* Select R3 for proper thermocouple type
Adjustments : compensates for both sensor
and resistor tolerances.
1. Short 1N4568.
2. Adjust R1 for SEEBEC K 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 coeffi cient times ambient
temperature in degrees Kelvin.
2. Adjust R2 for voltage across R4 correspon-
ding to thermocouple.
