1) Don't run input wires together with power cables.
2) Pay attention to the line resistance; a high line resistance may
cause measurement errors.
3) When shielded cable is used, it should be grounded at one
side only to avoid ground loop currents.
4) The resistance of the 3 wires must be the same.
