MS021
Tester for diagnostics of diode bridges of alternators
The tester MS021 enables the accurate evaluation of the technical condition of alternator diode bridges or diodes – separately. The tester identifies the type and specifications of diodes, reports about the failure mode and diagnoses the diode degradation.
Manufacturer:
MSG Equipment
The tester MS021 is used during the alternator repair for the diagnostics of diode bridges, and it can detect:
- diode breakdown;
- diode cut;
- diode type (common diode, avalanche diode);
- diode degradation (extreme drop of forward voltage);
- avalanche diode reverse breakdown voltage;
- bad diode connection with the bus bar.
Features:
- Testing with the alternating current for the most accurate and full evaluation of the diode technical condition;
- The tester checks any diode bridge types and diode types;
- Colour failure identification.
