When thermocouples and Pt100/ Pt1000 sensors are used, it is recommended to connect one
of the C terminals to Earth (all C terminals are internally connected). It will minimise noise and
sensitivity if touching terminals when measuring.
Twisted pair or/and shielded cable on input, is recommended to achieve specified accuracy
and for optimisation of immunity-noice.
