MS012 – Tester for voltage regulators



The device simulates installation of voltage regulator MS012 on faultless alternator in order to test its operating performance under different loads and modes, under various rotor resistance parameters. The handset tester conducts diagnostics of all existing types and models of voltage regulators. New types and models of voltage regulators can easily be added by updating software through USB-port. The equipment is controlled by three encoders and a sensor on colored display. Diagnostics lasts about 2 minutes.
