5.1.1 Measuring the conductivity
1. Connect a conductivity measuring cell to the measuring instrument.
The conductivity measuring screen is displayed.
2. Adjust the temperature of the solutions and measure the current temper-
ature if the measurement is made without a temperature sensor.
3. Immerse the conductivity measuring cell in the test sample.
4. When measuring without temperature sensor: Enter the temperature of
the test sample with <><>.
5. Wait for a stable measured value.
The [AR] display indicator no longer flashes.
6. If necessary, select the measured parameter with <M>.
• Conductivity [µS/cm] / [mS/cm]
• Salinity Sal
• Total dissolved solids TDS [mg/l]
If necessary, set the TDS factor with <><> (see section 6.1.4
S
ETTING THE TDS FACTOR, page 26).
• Resistivity [MΩ ·cm]
Stability control (AutoRead )
During the measuring procedure, the stability control function is automatically
activated.
To ensure the high measurement accuracy of the measuring sys-
tem, measure with a current calibration or the correctly set cell
constant (see section 5.2 C
ALIBRATION, page 19).
