SERIES 293 – ABSOLUTE Digimatic High-Accuracy Micrometer
B
•A world-leading 0.1 μm resolution makes this
micrometer ideal for customers who need to
make highly accurate measurements with a hand held tool.
•The High-Accuracy Digimatic Micrometer utilizes
Mitutoyo’s innovative 0.1 μm resolution ABS
(absolute) rotary sensor*1 and high-accuracy
screw machining technology to reduce the
instrumental error to ±0.5 μm, delivering higher
accuracy without sacrificing operability.
*1 Patent pending in Japan, the United States of America, the European
Union, and China.
•A highly rigid frame and high-performance
constant-force mechanism*2 enable more stable
measurement, while the clicks emitted while the
workpiece is being measured assure the operator
that measurement is proceeding normally.
•Transfer of body heat to the instrument is
reduced by a (removable) heat shield, minimizing
error caused by thermal expansion of the frame
when performing handheld measurements.
•The ABS sensor also eliminates the need to
perform origin setting each time the power is
turned on, letting you start measuring straight
away. With no possibility of overspeed errors,
this micrometer also delivers a higher level of
reliability.
•A range of features enables flexible
measurement, including switchable resolution
(0.0001/0.0005 mm), function lock and
preset.
*2 Patent pending in Japan, the United States of America, the European
Union, and China.

Lithium battery (CR2032) x 1
Approx. two years when used under normal conditions
Functions
Preset (ABS measurement system):
The measurement origin can be preset to any value within the
display range for convenience in measuring.
Zero-setting (INC measurement system):
The display can be zeroed at any position of the spindle,
making comparison measurement easier. Returning to the
absolute-measurement mode is easily accomplished.
Hold:
Pressing the HOLD button freezes the current value in the
display. This function is useful for preserving a measurement
in situations of poor visibility when the instrument must be
moved away from the workpiece before the reading can be
recorded.
Resolution switching:
The resolution of the display can be switched. If 0.1 μm
measurement is not required, the resolution can be switched
to 0.5 μm.
Function lock:
Functions such as preset or zero-set can be locked to avoid
inadvertently changing the origin position.
On/off:
The power can be turned off after measurement is complete.
Even after the power is turned off, the origin or last zero-set
position remains in the memory.
Auto power off:
Even if the power is left on, the power turns off automatically
if the micrometer is not used within a 20-minute period.
Measurement data output:
Measurement data can be output, allowing easy incorporation
of this instrument into a statistical process control or
measurement system.
Error alarm:
In the unlikely event of a display overflow or calculation
error, an error message is displayed and measurement stops.
Measurement cannot continue until the error is corrected.
Also, if the battery voltage drops below a certain point, the
battery indicator will turn on before measurement becomes
impossible, warning the user that the battery needs to be
replaced.

•Advanced pioneering technology has created
the next generation of micrometer, the most
revolutionary advance in micrometer technology
since James Watt invented the instrument.
•Faster measurement is achieved by using a
coarser thread which feeds the spindle by 2 mm
per revolution of the thimble. This increase in
thread lead has been made possible thanks to
new high precision thread-cutting and testing
techniques.

Patented ratchet thimble mechanism*
The patented ratchet thimble mechanism helps
ensure repeatable results by transmitting microvibrations along the spindle to the contact face
to provide a constant measuring force and
encourage good contact with the workpiece. The
ratchet works from the thimble as well as the
speeder so it is always easy to use – even when
making measurements one handed. The sound
of the ratchet provides the user with a sense of
confidence and the speeder enables the rapid
spindle feed needed when measuring widely
different dimensions.

