A multimeter is a tool that is used to take measurements of electrical circuits. No matter what type of multimeter you own, you can probably test resistance and voltage with it. When your multimeter seems like it is not working correctly, there are a number of things you can do to test ...
3) Ohmmeter zero: short connect the red and black meter pen. Adjust the zero resistance knob to make the pointer point to the zero scale of the ohmmeter. If the "Ohmzero" button can't be turned right, after all, the battery in the meter should be replaced. 4) Measurement reading: la...

A resistance is a DC resistance, which can be measured with an ohmmeter. If there is a capacitor in the signal path we measure nothing. With a voice coil of a speaker we can measure a DC resistance. With a digital multimeter DMM resistances can be measured easily, but we cannot measure...
