WebTo measure resistance: 1. Turn power to circuit OFF. If a circuit includes a capacitor, discharge the capacitor before taking any resistance reading. 2. Turn digital multimeter dial to resistance, or ohms, which often shares a spot on the dial with one or more other test/measurement modes (continuity, capacitance or diode; see illustration below). WebI checked one of the USB ports of a computer at work. I probed pins 1 and 4 with a multimeter in DC mode. The PC's fan started spinning fast, then blue screen of death. Fortunately the mobo was not damaged. But I still don't understand what went wrong. Never repeated the experiment again. \$\endgroup\$ –
