How a digital multimeter works
Web5 de fev. de 2024 · Place the dial to the diode symbol and connect the DMM parallel to the diode. Once the multimeter is connected to the diode in this configuration, the multimeter passes a small current through it. Diodes only conduct in a forward-biased region, and connecting the diode in such a manner displays a forward voltage drop. Web15 de set. de 2013 · Hi Nick; I know it is possible to make a simple model. I am sure you have no problem to program it. The old digital model have a "scale or range" selection knob. You select 100 mV, 1 V, 10 V, 100 V for example. The selector will select an op-amp circuit to "translate" min to max ==> 0 - 5 V into the analog pin.
