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.
