I was thinking about using LOOKDOWN / LOOKUP but the steps would be in 10 degree increments. The resistance in 25 °C is 10K (+- 1%). P/N 1600-10K Thermistor The enclosed negative temperature coefficient (NTC) thermistor, p/n 1600-10K, works by translating temperature into resistance, with resistance decreasing as temperature increases (hence the ânegative coefficientâ).
