NARRATIVE
            The thermocouple consists of two wires of dissimilar metals connected to a sensitive projection galvanometer. As heat is applied to the junction of the two wires, current will flow.

            Connect the thermocouple to the galvanometer and adjust the scale sensitivity so that the deflection will be less than full scale for the amount of heat that will be applied to the junction.
