Fluke 1586A - Thermistor Temperature Accuracy; Thermistor Measurement Characteristics

Product Overview and Specifications
Measurement Specifications 1
1-17
Thermistor Temperature Accuracy
Accuracy specifications are for 4-wire thermistor. When using 2-wire thermistor, add the number given in the table to the
specification for internal resistance. If the environment temperature is outside the specified range, increase the accuracy
specification by 25 % for every 1 °C outside the specified environment temperature range. Specifications do not include
sensor accuracy. The practical range of temperature measurement depends on the sensor.
