POINT
Use a compensating lead wire for a thermocouple cable. Otherwise, when there is
a distance between the cold junction temperature compensation resistor and the
end part of the thermocouple, the measured value (PV) may be abnormal due to
the ambient temperature difference.
(b) Micro voltage input
*1: Use a shielded cable.
(c) Voltage input
