When the generator is running, it can detect the impact and vibration due to the defect and failure of bearing, gear, valve, crank, cylinder, gear box, and vehicle body…etc. With this equipment, the repairer can clearly locate which part of the machine cause the noise and how serious is it; even though the repairer operates the equipment in a very noisy environment.
