Web30 de jul. de 2024 · Mega ohmmeter (Megger) Megger instrument measures Megaohms and Giga-ohms resistance in a circuit. It is suitable for insulation resistance measurement. The measuring range of the meter is 0.5Ω to 2, 000, 000 MΩ. Digital Ohmmeter; This is also known as a digital multimeter for resistance measurement. WebThe prefix "meg" describes a numerical value of 1,000,000. In the case of an ohmmeter that value is also described in ohms. A megger will read a wire or motor windings in Megohms, where 1 Megohm is equal to 1,000,000 ohms. In order to read such a high resistance value the meter must be capable of generating a very high voltage.
