Temperature Sensor Checkout
1. Overall accuracy for the sensor is at least + 2 F over the range shown.
2. As you compare a thermistor resistance (or input voltage) reading with the “actual” temperature indicated by the thermometer, be sure to
consider the location and precision of the thermometer when you decide whether or not the thermistor is out of specified accuracy.
3. The thermistor resistances given do not account for the self-heating effects that are present when connected to the UCM. A connected
“operating” thermistor will read a slightly lower (less than 1%) resistance.
