Tips
• Re-installing the battery will erase the ORIGIN (reference point) position. Perform reference
point setting again (refer to "4. ORIGIN (Reference Point) Setting").
• If an abnormal display is shown, such as an error display or not counting, etc., try removing the
battery and reinstalling.
Safety Precautions
To ensure operator safety, use this product in conformance with the directions, functions
and specifications given in this User's Manual.
Use under other conditions may compromise safety.
• Always keep batteries out of reach of children, and if swallowed, consult a physician immediately.
• Batteries should never be short-circuited, disassembled, deformed or come in contact with
extreme heat or flames.
•
If battery alkaline liquid comes in contact with the eyes, flush eyes immediately with clean
water and consult a physician. If battery alkaline liquid comes in contact with the skin,
flush the exposed area thoroughly with clean water.
• Never attempt to charge the primary battery or reverse the positive-negative terminals
when mounting. Improper battery handling or mounting may cause the battery to explode,
cause battery leakage and/or serious bodily injury or malfunctioning.
• Always handle the sharp measuring faces of this product with care to avoid injury.
• Do not disassemble or modify.
• Do not use or store the product in a place with sudden temperature changes. Adapt the
product to ambient temperature before use.
• Do not store the product in a place with high humidity or a lot of dust.
• Firmly close the battery compartment cover if the product is used in a place where it is
directly exposed to splashes of coolant, etc. For the type with output, when mounting the
output cable and cover, firmly tighten the fixing screws so that there is no gap. As well,
clean and apply anti-rust treatment after use. Rust may cause malfunction.
• Do not use submerged, as coolant ingress cannot be completely prevented. Complete
prevention of coolant ingress, etc., may also not be possible if the product is used in
locations exposed to direct jets of liquid.
• Do not apply excessive force or subject to sudden impacts such as dropping.
• Remove dust, cutting chips, etc. before and after use.
• When cleaning, wipe this product with a soft cloth moistened with diluted neutral
detergent. Do not use an organic solvent such as thinner, which may cause the product to
deform or malfunction.
• Rotating the thimble once will move the spindle 2 mm. Because the spindle moves quickly,
do not allow it to make violent contact with the measuring surface when measuring or
during reference point setting.
• The spindle structure prevents pulling out, so do not try to forcibly retract in excess of the
measurement range.
• Dirt on the spindle may lead to malfunction. If the spindle becomes dirty, wipe it clean with
a cloth containing a small amount of alcohol and apply a small amount of micrometer oil
(Part No. 207000).
• If Micrometer Oil is not available and you must use a commercially available product, we
recommend using an anti-rust agent with low viscosity almost equivalent to ISO VG10.
• Do not write numbers, etc. with an electric pen.
• If the product is to be out of use for three months or more, remove the battery before
storage. Liquid leakage from the battery may damage the product.

3. Precautions for Use
■Measuring Force
• Make sure to use the thimble ratchet or speeder ratchet to
ensure consistent measuring force.
• The appropriate measuring force is achieved with the
following procedure: make light contact between the
measurement surfaces and the workpiece, stop
momentarily, and then manually turn the thimble ratchet or
speeder ratchet about three to five times.
• Rotating the thimble once will move the spindle 2 mm.
Because the spindle moves quickly, be sure to make
contact slowly and gently with the measuring surface when
measuring or during reference point setting.
■Precautions for Measurement
• Use caution when measuring magnetized workpieces. If the product becomes magnetized,
measurement results may be affected.
■Precautions after Use
• After use, clean the entire product and check that none of
the parts are damaged.
If using in places exposed to water-based cutting fluid,
always apply anti-rust treatment after cleaning.
• For storage, leave a gap of 0.2 to 2 mm open for the
measurement surfaces, and release the swivel clamp.
• If the product will not be used for three months or longer,
apply micrometer oil (Part No. 207000) to the spindle to
prevent rust, and store it with its battery removed.
• If Micrometer Oil is not available and you must use a commercially available product, we
recommend using an anti-rust agent with low viscosity almost equivalent to ISO VG10.
4. ORIGIN (Reference Point) Setting
Reference point setting and measurement should be made in the same orientation
and conditions with the procedure as below.
■ORIGIN (Reference Point) Setting
1Clean both anvil and spindle measurement surfaces, together with the gage if it is used, to
remove all debris or dust.
2For 0 to 25 mm measurement range:
After making light contact with both measurement surfaces, stop momentarily, and then apply
the appropriate measuring force (refer to "■Measuring Force" in "3.Precautions for Use").
For above the 0 to 25 mm measurement range:
After clamping the gage between the measuring surfaces, bring the spindle into light contact
with the gage, stop momentarily, and then apply the appropriate measuring force (refer to
"■Measuring Force" in "3.Precautions for Use").
Use a periodically inspected (calibrated) gage (gauge block, setting standard for
outside micrometer, etc.).
