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 Lock 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.
①
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.)
②
Confirm
“
0
”
points on scale (see diagram at right)
With jaws closed as in step
①
above, make sure the reading is zero and
the vernier scale graduations align at the
“
0
”
and
“
39
”
positions as shown.
③
Depth Confirmation
Position caliper on a flat surface for depth measurement. Reading should
be
“
0
”
as in step
②
above, with the vernier graduations aligned at the
“
0
”
and
“
39
”
positions.
READING THE SCALE
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.

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.

Proper alignment
＜
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.
