CHECKOUT

For best results, allow the sensor to absorb the air

moving through the room for a minimum of twenty

minutes before taking a resistance measurement.

1. Use an accurate thermometer (+/-1ºF[0.5ºC]) mea-

sure the temperature at the sensor location.

2. Remove one wire from one of the sensor's wiring

terminals. Use an ohmmeter to measure the resis-

tance across the sensor. Verify the sensor accu-

racy with the temperature/resistance in Table 1.

CALIBRATION

The sensor is calibrated at the factory and cannot be

recalibrated in the field.
