*To calibrate adjust R2 for 2.554V across LM336.
Adjust R1 for correct output.
*Select R3 for proper thermocouple type
Adjustments: Compensates for both sensor and resistor tolerances
1. Short LM329B
2. Adjust R1 for Seebeck Coefficient times ambient temperature (in degrees K) across R3.
3. Short LM335 and adjust R2 for voltage across R3 corresponding to thermocouple type.
