General Measurement 3-9
3.3 M General Measurements
3.3.1 Distance
Function: Measures the distance between two points on the M Mode image.
1. Click [Distance] in the measurement menu, and two dotted lines perpendicular to each other
appear on the screen.
2. Move the crossing point of the dotted lines to the measurement starting point and press <Set>.
3. Move the crossing point to the end point, and then the crossing point can only be moved in
vertical direction. Here,
Press <Update> to switch between the fixed end and active end of the caliper. Or,
Press <Clear> to cancel setting the starting point.
4. Press <Set> to set the end point.
3.3.2 Time
Function: Measures the time interval between two points on the M Mode image.
1. Click [Time] in the measurement menu, and two dotted lines perpendicular to each other
appear on the screen.
2. Move the crossing point of the dotted lines to the measurement starting point and press <Set>.
3. Move the crossing point to the measurement end point. The crossing point can only be moved
in the horizontal direction. Here,
Press <Update> to switch between the fixed end and active end of the caliper. Or,
Press <Clear> to cancel setting the starting point.
4. Press <Set> to set the end point.
3.3.3 Slope
Function: Measures the distance and time between two points on the M Mode image and
calculates the slope between the two points.
1. Click [Slope] in the measurement menu, and two dotted lines perpendicular to each other
appear on the screen.
2. Move the crossing point of the dotted lines to the measurement starting point and press <Set>.
3. Move the crossing point to the measurement end point. The cross point is connected to the
starting point by a dashed line. Here,
Press <Update> to switch between the fixed end and active end of the caliper. Or,
Press <Clear> to cancel setting the starting point.
4. Press <Set> to set the end point.
3.3.4 Velocity
Function: Measures the distance and time between two points on the M Mode image and then
calculates the average velocity between the two points.
1. Click [Velocity] in the measurement menu, and two dotted lines perpendicular to each other
appear on the screen.
2. Move the crossing point of the dotted lines to the measurement starting point and press <Set>.
3. Move the crossing point to the end point, and then the crossing point can only be moved in
vertical direction.
