Set the temperature coefficient α of the water sample in the
"meas. parameter setting?" setting menu (related to 25 °C. Arrow
keys!)
Set the temperature coefficient α of the water sample at the
reference metering equipment (to the same value)

Select the first menu option in the "calibration cc" setting menu
and press Enter
the temperature of the water sample must remain constant within
±0.5 °C for 20 min. and the measured conductivity value must
not fluctuate
Remove a sample from the water and determine the electrolytic
conductivity using reference metering equipment (stir for 30 s with
its sensor)
Enter the measured conductivity reference value in the second
menu option under "LF" (arrow keys!) and press Enter
"please wait" is displayed for a few seconds. The DULCOMETER
D1C then displays the current calculated cell constant.
The new cell constant is accepted when you press Enter to exit
the last menu option ("calibration cc - cc = ..."). If you do not
want to accept the new cell constant, exit this menu option with
the back key.
b) Calibration with calibration solution
Important precondition: You need a calibration solution of the
corresponding accuracy (better than 1 % absolute reproducibility;
at least 250 ml).
CAUTION
Take the necessary precautions when dismantling the sensors
(safety gear...)!
