The TCR option

The Resistance Temperature Coefficient option integrates sample temperature control as well as automated injected current control and resistance calculations. Integrated with a thermal chuck system, the test automatically sweeps temperatures over a wide range without moving the test tips.
Measurements are taken at each target temperature and the results are plotted on a graph. The TCR is expressed in parts per million (PPM). Users define the temperature range, steps, and delay for each test point before taking a measurement. A variety of thermal chucks are available to set the range and resolution from room temperature to 300°C, with 1° resolution.
Data can be printed or exported to a spreadsheet for further analysis.
