WebThe ohmmeter function of a multimeter measures the resistance to current flow. This measurement is given in units called ohms. If an electrical circuit is "short-circuited," then its resistance is zero or near zero ohms. If a circuit is open, then it has infinite resistance and there is no current flow. WebWith the help of this article, you will be able to know how an ohmmeter works. Best Values. True RMS Digital Ohmmeter. It can measure DC Volt 60.0mV 1000V, AC Volt 60.0mV 7500V, and Resistance 600 ohms with high accuracy. Its Capacitance: 9.999nF/99.99%, Temperature: -20°C to 1000°C, Frequency: 9.999Hz/9.999MHz.
