• Setting the cell constant (default: 1.000×100 m
-1
)
A cell constant is set for each conductivity cell. To measure conductivity correctly, the cell
constant of the conductivity cell must be set in the instrument.
1. Press the
key to enter the setting mode.
2. Press the
keys to select the "CELL" (cell constant setting) and then press
the
key.
3. Press the
keys to select the digit number of the cell constant of the
conductivity cell and then press the
key.
4. Press the
keys to enter the number of the cell constant of the conductivity
cell and then press the
key.
Note
・
The unit used for the cell constant corresponds the unit set in “ Setting the conductivity unit
(default: S/m) ” (page 19).
・
Match the unit indicated on the conductivity cell to the unit set in the instrument.

The cell constant may fluctuate depending on conditions of use. Check and calibrate the
conductivity cell about once a year (“ Checking and calibrating the conductivity cell ” (page
47)).
