Vernier Software and Technology's LabPro® data acquisition device1 has the cursorily documented2 ability to measure resistance. Here we describe how to build a resistance probe and how to configure Vernier's Logger Pro® data acquisition software to automatically detect and understand the probe. We discuss the range, accuracy, and limitations of this ohm-meter. When this probe is used with voltage and current probes already available from Vernier, the LabPro may be used as a digital multimeter.

Logger Pro 2.2.1 uses a quite different approach for identifying and configuring probes. Files and instructions for using this resistance probe with Logger Pro 2.2.1 can be found on our website;∼bodegom/ohmmeter.
This is not true for Logger Pro 2.2.1, since this version requires specific probe configuration files. The files needed to use the LabPro as multimeter are available on our website;∼bodegom/ohmmeter.
