7. Operation Method
• There are two ways to use the touch sensor: one is for establishing the datum point and the other is for measuring a
workpiece without destroying the datum point.
Absolute mode (ABS)
This is a mode for establishing a datum point.
A datum point can be established or a distance from the datum point can be measured by the load/hold operation.
Incremental mode (INC)
In this mode, a datum point can not be established.
Pitch measurement of a workpiece can be performed by the load/hold operation without destroying the datum point which has
been already established.
• Depending on usage, switch the display mode between INC and ABS before starting the actual controls.
• In the following examples , the display resolution is 0.0005 mm, and the feeler ball of the touch sensor is 10 mm across.
• If a load or hold operation has been erroneously performed, press the
or hold operation again.
• Be sure to touch the machine table with the feeler ball gently. If the feeler ball touches the table roughly, the feeler ball and
the table may be damaged.

3. Maintenance
If the sensor is left unused for a long period, be sure to apply a rust-preventive. Especially, if the steel ball or shank rusts, the
accuracy will be affected.
Rust Veto Heavy by E. F. Houghton & Co. is recommended as a rust preventive oil.