Origin point setting (ABS measurement system):
Resets the ABS origin at the current spindle position to the
minimum value of the measuring range and switches to ABS
mode.
Zero setting (INC measurement system):
A brief press on the ZERO/ABS button sets display to zero at
the current spindle position and switches to the incremental
(INC) measuring mode. A longer press resets to the ABS
measuring mode.
Hold:
Pressing the HOLD button freezes the current value in the
display. This function is useful for preserving a measurement
in situations of poor visibility where the instrument must be
moved away from the workpiece before the reading can be
recorded.
Function lock:
This function allows the ORIGIN (origin point setting) function
and the ZERO (zero-setting ) function to be locked to prevent
these points being reset accidentally.
Auto power ON/OFF:
The reading on the LCD disappears after this instrument is
idle for about 20 minutes, but the reading and measurement
mode are retained. Turning the spindle causes the reading to
reappear.
Data output:
Models equipped with this function have an output port for
transferring measurement data to a Statistical Process Control
(SPC) system.
Error alarm:
In the unlikely event of a display overflow or calculation
error, an error message is displayed and measurement stops.
Measurement cannot continue until the error is corrected.
Also, if the battery voltage drops below a certain point, the
battery indicator will turn on before measurement becomes
impossible, warning the user that the battery needs to be
replaced.
* Excluding quantizing error.

DIMENSIONS
Measuring force is generated by the action of trapping a workpiece between the spindle face and the anvil.
The constant-force unit applies the specified measuring force.
When the preset measuring force is reached, the value on the LCD is automatically held and the hold symbol appears.
(To cancel the hold, reverse the thimble more than 1/10 revolution and press the hold button.)

•More accurate in one-handed operation:
inexperienced operators measure significantly
more accurately with this micrometer.
•Heat-insulated frame.
•Ratchet function works both from the thimble
and the speeder.
•Rotating the thimble/speeder
when the workpiece is between
the anvil and spindle causes the
ratchet mechanism to operate
and apply a constant measuring
force to the workpiece.
•Clearly audible ratchet operation for reassurance
that measurement is being performed at
constant, preset force.
•The speeder is always available for quick rotation
of spindle.
•A simple mechanism, which requires neither parts
maintenance nor special technique, is employed
in the constant-force device.
•Measuring faces: Carbide

Origin point setting (ABS measurement system):
Resets the ABS origin at the current spindle position to the
minimum value of the measuring range and switches to ABS
mode.
Zero setting (INC measurement system):
A brief press on the ZERO/ABS button sets display to zero at
the current spindle position and switches to the incremental
(INC) measuring mode. A longer press resets to the ABS
measuring mode.
Hold:
Pressing the HOLD button freezes the current value in the
display. This function is useful for preserving a measurement
in situations of poor visibility where the instrument must be
moved away from the workpiece before the reading can be
recorded.
Auto power ON/OFF:
The reading on the LCD disappears after this instrument is
idle for about 20 minutes, but the reading and measurement
mode are retained. Turning the spindle causes the reading to
reappear.
Data output:
Models equipped with this function have an output port for
transferring measurement data to a Statistical Process Control
(SPC) system.
Error alarm:
In the unlikely event of a display overflow or calculation
error, an error message is displayed and measurement stops.
Measurement cannot continue until the error is corrected.
Also, if the battery voltage drops below a certain point, the
battery indicator will turn on before measurement becomes
impossible, warning the user that the battery needs to be
replaced.

Functions
Origin point setting (ABS measurement system):
Resets the ABS origin at the current spindle position to the
minimum value of the measuring range and switches to ABS
mode.
Zero setting (INC measurement system):
A brief press on the ZERO/ABS button sets display to zero at
the current spindle position and switches to the incremental
(INC) measuring mode. A longer press resets to the ABS
measuring mode.
Hold:
Pressing the HOLD button freezes the current value in the
display. This function is useful for preserving a measurement
in situations of poor visibility where the instrument must be
moved away from the workpiece before the reading can be
recorded.
Auto power ON/OFF:
The reading on the LCD disappears after this instrument is
idle for about 20 minutes, but the reading and measurement
mode are retained. Turning the spindle causes the reading to
reappear.
Data output:
Models equipped with this function have an output port for
transferring measurement data to a Statistical Process Control
(SPC) system.
Error alarm:
In the unlikely event of a display overflow or calculation
error, an error message is displayed and measurement stops.
Measurement cannot continue until the error is corrected.
Also, if the battery voltage drops below a certain point, the
battery indicator will turn on before measurement becomes
impossible, warning the user that the battery needs to be
replaced.

