Measuring ranges 1 to 4 for the CR input
Measuring range selection
On device versions with an RS485 interface for JUMO digiLine, the individual measuring ranges are ac-
tivated by the master (JUMO AQUIS touch S/P). The master must be configured appropriately by the
user (see documentation for JUMO AQUIS touch S/P).

nominal cell constant of the conductivity sensor (can be read
from the sensor nameplate)
Explanation
Type of temperature compensation
applicable only to "TC linear" and "TDS" compensation
The temperature coefficient is a measure of the temperature de-
pendence of the electrolytic conductivity of a liquid. It is used to
compensate for the effect of temperature when measuring the
electrolytic conductivity. If it is known, the temperature coeffi-
cient can be entered here or, if it is not yet known, determined
by the calibration.

(conductive)", page 47
Unit in which the conductivity is displayed
only for TDS compensation or customer-specific lineariza-
tion
Unit for the process variable to be displayed for TDS measure-
ments or when using customer-specific linearization (e.g. ppm
or mg/l)
Correction value added to measured value
