No need for
origin-setting
The ABS (absolute) scale requires no origin
setting after power-on and also has no limit to
response speed.
The slider provides smooth, stable and comfortable operation.
• A battery life of approximately 3.5 years has been achieved under normal use through
the adoption of Mitutoyo's ABSOLUTE scale.
• The slider configuration features an ergonomic, thumb-friendly shape.
• Step-measurement capable.
• Font height: 9mm,alleviation of fatigue with the high-contrast LCD
• Carbide-tipped jaw models are ideally suited to the measurement of rough-machined
workpieces, castings, grindstones, etc.
• The data output function allows integration into statistical process control
and measurement systems.

An inspection certificate is included
standard with each caliper.
The quality of the slider working
surface has improved with the
latest machining technology.

ABS (absolute) measurement function:
Enables absolute-mode measurement to be
started without any zero-setting after switch-on.
The absolute origin position can be set, or reset,
with the ORIGIN switch at any time.
INC (incremental) measurement function:
Enables the display value to be set to zero,
temporarily, at the current slider position to
enable easy incremental-mode measurement.
