The conductivity basic module can be used as an independent conductivity
measuring cell. For this purpose, unscrew the DO module and close the open
plug connection with a closing cap.
The DO module is connected to the conductivity basic module via a water-
tight, three-pole plug connection. The conductivity basic module measures
the temperature, which is required for the determination of the DO content.
For this reason the DO module only works in conjunction with the conductivity
basic module.

Instrument identification
A series number is printed on both ConOx modules. Keep these numbers
ready if you have questions to ask the WTW service department.
The series numbers contain the following information:
