Web22 nov. 2024 · The test current for a typical DMM on the 200 ohm range is typically between 1 mA and 2 mA. For lower ohm ranges like 20 ohms or even 2 ohms the test current would need to increase to 20 mA and 200 mA. Specialty milliohm meters generally use test currents in the area of 100 mA to 200 mA and can sometimes be as high as 1A. WebIn general, the lower the capacitance measuring range of the digital multimeter (DMM), the better it is for electronics work: - Less expensive DMMs will only be able to measure capacitance down to the hundreds of microFarads (µF). - Medium-range DMMs will normally be able to measure down to a couple of nanoFarads (nF).
