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 <M>:
z Conductivity [ µS/cm] / [mS/cm]
z Specific resistance [k Ω
·cm] / [M
Ω
·cm]
z Salinity SaL [ ]
z 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 can be set in the TDS measuring menu.
AutoRead criterion The measuring instrument checks the stability of the measured value
on the basis of the temperature measurement. For identical measure-
ment conditions, the following applies:
1 Perform the preparatory activities according to section 4.7.1.
2 Immerse the conductivity measuring cell in the test sample.
