2.1 COORDINATE
(1) Incremental/Absolute coordinate
Absolute coor
dinate is the basic coordinate.
Incr
emental coordinate is coordinate which is relative to the absolute coordinate.
(2) Polar/Cartesian coordinate
Car
tesian coordinate expresses a point with (x, y).
Polar coor
dinate expresses a point with (ρ, θ).
Example: " Current Position" is displayed in the message window
X window displays 1.000
Y window displays 2.125
Indicates that the current position is (1.000, 2.125) in Cartesian coordinate,
and it is (2.349, 64.799) in polar coordinate.
Note:
(1) The italics with '____'indicate that it is a terminology, the same as following.
2.2 EDGE/CROSSHAIR MODE, AUTO/MANUAL MODE
In Crosshairs mode, the display values of X window and Y window are updated
continuously, yet in Edge
mode, they are update only when the Optical Edge Detector
are moving from dark area to light area or from light to dark. If WDC-300 is in the Edge
mode and AUTO mode at the same time, sample points will be probed automatically
and user needn't put the ENTER key; otherwise, the Enter key must be pressed to catch
sample point.
2.3 MEASUREMENT MODE
WDC-300 has two Measurement Modes: Forward Annotation Measurement and
Backward Annotation Measurement. The Forward Annotation Measurement means that
the number (less than 50) of sample points are preset before measuring, . In Backward
Annotation Measurement, it is not necessary for operator to setup the number of
sample points, the number of points is decided during the measuring. You can set the
measurement mode at interior setting.
2.4 SAVING FEATURES
Graphical feature is stored by two ways: temporary storing and permanent storing. The
temporary features will be lost when power is off, however the permanent features will
be kept for ever. So the permanent feature is used to save some used usually and
important features.
WDC-300 can store ten temporary features from a0 to a9 and one hundred permanent
features from 00 to 99. The current feature will be temporary feature a0 after
measurement is finished, and the last a0 will be changed into a1, and the rest
temporary features will does the same way. The last a9 will be lost. The temporary
feature can be changed into the permanent feature by store operation and the
permanent feature also can be recalled as temporary feature a0.
Manual WDC-300 9
2. TERMINOLOGY
2.5 USER PROGRAM
WDC-300 provides user program. User can create his own program, which makes
measurement very quickly and conveniently.
Adopting E2PROM, WDC-300 has a capacity of 10 user programs which No is from 0 to
9. Each user program can contain 100 steps from 0 to 99, and one user program can
invoke another user program, the invoked layers are utmost 10 layers.
2.6 INPUTTING VALUE
Press ENTER to confirm after inputting value. Press QUIT to give up value and quit. Press
the CANCEL to cancel the last inputted key, and you can also press ENTER at the
beginning to enter the preset value which is shown on the message window.
2.7 C
OORDINATE SKEWING
In order to improve measurement precision and make the measurement conveniently,
WDC-300 provides coordinate skew function, which help user skew work-piece.
When work-piece's shape is irregular or there is an angle between work-piece's edge
and X axis or Y axis, WDC-300 skew X-axis or Y-axis to the edge of work-piece to
improve measurement precision and the measurement convenience.
2.8 STORING PARAMETERS WHEN POWER FAILS
WDC-300 can store parameters when power fails. It can restore the failure state if the
power is supplied again.
Note:
(1) Temporary feature will be lost automatically if power failed.
(2) Linear scale cannot be moved after power fails.
2.9 MEASURE EASY
WDC-300 provides a function-Measure Easy. When the Measure Easy is open, the
system can create a feature only inputting some points. Of course, some rules should
be remember:
1. Input only one point, and then press "Finish" if you want to measure a point.
2. Input two points and then press "finish", you will get a line feature.
3. If you input three or more than three points, system would calculating that the
graphics is a circle or a line.
4. Measure Easy could not be used to measure distance feature and angle feature.
2.10 PRESETTING, MEASURING AND CONSTRUCTING FEATURES
WDC-300 provides 3 methods ---- preset/ construct/measure to obtain a new graphical
feature.
Preset: Users input value from panel, then WDC-300 gets message of feature.
Measure: WDC-300 get message of feature after it deals with the data get form
scale. .
Construct: User uses existent features to construct a new feature (including
temporary feature and permanent feature).
10 Manual WDC-300
2.11 SHOWING FEATURE'S MESSAGE
Graphical features' message can be viewed in different ways from Cartesian coordinate
and polar coordinate
1. Point feature
(1) In Cartesian coordinate, the point feature is displayed with X offset value and Y |
offset value from datum point.
Example: " a0 Point X/Y " is displayed in the message window
1.000 is displayed in the X window
1.000 is displayed in the Y window
It indicates a0 is a point, its coordinate data is (1.000, 1.000) in cartesian,
and it can be changed into (1.414, 45.000) in polar.
(2) In polar coordinate, the point feature data is displayed by the distance from the
point to the datum point and the angle between positive direction of X axis and the
line from datum point to the sampled point.
Example: " a1 Point r/a" is displayed in the message window
1.414 is displayed in the X window
45.000 is displayed in the Y window
It indicates a1 is a point feature, its coordinate is (1.414, 45.000) in polar,
and it will be changed into (1.000, 1.000) in cartesian coordinate.
2. Line feature
The line feature will be displayed with it's one point element which is nearest from
datum point and the angle between the line and positive direction of X axis.
Example: " a1 line X/Y " is displayed in the message window
1.000 is displayed in the X window
-1.000 is displayed in the Y window
It indicates a1 is a line, the cartesian coordinate of the point is (1.000, -1.000) which
is nearest from datum. It will be changed into (1.414, 315.000) in polar.
Press MORE," <… " is displayed in the message window
45.000 is displayed in the X window
It indicates the angle between this line and x axis' positive direction is 45.000°.
3. Circle feature
A circle feature consists of its central point and its radius.
Example: "00 circle X/Y" is displayed in the message window
1.000 is displayed in the X window
1.000 is displayed in the Y window
It indicates the first permanent feature is a circle, the center of the circle
(1.000, 1.000) in Cartesian coordinate, and it will be changed into (1.414, 45.000) in
Polar coordinate.
Press MORE, " r/d…" is displayed in the message window
2.000 is displayed in the X window
4.000 is displayed in the Y window
It indicates the radius of the circle is 2.000 and the diameter is 4.000.
4. Distance feature
The distance feature is the offset values of X axis and Y axis between two point
features.
Example: " 00 offset X/Y " is displayed in the message window
1.000 is displayed in the X window
1.000 is displayed in the Y window
It indicates that the first permanent feature is a distance feature, the offset value of
X is 1.000, and the offset value of Y is 1.000.
Press the MORE, " Distance " is displayed in the message window
1.414 is displayed in the X window
It indicates the distance between two points is 1.414.
Manual WDC-300 11
5. Angle feature
Angle feature is an angle between two lines.
Example: " 02 Angle <12 " is displayed in the message window
45.000 is displayed in the X window
315.000 is displayed in the Y window
It indicates the first permanent feature is an angle feature, and its value is 45°.
Press MORE, " <34…" is displayed in the message window
135.000 is displayed in the X window
225.000 is displayed in the Y window.
