What is the Ohm meter? Ohmmeter is a device used to measure electrical resistivity. Types of ohmmeter are available in two analog (digital scorpion) and digital models. An inexpensive high-voltage device requires an internal voltage source to measure the resistance. The Ohm meter transmits current from the circuit and then measures the voltage drop. The output value resulting from the splitting of the voltage drop is on the current of the same resistance. The Ohm meter value depends on the performance, manufacturer and measurement accuracy. Many multimeters measure the ohm value. The most important types are: micro-ohm meter, millimeter-ohm meter, resistor meter, migraver (insulation tester)
Earth Tester is a device for measuring ground resistance. The tester's arrests usually have three connections, which can be connected to the ground using a metal rod called the current, ground, and potential electrodes.
Megger or insulation tester is a device used to measure very large resistors, typically up to 2 gigaherms with a test voltage of up to 5 kV, and can be used to measure the insulation resistance of cables, motors, transformers, generators and other electrical equipment. To be
Micro-ohm meter or millimeter-meter is a device used to measure electrical resistivity less than 1 ohm, which is commonly used to measure wire length, resistor of connectors, and so on. The authentic brands of Ohm meter are as follows: hioki Ohm meter, Ohm meter fluke, Ohm Unity meter, Ohm meter holdpeak, Ohm meter Benthek, Ohm meter Victor,Kyoritsu / Japan, Tess, Testo,kimo
