Multi-Function Automotive Tester RMM500

Multi-function automotive tester, designed specifically to find electrical automotive faults. The RMM500 only has settings relevant for automotive use. The innovative current test mode allows the technician to take amp readings directly at the fuse box without removing the fuses, saving time for garages. It features a voltage check, with a traffic light result indicator, giving an instant and easy-to-read assessment of the battery charge levels. The multi-function tester assesses circuit voltages, provides early indication of alternator or starter motor issues, quickly finds breaks in cables and faulty connections, can test operation of fuel injectors, check faulty sensors and more.
