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 … WebFeb 8, 2024 · Measuring resistance and “ringing out a circuit” Measuring resistance values can easily be done with a DMM. The unit’s battery pushes current flow through one meter lead and into the circuit. The current then flows from the circuit into the opposite test lead and back into the meter battery.

WebDMMs measure down to high as 300 MΩ (300,000,000 ohms). Infinite resistance (open circuit) is read as “OL” on the Fluke meter display, and means the resistance is greater than the meter can measure. Resistance measurements must be made with the circuit power off—otherwise, the meter or circuit could be damaged. Some DMMs provide protection WebDescription The digital multimeter or DMM offers two methods for measuring resistance: 2–wire and 4–wire ohms. For both methods, the test current flows from the input HI … dr song chon
