Insulation resistance is the most basic insulation index for electrical equipment and electrical lines. For the handover test of low-voltage electrical installations, the insulation resistance of motors, distribution equipment and distribution lines at room temperature should not be less than 0.5MΩ (for equipment and lines in operation, the insulation resistance should not be less than 1MΩ/kV). Low-voltage appliances and their connecting cables and the insulation resistance of the secondary circuit should not be less than 1MΩ in general; in the more humid environment should not be less than 0.5MΩ; the insulation resistance of the secondary circuit of the small busbar should not be less than 10MΩ. Class I hand-held power tools insulation resistance should not be less than 2MΩ. Insulation Resistance: add DC voltage to the dielectric, after a certain period of time after the end of the process of polarization, the leakage current flowing through the dielectric The corresponding resistance is called insulation resistance. It is an intelligent measuring instrument that can quickly measure the insulation performance of electronic components, dielectric materials, equipment and wires and cables. Adopting large-size liquid crystal, humanized menu layout, so that the user can operate the instrument more conveniently. The test steps can be programmed by the user, up to 18 steps. For example, user programmable charging, waiting, testing, discharging, etc., each step can last up to 100 s. Standardly equipped with RS232, USB DEVICE, Handler and other interfaces. Among them, Handler interface provides convenience for realizing automatic test system. Scanning port, for a large number of components to provide a convenient test. Users can also be equipped with a scanner to speed up component testing.
