XLINK 500/100 Operations & Maintenance Manual page # 31
The key settings for thermistors are:
Measurement Type: Analog
Analog type: A or B
Equation to compute temperature (Celsius):
Steinhart((10000)*X/(VREF-X), A, B, C) (see table below for A, B, C)
Note: The 10000 is the reference resistor value in ohms.
Slope: 1.8; Offset: 32 to convert to Fahrenheit.

Campbell Scientific’s CS205 & CS107 temperature probe requires different wiring than th
e
above since it has a reference resistor built into the probe. The wires are connected as indicated
below on the left, and the equation will use the built-in template for CS205/107. The image on
the right indicates the probe’s internal wiring for
reference.
