Centigrade Calibrated Thermocouple Thermometer
DS005698-12
Terminate thermocouple reference junction in close proximity to LM335.
Adjustments:
1. Apply signal in place of thermocouple and adjust R3 for a gain of 245.7.
2. Short non-inverting input of LM308A and output of LM329B to ground.
3. Adjust R1 so that V
= 2.982V
@
25˚C.
OUT
4. Remove short across LM329B and adjust R2 so that V
= 246 mV
@
25˚C.
OUT
5. Remove short across thermocouple.
