Wiring thermocouples and thermal resistors
Connect the thermocouple to the supply lines directly at the reference junction, or indirectly
using compensating lines. Wire the supply lines to the corresponding terminals of the
module.
You may use cables made of any material to wire the thermal resistor to the module
terminals.
