Conductivity measurement is very temperature dependent.

The factory set-up is 2,0%/°C.

This means that the AFIx will automatically compensate with this fac-

tor. If the temperature dependence is known for the media this factor

must be set. However if the factor is unknown, it is recommended to

use an average from above table.

It is possible to adjust the temperature compensation factor from 0,0 …

5,0 %/°C.

Configure the temperature compensation by the touch screen:

Configure the range by the touch screen:

Configuration by the FlexProgram and FlexProgrammer please see

HELP in the FlexProgram.

Concentration output can also be selected by the touch screen or pro-

grammed by the FlexProgram.

Programming of the display colours, warnings and relays can be done

by the touch screen (see page 8 and 9) or by the FlexProgrammer.
