d) Press
: The instrument works in B/M mode. The left side is in B mode and the right side is
in M mode. The sampling line is in the center of the image in B mode and it will move left or right by
pressing
or
(This mode is effective only when it is in the magnification of 1.0).
e) Press
: The instrument works in M mode.
Note: this function only works for 3.5MHz convex array probe in M mode.
5.4 Image Magnification Selection
When 3.5MHz convex array probe in the real time under B mode, press
may choose zoom
ratio include ×0.8, ×1.0, ×1.2, ×1.5, ×1.8, × 2.0 six patterns; Press this key once, the instrument will
circulate to the next zoom ratio.
When 6.5MHz dimpling array probe or 7.5MHz linear array probe works, press
may choose
zoom ratio include ×0.8, ×1.0, and × 1.2, × 1.5 four patterns.
