Vernier Slide (Vernier Scale)
Proper alignment
PREPARATION FOR USE
Before using the caliper, follow the steps below:Do not apply excessive force to Vernier Slide.
Pushing against slide, or attempting to move without pressing
the Thumb Knob may cause damage or inaccuracy.
Wipe off any corrosion, dirt or oil from measuring
surfaces and slide.
Contamination of surfaces may cause measurement error.
Allow the caliper and object to be measured time to
reach the same temperature.
A temperature difference between the object to be measured
and the caliper may cause measurement error. Allow enough
time for the temperatures to equilibrate.
Performing an accuracy check.
Jaw Alignment
In closed position, make sure the measuring surfaces on the
outside jaws align properly and there is no gap (no light
should leak past.)
Confirm 0 points on scale (see diagram at below)
With jaws closed as in step above, make sure the reading
is zero and the vernier scale graduations align at the 0 and
39 positions as shown.
Depth Confirmation
Position caliper on a flat surface for depth measurement.
Reading should be 0 as in step above, with the vernier
graduations aligned at the 0 and 39 positions.
The measured value is determined by reading the main scale,
and then adding the Vernier Scale reading as determined by
the position where the vernier and main scale graduations align.
PREVENTING ERRORS
In order to prevent measurement error, please note the following.
AFTER USE CARE, STORAGE NOTES
Material : Stainless Steel
Measuring Range : 150mm
Resolution : 0.05mm
Maximum permissible error : 0.05mm
Weight : 150g
SPECIFICATIONS
As required, wipe slide and measuring surfaces with a dry cloth
treated with anti-corrosive oil. When not in use, apply
anti-corrosive treatment or keep in anti-corrosive bag.
When not in use, keep jaws slightly open to prevent thermal
expansion from creating excessive forces on jaws and affecting
accuracy.
Store in supplied case when not in use in a cool, dry location.
EXAMPLE
Measured value = Main Scale Reading + Vernier Scale Reading
EXAMPLE Measured Value: 73.50
EXAMPLE Measured Value: 73.55
POSITIONING CALIPER ON OBJECT
VIEWING THE SCALE
Flat surfaces
When measuring features
with flat surfaces, make sure
the measuring surface of the
jaws are parallel to the
surfaces to be measured.Cylindrical surfaces
When measuring cylindrical
features, make sure the
caliper jaws are
perpendicular to the cylinder
axis as shown.
Scale should be read from
directly above the calipers.
Due to step in height of
vernier scale relative to main
scale, if viewing direction is
not directly above the reading
may have parallax error.

SCRIBING CALIPERS
PRECISION
MEASURING TOOLS
Thank you for purchasing the SCRIBING CALIPERS.
This product is a precision measurement tool with a main scale and a vernier scale to indicate the measured value.
Carbide tipped measuring surfaces for scribing steel and hardened surfaces. For safe and proper use of this product, please read this instruction manual before use and follow the procedures described. Please
keep manual where it is accessible to user for future reference.
Keep this manual with the instrument if transferred or leased to a third party.
For inquiries about this product, please contact distributor or place of purchase.
SAFETY PRECAUTIONS Please Observe
Always follow the proper operating procedures in order to prevent
harm to yourself or others, and to prevent damage to property.
Read the manual and follow the instructions.Use of product other than as described in the manual
may cause accident.
Use only for measuring.Use for any purpose other than measuring may
damage or wear the instrument. Improper use may
also cause accident.
Handle with Care.Do not drop or subject instrument to excessive shock.
Do not place under heavy objects. Improper handling
may cause damage or poor accuracy.
Do not scratch instrument, for example by writing ID
number.
Indicates risk of personal injury or property damage if not followed.
WARNING
Denotes a prohibition
-You MUST NOT do
Denotes a requirement
-You MUST do
Use in proper environment. Please do not use instrument in rain or locations with
excessive humidity. Do not use at extreme high or
low temperatures. Keep out of direct sunlight.
Jaw Tips are sharp - Handle with care.Careless handling may cause injury.
Do not move the Vernier slide without pressing
Thumb Knob. Excessive force applied to Slide may cause damage
or affect accuracy.
Do not disassemble or modify.Do not remove the vernier slide, Please do not
attempt to disassemble or modify as it may cause
damage or poor accuracy.
CALIBRATION
In order to maintain instrument accuracy, it is recommended that
accuracy is confirmed through calibration on a periodic basis.
Wear of measuring surfaces from repeated use may affect accuracy and
periodic accuracy checks should be performed.
We provide calibration services.
Please contact agent in country of
purchase to make arrangements.
