To have an absolute temperature reading, you must measure the temperature of
the terminal strip and then add to it the thermocouple temperature.
K-Type Equations:
Linear delta T range of ± 20°C. Approximation error is ±0.20°C.
Temp (°C) = 25.346 * X*1000 – 0.1114 + Terminal_temp
Linear delta T range of ± 40°C. Approximation error is ±0.83°C.

Tipping Bucket
This section describes how to physically connect the sensor and how to configure
the setup in X-Link.
The sensor used in this example is a standard switch closure tipping bucket. This
sensor closes a switch for each tip of the bucket and has two leads, polarity
doesn’t matter.
To wire it up, connect like so (The lead numbers are not marked with numbers;
this is just a reference.)
