8.4.3.2 Change measuring range

Fig. 8.18
Depending on whether a conductivity or product measuring range was set previously, this will be
displayed on the second line. Use the arrow keys to choose between concentration and
conductivity measurement. One of the functions below is called up using the SEL key.

8.4.3.4 TCα setting (in the conductivity measuring ranges)
It is necessary to set the temperature compensation because the conductivity of the
material being measured is very much influenced by temperature inter alia.
As conductivity measurement is often used in industrial applications to determine
NOTE
concentrations of solutions, and because the actual conductivity at specific temperatures is
not always of interest, the conductivity is related to a reference temperature of 20 °C for
example.

It is possible to determine the temperature coefficient automatically and this is described in
chapter 8.5.3.

If the "change measuring range" function is called up, the
menu shown is displayed.
In addition to the product measuring ranges, the raw

The reference temperature 0°C can only be selected for
conductivity measurement!
The TCα value can be set between 0% /K and 5 %/K.
