Conductivity/Resistivity Analyzer/Controller

1.3.2 Online Displays

Introduction

The online displays available when the operator presses the DISPLAY key depend on the number of cells connected to the Analyzer/Controller, and on the special features used. The instrument’s tagname (or other configurable text) is at the top of the screen for all displays except the digital clock and the AutoClean Sequence display. Every display includes an “alarm stripe”, a line dedicated to displaying process alarm messages, status messages, and system diagnostic messages, whenever any are active.

Individual cell display

For each cell connected to the Analyzer/Controller an online display similar to Figure 1-2 is provided. The information on this display includes:

∙the value measured by the cell, with the appropriate unit of measure filled in

∙an indication of whether the value is temperature compensated (TC) or not compensated (NC); the display can be toggled between displaying compensated and raw data using the F1 function key

∙the temperature in °C

∙if the value displayed is a percent concentration (9782C-W0 only), the chemical will be identified above the alarm stripe

In addition of the function key used to toggle the temperature compensation display, function keys are available to access calibration displays (without going through the menus), and to acknowledge alarm stripe messages.
