Thermistor 100 Kohm range, 0 to 99.99K or 10 ohms
1 Megohm range, 0 to 999.9K or 100 ohms
For other sensors, such as RTDs, thermocouples, AD590/592 and
LM35/135/335 sensors, the resolution is 0.1 ºC.
Display Resolution
Thermoelectric Cooler temperature and set-point temperature in ºC or ºF
(user-selectable) with an RTD, thermocouple, AD590/592 and LM135/335.
For a thermistor, the display is in Kohms.
Display
Two 4 digit LED displays, RED - for actual temperature
GREEN - for set point temperature

Higher and lower temperatures can be measured depending upon the
sensor type. Please refer to Appendix A for details on the
temperature ranges available for each sensor type and an example of
a custom sensor type.
Thermistors can operate on one of two ranges (0 to 99.99 Kohms and 0 to
999.9 Kohms). Integrated temperature sensors (AD590/592 and
LM35/135/335) operate from: -50ºC to 150ºC.
