3. Precautions for Use
Indicates a potentially hazardous situation which, if not avoided, may result in
property damage.
NOTICE
• Do not use an electric engraver to put marks on the product such as numbers.
• Do not drop the product or apply excessive force to it.
• Do not scratch the main scale surface.
• Keep the operation temperature and storage temperature.
• After use, take corrosion prevention measures. Corrosion can cause the product
to malfunction.
• If the product will not be used for more than three months, remove the battery
from and store it properly. Otherwise, liquid may leak from the battery and
damage the product.
• For protecting the detection/display module from dust and water su󰀩ciently,
tighten the setscrews to secure the battery compartment lid. Also do not remove
the packing seal.
• - Before using this product for the rst time, wipe the rust preventive oil from the product
with a soft cloth soaked with cleaning oil, and install the supplied battery.
• - If rust preventive oil is dried, the product might not operate smoothly. Wipe a sliding
surface with a cloth and then apply a little oil to use the product. This can make the
product operate smoothly.
4. Product Applications
Outside measurement Inside measurement
Step measurement Depth measurement
5. Basic Usage
■Using the caliper
Grasp the beam lightly with your right hand, put your right thumb on the thumb rest, and
move the slider horizontally to measure.
■Fixing the slider
The measurement value readings are usually taken with the workpiece clamped (or in
close contact). However, depending on the measuring location, the orientation during
measurement and so on, it may be di󰀩cult to get a reading in this position. In this case,
tighten the slider clamp screw, move the caliper carefully away from the workpiece, and
read the display.
■Using the thumb roller
The thumb roller is a ne feeding device, and not a constant-force device. Measuring
force tends to be large when measuring with the thumb roller. Carefully apply an
appropriate and even measuring force when using the thumb roller.
■Using the switch (about Icons)
6. ConrmationbeforeMeasurement
■ConrmingSliderMovement
•Conrm that there is no irregular slider movement and that the slider moves smoothly
throughout the measurement range.
•Conrm that there is no play of the slider in the vertical direction against the sliding
surface.
■ConrmingClearance(Wear)betweenMeasuringsurfaces
•When the outside measuring jaws are closed and
held to the light, conrm that there is no slit observed
between the jaws against the light, or that a faint light
is uniformly visible. As well, conrm that the jaw tips
are not deformed.
•When the inside measuring jaws are closed and held
to the light, observing the jaws obliquely, conrm that
a light is uniformly visible, and that the tips are not
deformed.

9. Measurement Method
Indicates a potentially hazardous situation which, if not avoided, could result in
death or serious injury.
WARNING
Do not measure the workpiece with the caliper if it is rotating, etc.
Measuring surfaces will be worn out.
■Outside measurement
Picture: Vernier caliper
• Do not apply excessive force to the workpiece.
Excessive measuring force will cause measurement
error because of the positional deviations of the jaws.
OKNG

L2
L1 < D
• Do not clamp the workpiece diagonally.
Measurement error will ensue if tilted.
OKNG
• Clamp the workpiece as close to the sliding surface as
possible. Measurement error is more likely to increase
if clamped near the outside measuring jaw tips.
OKNG
1 Insert the workpiece into the outside measuring jaws and bring jaws
into close contact with the workpiece, using appropriate and uniform
measuring force.
2 Read the display while keeping the outside measuring surfaces in close
contact.
■Inside measurement
Picture: Vernier caliper
• Insert the inside measuring jaws as deeply as possible
into the workpiece. OKNG
NG
• For inner diameter measurement, bring the inside
measuring surfaces into close contact, and read the
display when it is maximum: a direct line between the
measuring surfaces passes through the center of the
cross-section. OKNG
• For groove width measurement, bring the inside
measuring surfaces into close contact, and read the
display when it is minimum: a direct line between the
faces is perpendicular to the groove inner wall. OKNG
1 Insert the inside measuring jaws into the workpiece, and bring jaws into
close contact with the workpiece interior using appropriate and uniform
measuring force.
2 Read the display while keeping the inside measuring surfaces in close
contact.

6No. 99MAD030A
■Step measurement
Picture: Vernier caliper
• Do not use a depth bar for step measurement, as the
small contact area with the workpiece makes it di󰀩cult to
retain a stable orientation. NG
• For a stepped workpiece, bring the entire step measuring
surfaces (①, ②) into close contact with the workpiece.

1 Bring the step measuring surface (①, beam side) into close contact with
the workpiece.
2 Move the slider until the step measuring surface (②, slider side) strikes
the workpiece (stepped surface).
3 Read the display while keeping the step measuring surfaces in close
contact.
■Depth measurement
Picture: Vernier caliper
The depth measuring surface of the caliper
is narrow and unstable. Bring it into contact
perpendicular with the workpiece.

10. Errors and Countermeasures
■Minimum digit “E” display
This digit appears if the surface of the scale is dirty to an
immeasurable degree. Clean the surface of the scale cover.
If “E” still appears even after the surface of the scale cover is
cleaned, reinstall the battery. Nevertheless, if it does not disappear,
remove the battery, and then contact your distributor or sales o󰀩ce.
■“B”, “ ” and “Err--b” display
B
“B” indicates the voltage drop of the battery.
Replace the battery immediately. (For
instructions on replacing the battery, see “8.”).
■Ifallvedigitshavethesamenumber,orif“H”blinks
Remove the battery temporarily, and then reinstall it.
■Other errors
If the error shown in the gure
occurs, set the origin again.
11. Precautions after Use
•If there is dirt on the measuring surface, reference surfaces, sliding surface, etc., wipe it
away with a dry cloth or a cloth slightly moistened with alcohol.
•For long-term disuse, wipe away any dirt carefully and apply a light coating of rust
preventive oil before storage.
•Do not store in locations with high temperatures, low temperatures, high humidity, or
exposure to direct sunlight.
