3.3 Configure the 3100
Before operating the 3100, or whenever you change cells, you must configure the 3100 to match
the cell used. You must enter the manufacturer’s stated (or your manually calculated) cell
constant (K) as shown below (Cell Constant).
The default configuration is as follows:
•
Cell constant of K = 1
•
Temperature compensation corrected to 25°C using a coefficient of 1.91%/°C.
If you are using a cell with a cell constant of K=1 (such as the YSI 3252, 3253, 3254, 3401,
3403, 3417, or 3445), the cell constant is already set correctly. If, however, you are using a cell
with a different cell constant (such as the YSI 3256, 3255, 3402, 3418, 3440, or 3446), you must
enter the manufacturer’s stated cell constant for the cell that you are using (K= 0.1, 10.0 etc.) as
shown below (Cell Constant).
