l
The plug connection and the inside of the closing cap must be clean.

Make sure that the DO module and conductivity basic module are screwed
together tightly. When mounted, the cap nut of the DO module has to be
screwed on up to the stop.
Before screwing on the DO module, check the following points:
l
The sealing (3) must be clean and evenly positioned in the groove.

The plug connection must be dry on both sides.
Screwing on the
DO module
Position the DO module (1) on the conductivity basic module and carefully
and with slight pressure turn it until the guiding nib on the DO module locks
in place in the corresponding groove on the conductivity basic module.
Subsequently tighten the cap nut (2) up to the stop. The thread only snatches
if the DO module was correctly positioned.
