*1 Use the shielded compensation lead wire.
*2 Use the shielded cable.
Use the compensation lead wire for the cable of a thermocouple. The shielded cable cannot be used. If the
compensation lead wire is not used, and when the cold junction temperature compensation resistor (1) is
away from the end tip (2) of a thermocouple, the (ambient) temperature (3) difference may lead to a faulty
temperature process value (PV).
