Resistance vs. Temperature Tables
The following table lists the Resistance vs. Temperature characteristics of the ET series
thermistor probes as they relate to use with the SmartReader Plus 1, 2, 4 and 8 loggers.
For each thermistor probe model the table documents the complete set of temperature
readings and corresponding thermistor resistances possible for the logger's eight most
significant bits. The 12-bit reading values are normalized to a full scale value of 255; this
allows the same equation to be used for both 8 and 12 bit loggers. The least significant bit of
the 12-bit value is weighted 0.062 (255/4095).
