Overview

Q96-MΩ Q72-MΩ Q96-ZMΩ Q72-ZMΩ Isolation Meter is a measuring instrument commonly used by electricians. It is widely used to measure the insulation resistance of generators, motors, power transformers, wiring, electrical appliances and other electrical devices (such as cables for control, signal, communication and power supply). It is mainly used to check the insulation resistance of electrical equipment, household appliances or electrical lines to the ground and between phases, so as to ensure that these equipment, appliances and lines work in a normal state and avoid accidents such as electric shock casualties and equipment damage. Megger is mostly powered by hand generator, so it is also called megger. Its scale is in megaohms (m Ω).

Working principle of Q96-MΩ Q72-MΩ Q96-ZMΩ Q72-ZMΩ Isolation Meter

Under the set aging environment, the user applies a voltage of the positive and negative electrodes of the power supply to the positive and negative electrodes of the tested sample, Through a process of continuously measuring the change of insulation resistance after product test within a certain period of time (we can know the difference caused by test since the initial stage of test and the disorder of resistance value in case of failure from the change of resistance value), so as to evaluate the reliability of products. 
 the test principle of insulation resistance is to apply a constant DC voltage to the tested object, then measure the current flowing in the tested object, convert the insulation resistance value according to Ohm's law, connect each tested sample to the test circuit by multi-channel switch, add test voltage to the tested sample after a certain time, and then measure with Isolation Meter

Feature of Q96-MΩ Q72-MΩ Q96-ZMΩ Q72-ZMΩ Isolation Meter

1. The device can be self calibrated without submitting for inspection (tracing the source with class II standard resistance and digital voltmeter).

2. After self inspection, the device is equivalent to a zero error calibration, and there is no unqualified problem.

3. The voltage output of the device has automatic protection function, which will not damage the equipment even if there is a short circuit. At the same time, it also has shielding grounding and power leakage prevention functions, and the data is reliable.
