(7). Press
ENTER
, system return "Point Pts 03" menu.
(8). It is same to setup the number of points to get a circle feature or a line feature.
(9). Press
FINISH
or
QUIT
twice to exit setup state, then return normal
monitor state.

KEW ALIGNMENT
Usually, we take it for granted that the workpiece is aligned on X axis or Y axis. An
improper aligned or "mis-skewed" workpiece will result in inaccurate measurement. It is
a better choice to use skew function when user start to measure a new workpiece.
User probes 2 - 50 points on the selected edge , then WDC-300 changes the display
coordinate automatically. The selected edge become X axis or Y axis in new coordinate.
steps:
(1). Press
SKEW
, then "Probe Line" is displayed and the light flashed.
(2). Probe three points at an edge. The sample point would be probed automatically
in auto mode and by pressing
ENTER
in manual mode.
(3). Repeat the above steps to probe enough points. Press
FINISH
when enough
points are sampled in forward annotation mode. User need not do press
FINISH
in backward annotation, then "X (or Y) Axis Skewed" is displayed , when
the light is on but not flash. WDC-300 outputs display value in new coordinate
through complex calculation.
(4) Press
POINT
to determine a right point on the line as datum point. Press
ENTER
when you select the point. If you probe enough points (you should press
FINISH
after all points are probed), the system would determine the suitable point. Then
"a0 Point X/Y" is displayed, which means coordinate value of this point is
displayed on the X screen and Y screen. Press
more
to get more message.
(5). Press
ORG
to set new datum point. The light would be on and "Select Point" is
displayed. Then the feature probed last is displayed. (If there is no graphics,
"No Feat Selected" is displayed and then quit from system). Press
or to
select a point or center of a circle or vertex of an angle .
(6). Press
ENTER
to determine the selected feature and then the new datum point is
set.
Note:
1
If you want to exit the skew state, please keep pressing the SKEW key for about 3 second.
2
If you want to see the previous coordinate that had not been skewed, just press the
SKEW key again. And press the SKEW key again, the WDC-300 will go back to the SKEW state.

EASURING A CIRCLE
You can probe a minimum of 3 points and a maximum of 50 points when you measure
a circle, the points is on the circle or around accordingly. And if you want to measure a
circle preciously, you should probe at least 3 points, also the points is better to distribute
uniformity on the circle. You can determine the number of points to be probed in
backward annotation. When you measure the circle in forward annotation mode, the
required number points will be displayed on LED windows. If you probe more then 3
points the system will calculate the circle with a most suitable arithmetic. The following
will show you how to measure a circle in the forward annotation mode.
