mA, depending upon the ORP value that is measured by the Meridian II electrode. A 4-20 mA output connection is provided via a 6m cordset or a customer supplied cable used in combination with a field wiring connector. -

Page 20: Calibration
Calibration 4. Calibration 4.1 Calibration Diagnostics Introduction The manual standardization adjustment changes the zero offset diagnostics used by this system. This value is viewed as read-only information. It is good practice to observe this value after calibration. Monitoring the value over time will help you predict when the electrode will need to be replaced. -

To prepare an ORP standardization solution, dissolve 0.1 g of quinhydrone powder (available as Honeywell part number 31103015 for a 2 oz. bottle) in 5 cc of acetone or methyl alcohol (methanol). Add this to not more than 500 cc of a standard pH reference solution (buffer), about 1 part saturated quinhydrone to 100 parts buffer solution. -
