How a dmm works
WebAs shown in Figure 1, a test current - typically a few mA - is sent out by the multimeter and the internal DVM (digital voltmeter) module measures the voltage drop across the component. Ideally you take measurements with the components out of circuit. You must be careful when measuring components in a PCB. WebA reading of 100.0 V on a digital multimeter with an accuracy of ±2% can range from 98.0 V to 102.0 V. This may be fine for some applications, but unacceptable for more sensitive electronic equipment. Accuracy may …
