Correction Function |
Windscreen correction function |
Corrects the effect on frequency characteristics when a windscreen (WS-10, WS-15, WS-16) is installed to comply with standards. |
Diffuse sound field correction function |
Correct the effect on frequency response to comply with standards in a diffuse sound field |
|
Delay Time |
After the measurement start operation, measurement will start after the specified time has elapsed (OFF, 1, 3, 5, 10 seconds) |
|
Back erase function |
When this function is implemented, data from a specified time back is excluded from the calculation (OFF, 1, 3, 5 seconds), cannot be used in conjunction with Auto store mode or waveform recording |
