10.2.2 Measuring
You can carry out conductivity measurements as follows:
Selecting the displayed
measured variable
You can switch between the following displays with <MODE> :

Conductivity [
μ
S/cm] / [mS/cm]

Resistivity [k
Ω
·cm] / [M
Ω
·cm]

Salinity SaL [ ]

Total dissolved solids TDS [mg/l]
The factor to calculate the total dissolved solids is set to 1.00 in the fac-
tory. You can adjust this factor to meet your requirements in the range
of 0.40 to 1.00. The factor is set in the menu,
Measuring / TDS factor
setting... .
Note
The selection of the measuring cell and setting of the cell constant is
made in the conductivity measuring menu (see page 142). The cell
constant to be set must either be taken from the operating manual of
the measuring cell or is printed on the measuring cell.
With ID conductivity measuring cells, the last used cell constant and
other settings are stored in the sensor (see page 18).
1 Perform the preparatory activities according to page 139.
2 Immerse the conductivity measuring cell in the test sample.
