Digital temperature and humidity tools are a modern, efficient way to measure and maintain your environment. Keep them up-to-date for the most accurate readings.
There are five basic steps to perform as listed below:
Place the reference probe and the UUTs in the temperature source in close proximity to one another.
Connect the leads to the readout(s) ensuring proper 2-, 3-, or 4-wire connection.
Measure the reference probe and determine the temperature.
Measure and record the resistance of the UUT(s).
Fit the data.
Some readouts simplify the technique by combining or eliminating some of the steps. In the following discussion, we will consider an application involving PRT characterization by comparison to an SPRT.
