4.4 Conductivity
4.4.1 General information
You can measure the following variables:
z Conductivity
z Specific resistance
z Salinity
z Total dissolved solids (TDS)
The measuring instrument is supplied with the following functions:
z AutoRange (automatic switchover of the measurement range). If a
measuring range is exceeded, AutoRange causes the measuring
instrument to automatically change to the next higher measuring
range and back again. Therefore, the instrument always measures
in the measuring range with the highest possible resolution.
z The AutoRead (stability control) function for checking the stability of
the measurement signal. The display of the measured parameter
flashes until a stable measured value is available.
Temperature
measurement
The TetraCon 325, KLE 325, LR 325/01 and LR 325/001 conductivity
measuring cells have an integrated temperature sensor.
Preparatory activities Perform the following preparatory activities when you want to measure:
Note
The selection of the measuring cell and the setting of the cell constant
is done in the measurement settings menu for conductivity (see section
4.4.4). 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.
1 Connect a conductivity measuring cell to the measuring
instrument.
The conductivity measuring window is displayed.
2 Check whether the Measuring cell and cell constant settings
are suitable for the connected conductivity measuring cell. If
necessary, correct the settings.
