Measuring the electrical resistance (ohms) of motors, compressors, and other electrical devices in HVAC systems may seem straightforward. But when the measurements of zero (0) or “OL” (overload) come ...

Most precision digital multimeters (DMMs) and many source measurement units (SMUs) offer both two-wire and four-wire resistance measurement capabilities. However, these two techniques are not equally ...

Don�t heap all the blame for a wrong measurement on the DMM. There can be several less obvious sources of the errors. Testing assemblies and components usually includes checking the continuity of ...
