Connection
4-wire mode
• The shieldings of the cables connected to Pt100 and to
the current loop must be connected with each other.
(see also “Application
example”)
Be careful the polarity of the cables.
The most accurate measurement can be achieved by the 4-
wire operating mode, as the cable resistances and their
possible asymmetry will not cause measuring errors.
In order to ensure accurate measurement its usage is
absolutely recommended.
