5.1. Connecting into the current loop
In hazardous areas you should take note of the appropriate
regulations, conformity and type approval certificates of the
DT9000 and other instruments are connecting in the
current loop (e.g. power supply, transmitter, etc.).
The connection must be carried out by trained and
authorised personnel only!
There are two different cases for the current loop to be
