Honeywell 9782 Series Entering the Cal Factor for Each Cell, Procedure for Entering Cal Factor

Conductivity/Resistivity Analyzer/Controller

8.3 Entering the Cal Factor for Each Cell

Introduction

Each type of cell has an associated cell constant; this number is part of the cell model number. The constant for each cell is entered during I/O setup. However, for greater precision, every Honeywell cell is individually tested at the factory, and a calibration factor unique to that cell is determined. The cal factor for a cell can be found on the plastic tag hanging from the cell lead wires.

ATTENTION

Any time you replace a cell, even with another cell of the same type, enter the cal factor for the replacement cell.

Procedure

To enter the cal factor for each cell, follow the procedure in Table 8-1.
