NOTE NOTE NOTE:
NOTE NOTE
1) Don't run input wires together with power cables.
2) Pay attention to the line resistance; a high line
resistance (higher than 20 Ω/wire) may cause
measurement errors.
3) If shielded cable is used, it should be grounded
at one point only.
4) The resistance of the 3 wires must be the
same.
