Accurate, yet Affordable,
DRO System from Mitutoyo
Mitutoyo's Linear Scale System tightly couples linear scale units with dedicated Digital Readout (DRO) units to offer
accurate detection and display of axial displacement for machine tools and measuring equipment. The Linear Scale
System can be configured to best meet your specific application, whether it be machining or measuring, just by
choosing a suitable combination of scale unit and display unit. Scale units have many measuring length ranges and
the display units feature remote zero setting, switchable resolution and multipurpose one-touch macro keys. The
Linear Scale System has superior ease-of-use and is reliable, both of which are features that can dramatically improve
machining accuracy and efficiency.

Ultra Precision Manufacture 11 Meters
Underground
Mitutoyo Kiyohara Plant, which is a factory exclusively for the
production of Linear Scales and other precision scales, has a complete
system for producing master scales to be used in finished products,
such as CMMs, vision measuring systems, profile projectors, and
measuring microscopes. To improve the accuracy of scales and
quality control technologies, the integral laboratory at the Kiyohara
Plant was constructed eleven meters underground. It provides

precision manufacture and evaluation of scales. Its unique design
and construction isolates the laboratory from external vibrations and
ensures minimal variations in temperature and humidity.

Note) When selecting the size of a scale unit for your application, make sure that the maximum travel range of the scale unit (L

) is larger than the maximum travel range
of the machine. Also, take into consideration in selecting a size that the accuracy of the scale unit is guaranteed only within the range of the effective measuring
length (L
0
).

The assembly-type Linear Scale®uses a highly accurate glass scale
GRATING¬PITCH¬OF¬ ¬«M¬AS¬THE¬BASIC¬STANDARD¬OF¬LENGTH¬4HE¬GRATING¬
is irradiated with parallel light generated with a Light-Emitting Diode
(LED) and collimator lens. The parallel light transmitted through the
grating generates an interference pattern with the same pitch as that
of a grating on the photodiode array of the light-receiving device.
The receiver output signal is 2-phase sinusoidal with a wavelength

is electrically converted to 2-phase square-wave signals by the
interpolation circuit. The much smaller working resolution is achieved
by detecting the cyclic variation in light intensity incident on the
receiver array, as the scale is displaced in a measuring direction, and
interpolating accordingly to output a corresponding displacement
value.

SPECIAL FUNCTIONS
Expansion/contraction
coefficient setting
This function multiplies the actual counter
measurements by a constant factor. This is useful in, for
example, mold manufacture by allowing the mold to be
machined to the actual molded component dimensions
directly, without having to increase the machining
dimensions manually to allow for material shrinkage
after molding. Tedious work can thus be reduced and
the risk of mistakes in calculation eliminated.
Memory backup
The backup battery ensures the most recent display
value is retained even when the counter is off.
Lower digit blanking out
Unnecessary lower digits (up to 9 digits of the lowest
digits) can be blanked out.
Absolute/incremental
coordinate system switching
For each axis, the measured value can be obtained in
EITHER¬ABSOLUTE¬!"3¬OR¬INCREMENTAL¬).# ¬COORDINATES¬
This function is useful, for example, if the following
operation is performed. Set the datum point for a
workpiece in the absolute mode. Then, after performing
zero setting, presetting, etc., in the incremental mode,
return to the absolute mode. In this way the absolute
distance from the datum point can be easily displayed.
1/2 calculation
This function halves the display value.

depending on the model.)
Measurement direction

The measurement direction can be selected.
Resolution setting
The most suitable resolution can be selected to meet
measuring applications. Available resolutions depend
upon the counter to be used.
Preset
This function allows the user to enter a numeric value
on the counter display. Any preset value can be retrieved
whenever necessary.

Linearity error compensation
Machine errors caused due to workpiece weight,
inaccurate table adjustment, etc., are linearly
compensated to reduce the positioning error.

intervals. Since the counter keeps the total displacement
in absolute coordinates, a positioning error made by the
operator at one tooling position has no effect on the
remaining positions.
Diameter display
The doubled scale displacement can be displayed. This
convenient function can be used to display the diameter
of a workpiece during a turning operation.
Bolt-hole circle machining
In milling, the drilling positions along the circumference
of the base circle in the absolute zero approach
mode can be easily displayed by entering the center
coordinates, diameter, and number of divisions of the
base circle.
Touch-signal probe
The optional touch-signal probe makes it easy to
perform such operations as datum point setting
(detecting the workpiece edge and setting the counter
display to zero), workpiece centering, and dimensional
measurement (detecting the workpiece end point and
holding the counter display).
Memorization of machining
reference point for each
cutting tool (for KA counter)
Absolute coordinate and incremental coordinate can be
switched by every one of four cutting tools. The counter
can memorize the center of a machining workpiece as
a reference point and it can display the diameter of the
machine workpiece by using absolute coordinate. The
counter can zeroset/preset at the arbitrary position by
using incremental coordinate.
Scale reference point setting
4HE¬LINEAR¬SCALE¬HAS¬SCALE¬REFERENCE¬POINTS¬AT¬MM¬
intervals. When one of the points is detected, the linear
scale issues a signal to hold/restart counting. If the
distance from a scale reference point to the machine
origin is registered as the offset value, it will be retained
even when the power is off (hold function). When the
power is turned on, the machine origin or machining
datum can be easily recalled (set function).
Addition of 2-scale data
The sum of the displayed values of two axes can be
displayed. If a machine has two feed components, fine
feed and coarse feed, each with its own scale, this
function can be used to sum the two feed values.
