Abstract
A single handheld multimeter device includes two or more independent measurement channels that are completely electrically separated and independent from one another. Each measurement channel has its point of reference, typically configured to be coupled to the ground. Measurements by the two or more independent measurement channels can be conducted concurrently, and the measurement results of the two channels can be processed and displayed together.
