3. BASIC OPERATIONS
Step 3 With the Cancel key, release the Hold mode of the display, and move the
machine table so the counter reads zero. Centering is now complete.
IMPORTANT
• Leave an interval of at least one second from the time the touch signal probe comes in
contact with the workpiece until the next contact. If the interval is less than one second,
it may be impossible for the counter to detect the measurement point.
• Do not displace any axis scale during numeric entry. If displaced during entry for
presetting, etc., the scale unit may be damaged due to an overrun.
• Even if the counter exceeds the counting range, Error 30 will not be displayed during
numeric entry. The error message will be displayed after numeric entry has been
completed.
• Do not displace any axis scale too much while presetting is being performed.
3) Measuring with the touch signal probe
The KA counter can be connected to a touch signal probe (optional) and can measure
the dimensions of the workpiece.
The display value is held while the touch signal probe is in contact with the workpiece.
This operation can be performed repeatedly until quitting the touch signal probe
measurement function. Press the Cancel key to quit.
• Measuring the dimensions of the workpiece in the X-axis direction
Step 1 In order to subtract the diameter of the ball tip of the touch signal probe from the
measured value, perform key operation to start counting from that value.
In the example below, the diameter of the ball tip of the touch signal probe is
taken to be 10mm.
IMPORTANT
The touch signal probe comes in contact with both ends of the workpiece, so preset the
KA counter to correct for the diameter of the probe ball tip. The sign of the corrected
value should be negative when measuring the outside diameter, and positive when
measuring the inside diameter.
Step 2 Bring the touch signal probe in contact with reference surface of the workpiece.
A buzzer sounds during contact, and when it is removed counting starts.
