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.
