TDMS files are required for analysis of symptoms correctly.

When saving the TDMS file, please set the gain to +20dB and the image range

to 0.5dB, create a noise source by playing music on your mobile phone, etc. to

check the results, and send the file to us. We will analyze the results and

provide you with further instructions.

If you get an error while updating F/W, it's usually due to a static IP setting.

Please try to reset the static IP as shown below and then try to update F/W again. 

You can also check this in the manual.

If the image is blurred, first make sure that the lens is free of dust, fingerprints, scratches. If possible, clean or if damaged, contact us for the replacement of the lens. If the lens is clean and free of scratches, the optical camera may be out of focus. Then, rotate the optical camera to change the camera's focus until the image is correctly displayed and focused. Remember that after changing the focus of the optical camera, the real-time software should perform image calibration again.

When you use the sound camera in record mode, the real-time software saves the recording file in TDMS format. This file can be opened with real-time software and post-processing software or NI Lab View. TDMS means Technical Data Management Streaming, which is the format developed by National Instruments to store measurement data. You can save it in AVI format if you want to play it as a regular video later. This requires you to change the real-time software mode to play mode so that the color changes to blue(play mode) by clicking the orange button(record mode) in the upper left corner. The fourth button, "Open Data File," should then be used to open the corresponding TDMS file. Press the button on the right side of the "Open Date File" to save the data in AVI format to a default folder.

If a bias error occurs in the visualization of the beamforming map, i.e. if the position of the beamforming map and the noise source are not aligned, the image must be calibrated. For image calibration, you can use 4 kHz of sound waves or other sound waves within the recommended range of 2 to 10 kHz. You can manually find the center of the beamforming map to fit the position of the actual noise source, or use the automatic calibration button. For automatic calibration, first press the Auto Calibration button and drag the center of the beamforming map directly to the center of the noise source. For manual calibration, change the x and y values to match the correct position of the noise source.
