    en.wikipedia.org/wiki/Megohmmeter

    Megohmmeter M1101M. A Megohmmeter or insulation resistance tester, is a special type of ohmmeter used to measure the electrical resistance of insulators. [1] Insulating components, for example cable jackets, must be tested for their insulation strength at the time of commissioning and as part of maintenance of high voltage electrical equipment and installations.

    Due to electromagnetic interference, the first Megger insulation testers were built as two separate boxes – one for voltage generation, and one for measurement. They were later integrated into a single device in a Bakelite case, with special foldable handle for driving the dynamo. The most popular was the so-called "Wee Megger" (voltage up to ...

    A multimeter (also known as a volt-ohm-milliammeter, volt-ohmmeter or VOM) [1] is a measuring instrument that can measure multiple electrical properties. [ 2 ] [ 3 ] A typical multimeter can measure voltage , resistance , and current , [ 4 ] in which case can be used as a voltmeter , ohmmeter , and ammeter .

    This also led to a significant cost saving by eliminating the high voltage multiplier resistors. As an ohmmeter the Model 8 Mark II measures from 1 Ω up to 20 MΩ in three ranges. The instrument has an accuracy of ±1% of FSD on DC current ranges, ±2% of FSD on DC voltage ranges, ±2.25% of FSD on all AC ranges and ±5% of reading (at centre ...

  9. Light-emitting diode physics - Wikipedia

    en.wikipedia.org/wiki/Light-emitting_diode_physics

    An LED begins to emit light when more than 2 or 3 volts is applied in the forward direction. The reverse bias region uses a different vertical scale from the forward bias region to show that the leakage current is nearly constant with voltage until breakdown occurs. In forward bias, the current starts small but increases exponentially with voltage.
