*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

away from the end tip (2) of a thermocouple, the (ambient) temperature (3) difference may lead to a faulty
temperature process value (PV).
