Description
An ohm meter, also known as an ohmmeter, is a device used to measure electrical resistance in ohms. Resistor is an electrical property that opposes the flow of electric current through a conductor.
The ohmmeter consists of a meter and two test leads. To perform a measurement, one end of each test lead is connected to the terminals of the resistor or device to be measured. Then, the meter reading is taken.
It is important to ensure that the circuit or device is turned off before taking the measurement to prevent damage to the ohmmeter or circuit. It is also essential to note that some devices or components may have internal resistances that can affect measurements.
This V2. ESR and Low Ohm Meter have a measurement range of 0.001 to 100.0R, compatible with circuit testing. Using a 100 KHz true sine wave to measure the ESR value, which is equal to the test method of the capacitor manufacturer.
Characteristics:
The impedance becomes small, and we can measure the true value of the resistance in series.
Using this theory, we can measure that the capacitor is BAD/damaged or in good condition.
Our ESR meter only applies less than 15mV DC or peak-to-peak in a good capacitor, as a result, we can use it as a circuit test.
During the repair of TV, LCD, audio board, etc. we can test in the circuit that the capacitor is good or not.
Dual terminal, for quick and easy inspection of the capacitor’s internal resistor, a printed ESR table for quick verification.
Equipped with an SMD alligator clip for more accurate testing. Copper plating on the surface, which is anti-corrosion and rust-resistant.
