Short LM385-2.5, adjust R3 for I

OUT=temp at 1µA/˚K

2.

Remove short, adjust R2 for correct reading in

centigrade

0˚F–50˚F Thermomemter

00551927

Calibration

1.

Short LM385-2.5, adjust R3 for I

OUT=temp at 1.8 µA/˚K

2.

Remove short, adjust R2 for correct reading in ˚F

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.
