* Select R3 for proper thermocouple type
Adjustments : compensates
and resistor tolerances.
1. Short 1N4568.
2. Adjust R1 for SEEBECK coefficient times
ambient temperature (in degrees K) across
R3.
3. Short LM135 and adjust R2 for voltage
across R3 corresponding to thermocouple
type.

* Select R3 and R4 for proper thermocouple
Adjustments :
1. Adjust R1 for the voltage across R3 equal
to the SEEBECK coefficient times ambient
temperature in degrees Kelvin.
2. Adjust R2 for voltage across R4 correspon-
ding to thermocouple.
