Absolute and Incremental Presets
To maintain the best tolerance and to minimize the chance of errors, use
• absolute presets for absolute dimensions.
• incremental presets for incremental dimensions.
The following examples, shows how to make the identical part using absolute
presetting or incremental presetting.
Absolute Example:
.72
1.44
2.44 Note: When you enter an absolute preset,
it does not matter where the tool
position is. This system calculates
the desired location from absolute zero
(datum).
1. Verify the readout is in ABS mode. If not press
A
.
2. Press, in order, X key, then type in .

then E .
3. Repeat for dimensions 1.44 and 2.44.

Note: When you enter an incremental
preset, the tool must be posi-
tioned at the location you are
dimensioning from.
Incremental Example:
1. Verify the readout is in ABS mode. If not
press
A .
2. Enter the key sequence:

E .
3. Display will automatically shift to incre-
mental. Move the X-axis until “0.0000” is
displayed.
4. Enter the key sequence:

5. Move the X-axis until “0.0000” is displayed.
6. Repeat steps 4 & 5 for incremental dimen-
sion 1.00.
