NOTE
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.
