Checking the conductivity display

The conductivity display of the LMI02 can be checked with the conductivity simulator for
LMIT08 (item no. 289190) or with a calibration box for multronic (item no. 255195). It is
also possible to check this by dipping the conductivity probe into a sample solution of
known conductivity.
The conductivity probe should be brought to 20°C in order to check the conductivity
display and the current output.
When using a simulator, the ↵ key can be pressed to show the uncompensated
CAUTION
conductivity value (a * symbol appears in front of the conductivity display). The current
output is also adjusted to the uncompensated value.
