To get time versus resistance change results with a digital bench multimeter connected to a computer, you will need to use special software designed for the purpose. This software can be found from a variety of sources, including the manufacturer of the bench multimeter. The software will enable you to measure resistance changes over time, as well as collect and analyze data for further processing.
