CommissioningLiquiline M CM42
6.5.1Types of calibration
•Two-point calibration
–With automatic buffer recognition:
You select the buffer type (e.g. DIN 19266). The device automatically recognizes the buffer during calibration.–With fixed buffer:
You select two buffer solutions from the menu.•Single-point calibration –You enter an offset.•Numeric input:
–You enter the slope, zeropoint and temperature.•Grab sample calibration
–You take a sample of the medium. The device determines a measured value while you analyze the sample in the laboratory.
Then you enter the laboratory measured value. The device calibrates on the basis of the laboratory value.6.5.2Calibrate
Proceed as follows to calibrate the sensor:1.2.3.4.5.6.
Remove the sensor from the process.Clean the sensor.
Press the soft key for \"CAL\".Follow the instructions in the menu.
Finish calibrating by switching back to the measuring mode.Install the sensor back into the process.
Your measuring point is now ready for operation.
!
Note!
•If calibration is aborted using ESC, or if the calibration is faulty, the system continues to use the original calibration data. A calibration error is shown as plain text on the display. •Any offset set is automatically deleted after accepting the calibration.

Disconnect Liquiline from the power supply and open the housing.Remove the cable connections from the module you want to replace.Pull out the two removal aids on the module until the stop (→å28).The module can now be easily removed from the DIN rail.
Slide the new module into the guides (→å29, →å30, →å31).
Push the two removal aids on the module in the direction of the DIN rail until the stop. This locks the module onto the DIN rail.
Connect the cables in accordance with the wiring diagram (see \"Wiring\").
Close the housing, connect the sensor and check that the entire measuring system is working correctly.
