Using VT and CT
• When the voltage or current for the power line being measured
exceeds the maximum rated input for this device, use an external PT

measurement values directly.
Instrument Storage
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,
w
ith 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 radially from the inside to the
outside, and do no wipe with circular movements. Never use abra-
sives or solvent cleaners.
• Hioki shall not be held liable for any problems with a computer system
