2.4 Measuring the Inside Diameter
Measure the diameter (inside diameter) of a hole. By scanning the upper and lower surfaces of a hole
with the stylus, the peak points can be detected. The diameter is calculated from the The
diameter of a semicircle where part of the top or bottom of the hole is missing cannot be obtained.
This section explains the measurement procedure using the surface plate as the origin (ABS measure-
ment system).

Detect the lowest point of the hole.
• If [Auto] (automatic termination) is set, ensure that the stylus is positioned to pass through the
lowest point of the hole. When the stylus is raised about 0.5 mm from the lowest point of the hole,
a beep sound will be made, and the peak-point detection will automatically terminate.
• Bring the stylus into contact within 0.5 mm of the lowest point. Measuring with a wider range may
increase measurement errors.
1 Turn the probe unit up/down wheel, and slow-
ly bring the stylus into contact near the center
of the bottom surface of the hole until there
is a "beep" sound (keep the stylus in contact
with the surface).
