Calibrating the
conductivity me-
ter
When particularly high demands are placed on the cleaning and final
rinse result, e.g., in chemical analysis, the conductivity meter can be
calibrated with the Adjust conductivity modulefunction. The measuring
system is calibrated from DI water to cold water in the conductivity
measuring range.
Conductivity meter calibration can only be carried out if there are
no load carriers in the wash cabinet.
The wash cabinet should be rinsed with DI water to prevent high
measured values due to lye splitting.
 Press the Adjust conductivity modulebutton.
The DI water measurement is carried out.
The message Please wait... and the current process step appear in
the display, e.g., Measurement active.
At the end of the measurement, the DI water conductivity: Actual is
displayed together with the input screen for the manually measured
value.
The infeed side door is released for the manual measurement.
 Open the door and perform the manual conductivity measurement.
 Close the door.
 Press the button next to the DI water conductivity: Newparameter to
open the on-screen keyboard.
 Enter the measured value using the on-screen keyboard and con-
firm with OK.
Measured values with decimal places need to be mathematically
rounded.
 Press the OK button.
The cold water measurement is carried out.
 Perform the same work steps as for DI water if the message Cold
water conductivity: Actual is displayed.
The values entered for Conductivity... New are taken over by the con-
trol module.
The Machine functions reappear in the display.
You can cancel the conductivity meter calibration using the but-
ton in the footer. The message Adjustment of conductivity module un-
successful. Please repeat. will appear on the display.
