Calibration
1. Short LM385-1.2-N, adjust R3 for IOUT= temp at 1.8μA/°K 2. Remove short, adjust R2 for correct reading in °F
Figure 24. 0°F−50°F Thermometer Adjustment Procedure
1. Adjust TC ADJ pot until voltage across R1 equals Kelvin temperature multiplied by the thermocouple Seebeck coefficient. 2. Adjust zero ADJ pot until voltage across R2 equals the thermocouple Seebeck coefficient multiplied by 273.2.
