5 - Modules and models
The wireless settings are stored and retained in the radio module. Exchanging the measurement
module does not affect them, which allows easily exchanging the measurement module to a
recalibrated unit, especially with the T and T-RH models. Also some of the other settings are stored in
the radio module, e.g. the measurement intervals.
To detach the two modules, first grasp the measuring module on its locking latches and fully depress
them to release the latches. Then pull the measuring module straight out of the radio module. You may
need to wiggle the measuring module slightly to more easily overcome the friction caused by the two
O-rings. If necessary, support the radio module by holding it in place with your other hand at the same
time when pulling out the measuring module.
To join them, align the small embossed arrowheads on both modules’ housings (when they are aligned,
also the silver colored labels on both modules are on the same side). Then push the measuring module
straight into the radio module until the locking latches catch and click into place.
This manual has a chapter for each measurement and radio module. Refer to the modules suitable for
your module types.
