sound analyze
1.The average sensitivity from 1500Hz to 5000Hz is -151.50dB,the max value is-147.43dB,the min value is 153.40dB,with a±3dB fluctuation,while the theoretical value is-151dB.The results of the experiment prove that both the model of the extended hydrophone sensing sound signal and the theoretical analyze based on the model are right.
3.The instrument can detect all kinds of steam, diesel engine start-up performance, high-voltage ignition performance, fuel injection performance, rechargeable performance, dynamic performance, service gas phase, abnormal sound engine vibration analysis more than 30 kinds of technical parameters, and analyze the causes for the failure , the detection process, may at any time and waveform display various technical parameters and results can be random print, the machines are more than 100 kinds of domestic and foreign memory engine technical parameters, it is rich in content and the test results can be readily compared.
