Balancing Indoor/Outdoor Temperature Readings

Balancing potentiometer for the thermometers.

The control console includes a balancing potentiometer to make the OUT TEMPERATURE agree with the IN TEMPERATURE. The value is mostly cosmetic since a 10°F error only yields a 1% error. Because overall equipment accuracy is 5%, chasing this 1% is not too significant. Ensure IN and OUT probes are at the same temperature for 10 minutes. OUT is on the UMBILICAL cord; IN is at the control console. Turn the adjuster located to right of the thermometer

CLOCKWISE to DECREASE OUT reading; COUNTER-CLOCKWISE to INCREASE OUT.
