4.2   Basic Settings using the HART Communicator DXR 275 

The FEC 12 allows calibration in % only. A remote calibration from the handheld
allows, e.g. technical units to be displayed. If a recalibration is to be carried out, then
a reset should be done first. The parameters of the electronic insert must not be
locked, see above!

Note!

When calibrating the FEC 12 electronic insert, the following sections will assume the
operating steps given below. They apply to all instructions and will, therefore, no
longer be given in this manual:

First step: Move from the 

"MATRIX GROUP SEL."

 menu to the next higher menu with the

 arrow key. 

Last step: Return to the 

"Online"

 menu with F3 [HOME].
