B. MEASURING TOOLS
+
Select the Measurement icon
NOTE:
This is a good time to verify your calibration. Using the ANY
ANGLE TOOL, take a measurement of the same “known”
dimension you used in the Calibration step. If the measurement
is the same or very close, the calibration was successful.
C. MEASUREMENT CHOICES
1.
Any Angle Line Measurement
+
Click from one point and drag to the next point, and then release the click.
2.
Continuous Line Measurement
+
The Continuous Line measurement allows you to measure
any
continuous desired length, not just a straight line.
Simply click and drag from one point to other desired point, and then release mouse button.
3.
Radius Circle
Measurement
+
Click and drag a line out to the desired radius and release the mouse button.
+
The radius, circumference and area of the circle will show up accordingly.
4.
Diameter Circle
Measurement
+
Click and drag a line out to the desired diameter and release the mouse button.
+
The diameter, circumference and area of the circle will show up accordingly.
5.
Three Point Angle Measurement
+
Cllick any three points in an angle and the value of the angle will be displayed.
D. SET THE CALIBRATION MAGNIFICATION
+
So far the calibration and measurement features we have discussed involve the measurements on ONE image (your saved image)
and the magnifi cation rate was determined by the computer when calibrating.
+
The MicroDirect
®
Portable Capture HD software allows you to “lock in” a magnifi cation rate, which allows you to take multiple pictures
and then make measurements on them based on this “locked in” rate.
NOTE:
Once the calibration is completed, you cannot change the physical position or focus range of your microscope, or you will
change the actual magnifi cation and your measurements will not be correct.
+
Click
> Set magnifi cation > Set capture magnifi cation.
Now any pictures you take from this point forward will use the
same magnifi cation rate for your measuring. Remember, you cannot
change the position of the microscope or focus point or the
magnifi cation will be wrong and you will have to reset it.