■ Effect of Changing Support Method and
Orientation (Unit: µm)
Changing the support method and/or orientation of a micrometer after zero
setting affects subsequent measuring results. The tables below highlight the
measurement errors to be expected in three other cases after micrometers are zeroset in the ‘Supported at the bottom and centre' case. These actual results show
that it is best to set and measure using the same orientation and support method.

The above graph shows micrometer frame expansion due to heat transfer
from hand to frame when the frame is held in the bare hand which, as can
be seen, may result in a significant measurement error due to temperatureinduced expansion. If the micrometer must be held by hand during
measurement then try to minimize contact time. A heat insulator will reduce
this effect considerably if fitted, or gloves may be worn. (Note that the above
graph shows typical effects, and is not guaranteed).

The above experimental graph shows how a particular micrometer standard
expanded with time as people whose hand temperatures were different
(as shown) held the end of it at a room temperature of 20°C. This graph
shows that it is important not to set a micrometer while directly holding the
micrometer setting standard but to make adjustments only while wearing
gloves or lightly supporting the standard by its heat insulators.
When performing a measurement, note also that it takes time until the
expanded standard returns to the original length.
(Note that the graph values are not guaranteed values but experimental values.)

Abbe’s principle states that “maximum accuracy
is obtained when the scale and the measurement
axes are common”.
This is because any variation in the relative
angle ( ) of the moving measuring jaw on an
instrument, such as a caliper jaw micrometer,
causes displacement that is not measured
on the instrument’s scale and this is an Abbe error ( = - L in the
diagram). Spindle straightness error, play in the spindle guide or
variation of measuring force can all cause to vary and the error
increases with R.

Nominal length (mm)
In the above experiment, after the micrometer and its standard were left at a room
temperature of 20ºC for about 24 hours for temperature stabilization, the start
point was adjusted using the micrometer standard. Then, the micrometer with
its standard were left at the temperatures of 0ºC and 10ºC for about the same
period of time, and the start point was tested for shift. The above graph shows
the results for each of the sizes from 125 through 525 mm at each temperature.
This graph shows that both the micrometer and its standard must be left at the
same location for at least several hours before adjusting the start point. (Note that
the graph values are not guaranteed values but experimental values.)

■ Testing Parallelism of Micrometer Measuring
Faces
Optical parallel reading direction on the spindle side
B
■ General Notes on using the Micrometer
1. Carefully check the type, measuring range, accuracy, and other
specifications to select the appropriate model for your application.
2. Leave the micrometer and workpiece at room temperature long enough for
their temperatures to equalize before making a measurement.
3. Look directly at the index line when taking a reading against the thimble
graduations.
If the graduation lines are viewed from an angle, the correct alignment
position of the lines cannot be read due to parallax error.
Optical parallel
(b)
Fringes on the spindle side
Parallelism can be estimated using an optical parallel held between the faces.
Firstly, wring the parallel to the anvil measuring face. Then close the spindle
on the parallel using normal measuring force and count the number of red
interference fringes seen on the measuring face of the spindle in white light.
Each fringe represents a half wavelength difference in height (0.32 μm for red
fringes).
In the above figure a parallelism of approximately 1 µm is obtained from
0.32 µm x 3=0.96 µm.

■ Testing Flatness of Micrometer Measuring Faces

white light. Each fringe represents a half wavelength difference in height
(0.32 μm for red).

