2. Preparation for Measurement
1) Setup
NOTICE
• Confirm that the measuring head or screw is not loosened before use.
• Do not insert, remove, or turn the indicator with the clamp screw tightened, as it will lead to
breakage.
• If the insertion hole of the indicator holder is accidentally deformed, correct it by inserting a
ø8 mm rod for the metric type and a ø9.53 mm rod for the inch type.
• Secure fixation may be impossible when the indicator or the indicator holder insertion hole or
the clamp screw is dirty. Clean them in advance.

and specifications given in this User’s Manual.
Use under other conditions may compromise safety.
NOTICE
• Do not disassemble or modify. This may cause damage.
• Do not use or store the product in a place with sudden temperature changes. Adapt the
product to room temperature before use.
• Do not store the product in a place with high humidity or a lot of dust.
• Do not apply impact or excessive force to this product.
• Be sure to perform reference point setting before measurement.
• Remove dust, cutting chips, etc. before and after use.
• After use, clean and perform anti-rust treatment for the body, anvils, adjustment washers,
etc. Insufficient cleaning may cause accuracy or operation to suffer.
• For periodic calibration or precision measurement, wear thick gloves in order to reduce
changes in the indicated value caused by the transmission of body temperature.
• Indicators with rubber bellows such as waterproof dial gages cannot be used.
Tips
The bore gage is a comparator. It will not function as a measuring instrument if used alone.
An indicator such as a dial gage and a reference gage such as a set ring or micrometer are
required to use the product.
