NOTE NOTE NOTE NOTE NOTE:
1) Don’t run input wires together with power
cables.
2) Pay attention to the line resistance; an 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.

1) Do not run input wires with power cables.
2) For TC wiring use proper compensating cable
preferable shielded (see "Appendix B" of the
LHI or LHL user manual).
