WARNING
External power is supplied to the instrument from an AC power source, through an AC
adapter. Use only the AC adapter specified by Mitutoyo(No.526688A,D,or E/standard
accessory).
If the instrument is used near a device requiring high voltage, frequency or current, be
sure that this device and the instrument's AC adapter have separate power supplies.
Use only an AC power supply which conforms to the voltage and frequency written on
the AC adapter. Using a voltage or frequency outside the allowed range may result in
fire or explosion.
When not using the instrument for an extended period, always unplug the AC adapter
from the power supply to avoid the risk of fire.

CAUTION
Do not knock, drop or subject the instrument to excessive force.
Do not disassemble or modify the instrument.
Do not operate the keys with a pointed instrument (such as a screwdriver).
Avoid use or storage of the instrument in direct sunlight, or in extremely hot or cold
areas.
Use of the instrument in areas of low or high atmospheric pressure may cause
instrument failure due to material deterioration.
Do not store the instrument in a highly damp or dusty environment. Avoid getting water
or oil on the instrument during use.
Do not use an electric marking or other high voltage device near the instrument.
Electronic parts in the instrument may be damaged. Use in areas where a large amount
of electrical noise is present may result in malfunction.
Secure the instrument with a dial gage stand or similar fixture in a vibration-free
environment.
Do not subject the spindle to a vertical load or torsion.
To clean the instrument, use a dry soft cloth or cotton swab, or one soaked in diluted
neutral detergent. Use of organic solvents (such as thinner or benzene) may result in
failure.
The spindle may not move smoothly if it becomes dirty. To clean the spindle, wipe it first
with a cloth soaked in alcohol, and then gently with a cloth containing a small amount of
low-viscosity oil.
To maintain measuring accuracy, take note of the following point.
IMPOTANT
In areas of significant temperature fluctuation, thermal expansion of component
parts may cause the measured origin to shift from the set origin. Use the instrument
in a temperature-controlled room with as little temperature fluctuation as possible.
Before starting measurement, allow the instrument and the item measured sufficient
time to thermally stabilize.
