OPERATION
Centerline
With MICRO-LINE , you can find the centerline (midpoint) between any
two positions on your part. You can establish centerline as your datum
by using absolute dimensions or you can create a centerline using
incremental measurements without affecting your current datum.
Refer to “Setting the Datum (Absolute Zero)” on pg. 12.
Setting the Datum on a Centerline
1. Press the ABS/INCR key until ABS is selected.
2. Move the table to the first location.
3. Press the ZERO key twice for the axis (X, Y, or Z) you want to find
the centerline for.
4. Move the table to the second location along the same axis.
5. Press the C/L (centerline) key. Dashes will flash on the screen.
6. Press the appropriate key ( X , Y , or Z ) for the axis you’re measuring.
7. MICRO-LINE will measure the distance between the two points,
then divide the sum in half. You can locate the centerline by moving
the table until the position for the axis you measured reads “0.”
Repeat the procedure to locate the midpoint for multiple axes. An
example appears on the next page.
