WebWhat is a multimeter used for measuring? A digital multimeter is a test tool used to measure two or more electrical values—principally voltage (volts), current (amps) and resistance (ohms). ...Digital multimeters combine the testing capabilities of single-task meters—the voltmeter (for measuring volts), ammeter (amps) and ohmmeter (ohms). WebIn general, resistance is measured with a digital multimeter in the same manner as with an analog multimeter, and it’s a very simple process. The only difference is that the value is …
WebMay 25, 2024 · Digital current meters measure the very small voltage across a very low resistance (known as a "shunt") in series with the circuit being measured. If you open a digital multimeter (or an old analogue one that can measure high currents) you'll see the shunt especially on the highest current range. WebMar 9, 2015 · I think most low cost meters do the same (those with a most sensitive DC scale of 200mV). Thus you divide 200mV by the resistance scale setting to get the (constant) current used to measure the resistance. For example, at the 20kΩ scale setting, the current would be 200mV / 20kΩ = 10μA
