of the pink noise is too high or too low, [Vol. UP] or [Vol. DOWN]
will appear on the display. If this happens, adjust the volume
until the display disappears.

easier, slight errors may occur in the measurement data under
some circumstances when this function is used. In addition, it is
not equivalent to the precise measurements that can be made by
specialist measuring devices.
