EL-50772  Insulation Multimeter

For regional equivalent tools, refer to Special Tools

Diagnosis for isolation loss requires insulation testing with high voltage potential. Special multimeters that utilize their own built-in high voltage, such as the EL-50772  Insulation Multimeter, test the isolation capability of high voltage components and circuits. Understanding an insulation multimeter and how it functions is necessary to obtain proper test results.
