"Web15 de out. de 2024 · For older meggers, the method was a hand-crank generator that could build up a huge voltage, sometimes well above 1000 volts. For digital meters, the step-up is done with a DC-DC voltage converter. These can still yield a high voltage, although 1000 volts is usually about the largest typical voltage on a digital mega-ohmmeter. Figure 2. " - How an ohmmeter works