B-79
5. Wipe away any dust, chips and other debris from the circumference and
measuring face of the spindle as part of daily maintenance. In addition,
wipe off any stains and fingerprints on each part with dry cloth.
6. Use the constant-force device correctly so that measurements are
performed with a consistent measuring force.
7. When mounting a micrometer in a micrometer stand, the stand should
clamp the centre of the micrometer frame. Do not clamp it too tightly.
B
8. Be careful not to drop or bump the micrometer on anything. Do not rotate
the micrometer thimble using excessive force. If you believe a micrometer
may have been damaged due to accidental mishandling, ensure that it is
inspected for accuracy before further use.
9. After a long storage period or when there is no protective oil film visible,
lightly apply anti-corrosion oil to the micrometer by wiping with a cloth
soaked in it.
10. Notes on storage:
Avoid storing the micrometer in direct sunlight.
Store the micrometer in a ventilated place with low humidity.
Store the micrometer in a place with little dust.
Store the micrometer in a case or other container, which should not be
kept on the floor.
When storing the micrometer, always leave a gap of 0.1 to 1 mm between
the measuring faces.
Do not store the micrometer in a clamped state.

Functions
Origin point setting (ABS measurement system):
Resets the ABS origin at the current spindle position to the
minimum value of the measuring range and switches to ABS
mode.
Zero setting (INC measurement system):
A brief press on the ZERO/ABS button sets display to zero at
the current spindle position and switches to the incremental
(INC) measuring mode. A longer press resets to the ABS
measuring mode.
Auto power ON/OFF:
The reading on the LCD disappears after this instrument is
idle for about 20 minutes, but the reading and measurement
mode are retained. Turning the spindle causes the reading on
the LCD to reappear.
Data output:
Models equipped with this function have an output port for
transferring measurement data to a Statistical Process Control
(SPC) system.
Error alarm:
In the unlikely event of a display overflow or calculation
error, an error message is displayed and measurement stops.
Measurement cannot continue until the error is corrected.
Also, if the battery voltage drops below a certain point, the
battery indicator will turn on before measurement becomes
impossible, warning the user that the battery needs to be
replaced.
•The display is rotatable to enable easy reading from practically any direction. This feature is especially
useful in XY-table applications.
•The Digimatic output port enables inclusion in a statistical process control or networked measurement
system.

Quick Guide to Precision
Measuring Instruments
Micrometer Heads
Key Factors in Selection
Key factors in selecting a micrometer head are the measuring range, spindle face material and shape, accuracy, stem type, graduation style and thimble diameter.
■ Stem
■ Constant-Force Device
Plain stem
Stem locknut type
B
●The stem used to mount a micrometer head is classified as a plain or
locknut type as illustrated above. The stem diameter is manufactured to a
nominal Metric or Imperial size with an h6 tolerance.
●The clamp nut stem allows fast and secure clamping of the micrometer
head. The plain stem has the advantage of wider application and slight
positional adjustment in the axial direction on final installation, although it
does requires a split-fixture clamping arrangement or adhesive fixing.
●General-purpose mounting fixtures are available as optional accessories.
■ Measuring Face
Flat face
Spherical face
Micrometer head with
constant-force device
Micrometer head without constantforce device (no ratchet)
■ Spindle Lock
●If a micrometer head is used as a stop it is desirable to use a head fitted
with a spindle lock so that the setting will not change even under repeated
shock loading.
Anti-rotation device
●A flat measuring face is often specified where a micrometer head is used in
measurement applications.
●When a micrometer head is used as a feed device, a spherical face can
minimize errors due to misalignment (Figure A). Alternatively, a flat face on
the spindle can bear against a sphere, such as a carbide ball (Figure B).
●A non-rotating spindle type micrometer head or one fitted with an antirotation device on the spindle (Figure C) can be used if a twisting action on
the workpiece must be avoided.
●If a micrometer head is used as a stop then a flat face both on the spindle
and the object it contacts provides durability.
Figure A
●A micrometer head fitted with a constant-force device (ratchet or friction
thimble) is recommended for measurement applications.
●If using a micrometer head as a stop, or where saving space is a priority, a
head without a ratchet is probably the best choice.
Figure C
■ Measuring Range (Stroke)
●When choosing a measuring range for a micrometer head, allow an
adequate margin in consideration of the expected measurement stroke. Six
stroke ranges, 5 to 50 mm, are available for standard micrometer heads.
●Even if an expected stroke is small, such as 2 mm to 3 mm, it will be cost
effective to choose a 25 mm-stroke model as long as there is enough space
for installation.
●If a long stroke of over 50 mm is required, the concurrent use of a gauge
block can extend the effective measuring range. (Figure D)
Figure D
Figure B

