Acoustic Detection |
Ultrasonic Spectrum Function |
Supports PRPD analysis graph function, supports more than three center frequencies, has PD value display, and supports phase and synchronization frequency adjustment. |
|
Threshold Adjustment |
Has threshold adjustment function. In noisy and interfering environments, the upper and lower limits of positioning imaging can be set to shield interference signals; at the same time, the imaging area can be selected, and interference outside the area will no longer be imaged. |
|
|
Signal Spectrum Distribution Graph |
Has the function of signal spectrum distribution graph, which can display the dynamic graph of the spectrum distribution of the measured signal in real time. |
|
|
Frequency Band Selection and Adjustment |
The upper and lower limits of the sound detection frequency band can be manually adjusted continuously and quickly. |
|
|
Imaging Dynamic Range Adjustment |
Has imaging dynamic range adjustment function, and the imaging threshold can be adjusted on the interface to scale the spot display size and accurately locate the fault point without entering the secondary menu. |
