This instrument helps measure electrical insulation at specified voltages (250V, 500V, or 1000V). It is a necessary tool for assessing the integrity of an electrical circuit, particularly to ensure that the components and installation in electric vehicles are completely isolated from the chassis.

In industrial facilities, it is the tool that allows for the periodic inspection of insulation resistance. Measurements are required by the regulation DIN VDE 0105-100 (VDE 0105-100):2009-10. It is particularly recommended for use in electric and hybrid vehicles.
