1. DESCRIPTION
Tester MSG MS012 COM is used for diagnostics of voltage regulators. It simulates installation of
voltage regulator on faultless alternator in order to test its operation under different loads and
modes, under various rotor resistance parameters.
The tester demonstrates how a voltage regulator will operate on the alternator with a certain rotor
resistance. The tester detects if it is possible to install a voltage regulator on the alternator.
A voltage regulator is tested under load, as on the real alternator.
MS012 COM Tester contains the possibility to test all existing types/models of voltage regulators.
New types/models of voltage regulators can easily be added by updating software through USB-
port.
Operation of the tester is conducted by three encoders and a sensor on colored 4.3” TFT display.
MS012 COM Tester is easy and user-friendly in operation. Total testing of a voltage regulator lasts
no longer than 1-2 minutes.

• EL LOAD: the adjustment knob with two functions: required resistance of simulated rotor can
be set in the main menu, in voltage regulator testing mode (12V/24V), the load on the simulated
alternator and on a tested voltage regulator, respectively, can be changed from 0% to 100%.
• STATOR: the adjustment knob to change frequency of stator winding from 0 to 6000 in voltage
regulator testing mode (12V/24V). The frequency appear on the display as car engine rotation
frequency.
• VOLTAGE: the adjustment knob to set required current voltage generated by a voltage
regulator in voltage regulator testing mode (12V/24V). Used with terminal modes: COM (LIN,
BSS); RLO; C; SIG; P-D.
