Isolation Tester
A diagnostic tool for checking insulation resistance in high-voltage systems.
Isolation testers verify that high-voltage circuits are properly insulated from the vehicle chassis. They measure resistance levels to prevent electric shock and detect leakage paths. Essential for hybrid and EV safety checks, these tools ensure compliance with electrical standards. Regular insulation testing reduces risks during maintenance and repair. Always used with insulated gloves and protective equipment.
