These modern-day tape measures consolidate the functions of voltmeters, ammeters, and ohmmeters into a single unit. As one of most widely-used electronic testing instruments, the digital multimeter (DMM) is more commonly known as the modern-day tape measure. But instead of being able to handle a single function (i.e., linear measurement), DMMs consolidate the functions of multiple instruments, such as voltmeters, ammeters, and ohmmeters into one unit. DMMs are used in electrical engineering design, maintenance, quality control, inspection, and/or any application requiring electrical servicing and diagnostic testing. A basic DMM works with energized and de-energized electrical circuits and measures alternating current (AC), AC […]