■ Non-Rotating Spindle
● A non-rotating spindle type head does not exert a twisting action on a
workpiece, which may be an important factor in some applications.
●In this guide, the range (or stroke end) of the thimble is indicated by
a dashed line. For stroke ends, consider the thimble as moving to the
position indicated by the line when designing the jig.
■ Spindle Thread Pitch
■ Ultra-Fine Feed Applications
●The standard type head has 0.5 mm pitch.
●1 mm-pitch type: quicker to set than standard type and avoids the
possibility of a 0.5 mm reading error. Excellent load-bearing characteristics
due to larger screw thread.
●0.25 mm or 0.1 mm-pitch type
This type is the best for fine-feed or fine-positioning applications.
●Dedicated micrometer heads are available for manipulator applications,
etc., which require ultra-fine feed or adjustment of spindle.
B-99
■ Thimble Diameter
■ Graduation Styles
●The diameter of a thimble greatly affects its usability and the fineness of
positioning. A small-diameter thimble allows quick positioning whereas
a large-diameter thimble allows fine positioning and easy reading of the
graduations. Some models combine the advantages of both features by
mounting a coarse-feed thimble (speeder) on the large-diameter thimble.
●Care is needed when taking a reading from a mechanical micrometer head,
especially if the user is unfamiliar with the model.
●The normal graduation style, identical to that of an outside
micrometer, is the standard. For this style the reading increases as the
spindle retracts into the body.
●On the contrary, in the reverse graduation style the reading increases as the
spindle advances out of the body.
●The bidirectional graduation style is intended to facilitate measurement in
either direction by using black numerals for normal, and red numerals for
reverse, operation.
●Micrometer heads with a mechanical or electronic digital display, which
allow direct reading of a measurement value, are also available. These types
are free from misreading errors. A further advantage is that the electronic
digital display type can enable computer-based storage and statistical
processing of measurement data.

■ Guidelines for Self-Made Fixtures
A micrometer head should be mounted by the stem in an accurately machined hole using a clamping method that does not exert excessive force on the stem. There
are three common mounting methods as shown below. Method 3 is not recommended. Adopt methods (1) or (2) wherever possible.

■ Maximum Loading Capacity On Micrometer Heads
The maximum loading capacity of a micrometer head depends mainly on the method of mounting and whether the loading is static or dynamic (used as a stop, for
example). Therefore the maximum loading capacity of each model cannot be definitively specified. The loading limits recommended by Mitutoyo (at less than 100,000
revolutions if used for measuring within the guaranteed accuracy range) and the results of static load tests using a small micrometer head are given below.

was applied, in direction P, was measured.
(In the tests no account was taken of the
guaranteed accuracy range.)
Mounting method
Damaging / dislodging load*
(1) Locknut
Damage to the main unit will occur at 8.63 to 9.8kN (880 to 1000 kgf).
(2) Split-body clamp The main unit will be pushed out of the fixture at 0.69 to 0.98kN (70 to 100 kgf).
(3) Setscrew clamp Damage to the setscrew will occur at 0.69 to 1.08kN (70 to 110 kgf).
* These load values should only be used as an approximate guide.
