9 Calibration
9.3 Calibration default settings
The calibration routines of the device can be enabled/locked in the calibration default settings. To do this,
you must first log in on the device as "Admin".

In addition, the way the temperature is acquired can be set:
•
Automatic temperature acquisition: During the calibration, the device acquires the calibration
measuring points automatically by scanning past the operation or reference temperature. This is only
possible when the JUMO digiLineCReither measures the temperature itself with an integrated sen-
sor or acquires the temperature of the test solution from a master via an interface.
• Manual temperature acquisition: This setting can be selected if you wish to trigger acquisition of
the calibration measuring points manually by pressing a key during calibration of the temperature
coefficient.
9.4 Calibration of the JUMO digiLine CR with IO-Link interface
Conductivity sensors with JUMO digiLine electronics can be calibrated using the JUMO DSM software
on the PC in the case of device versions with an IO-Link interface, or via local operation of the device in
the case of a device versions with a display. The calibration values are calculated in the JUMO digiLine
electronics of the sensor. The calculated calibration values and the data in the calibration logbook are
saved in the JUMO digiLine electronics following successful calibration.
The procedure for calibrating with a PC is described in the operating manual of the JUMO DSM software.
9.5 Calibration via local operation in device versions with a display
CAUTION!
The conductivity measurement by the device has 4 measuring ranges.
During calibration, it is necessary to ensure that all measuring ranges used are taken into account.
 Calibrate all 4 measuring ranges individually. For the relative cell constant, the mode for the relative
cell constant can also be set to 1 cell constant for all measuring ranges in the configuration of the
conductivity input. If you select this setting, you only need to calibrate the relative cell constant once
for all of the measuring ranges.

NOTE!
To perform calibrations, you must log in on the device as a user with calibration rights. By default, the
"Administrator" has calibration rights.

Calibrating the relative cell constant
NOTE!
Depending on the mode set for the relative cell constant in the configuration of the conductivity input,
either a common relative cell constant is used for all 4 measuring ranges or a relative cell constant is
determined separately for each measuring range
