① Place the Tape around the surface to be measured.
②
Pass the end of the Tape through the Reader as shown below.
③ Hold the Reader secure and pull the Tape tight. Make
sure the Tape is not at an angle, and is in full contact
with the workpiece.
Keep Tape straight
④ Read the diameter or circumference measurement.
●
When taking a reading, make sure the Reader is tight against
the Tape, and read from directly in front of the Scale. Reading
at an angle may cause measurement error.
When reading diameter and circumference, for each reading
hold the Tape in place and take a reading. If attempting to read
both simultaneously, the measurement may not match a
calculated value due to how the Tape is held.

NOTE: When using model CJU-950BKD
HOW TO USE
AFTER USE CARE ・STORAGE
● Using a dry cloth, wipe off any dirt or oils.
Store in a safe place, out of harm's way.
If stored under heavy object, or subject to excessive
forces, the tape may be bent and become inaccurate.
Store in a cool, dry, and dark location.
Avoid direct sunlight or high humidity, and access from
unauthorized users.
The measurement is determined by reading the Main Scale,
and then adding the Vernier Scale reading determined by the
position where the Vernier and Main Scale graduations align.
For small diameter workpieces, account for the error
when taking a measurement.
