els of particulate dust
Transporting and Handling
To avoid damage to the instrument and sensors, protect it from physical
shock when transporting and handling. Be especially careful to avoid
physical shock from dropping.

Operating Precautions
7
Before using the instrument the first time, verify that it operates normally to ensure
that the no damage occurred during storage or shipping. If you find any damage, con-
tact your dealer or Hioki representative.
CD Handling
• Always hold the disc by the edges, so as not to make fingerprints on
the disc or scratch the printing. Never touch the recorded side of the
disc. Do not place the disc directly on anything hard.
• Do not wet the disc with volatile alcohol or water, as there is a possibil-
ity of the label printing disappearing.
• To write on the disc label surface, use a spirit-based felt pen. Do not
use a ball-point pen or hard-tipped pen, because there is a danger of
scratching the surface and corrupting the data. Do not use adhesive
labels.
• Do not expose the disc directly to the sun's rays, or keep it in condi-
tions of high temperature or humidity, as there is a danger of warping,
with consequent loss of data.
• To remove dirt, dust, or fingerprints from the disc, wipe with a dry
cloth, or use a CD cleaner. Always wipe from the inside to the outside,
and do no wipe with circular movements. Never use abrasives or sol-
vent cleaners.
• Hioki shall not be held liable for any problems with a computer system
that arises from the use of this CD, or for any problem related to the
purchase of a Hioki product.
Preliminary Checks
Before using the instrument, make sure that the insulation on the
sensor cables is undamaged and that no bare conductors are
improperly exposed. Using the instrument in such conditions
could cause an electric shock, so contact your dealer or Hioki rep-
resentative for replacements.

Measurement Preparation to Data Analysis
