3. Set the SVD by rotating the trackball; adjust the angle and SV size according to the
actual situation.
4. Press <PW>/<CW> again or <Update> to enter PW/CW Mode and perform the
examination. You can also adjust the SV size, angle and depth in the real-time
scanning.
5. Adjust the image parameters during PW/CW mode scanning to obtain optimized
images.
6. Perform other operations (e.g. measurement and calculation) if necessary.
„ If you choose "Enter 1D Mode Directly" in "[Setup] → [Image Preset] → [Other]", then
the sampling line will be displayed at all times in B mode images, and pressing <PW>/
<CW> will directly enter PW/ CW mode.
