4.7.2 Measuring
You can carry out conductivity measurements as follows:
Selecting the
displayed
measured variable
You can switch between the following displays with <MODE>:
 Conductivity [ μS/cm] / [mS/cm]
 Resistivity [ Ω·cm] / [MΩ·cm]
 Salinity SaL [ ]
 Total dissolved solids TDS [mg/l]
The factor to calculate the total dissolved solids is set to 1.00 in the
factory. You can adjust this factor to meet your requirements in the
range of 0.40 to 1.00. The factor can be set in the TDS measuring
menu.
Stability control The Stability control function checks the stability of the measurement
signal. The stability has a considerable impact on the reproducibility of
measured values. The display of the measured parameter flashes until
a stable measured value is available.
Independent of the setting for automatic Stability control (see page 35)
in the System menu, you can start the Stability control function
manually at any time.
1 Perform the preparatory activities according to page 62.
2 Immerse the conductivity measuring cell in the test sample.

1 If necessary, select a channel (measured value) with <
▲><▼>.
2 Freeze the measured value with <SC>.
The display switches to the display of the selected channel as
necessary.
In the status line, [SC] is displayed.
