1
Use a single thermocouple wire, spade lugs, spade-lug crimping tool, and mini-thermocouple connector to
make a wire assembly. Crimp the chromel spade lugs to the chromel wire to create 16 positive spade lugs.
Crimp the constantan spade lugs to the constantan wire to create 16 negative spade lugs.
2
Use the thermocouple wire, spade lugs, and spade-lug crimping tool to make 16 wires with bare leads on
one end and the spade lugs on the other end. Crimp the chromel spade lug to the chromel wire and the
constantan spade lug to the constantan wire.
3
Assemble the barrier strips and barrier strip jackets as indicated by the manufacturer.
4
Connect the wire assembly with the mini-thermocouple connector and 16 wires to the barrier strip.
