5.3 Transducer plug-in detection
Before the module can be in active measurement mode for a selected chan-
nel, the module must have recognized that a transducer has been plugged in.
The module faultlessly detects when a transducer is plugged in or removed, if
plug-in detection has been implemented through a TEDS module or a jumper.
The jumper can only be installed on a 1-wire lead.
