Overvoltage Categories (CAT )
To ensure safe operation of measurement instruments, IEC 60664
establishes safety standards for various electrical environments,
categorized as CAT I to CAT IV, and called overvoltage categories.
These are defined as follows.
3
1
CAT I Secondary electrical circuits connected to an AC
electrical outlet through a transformer or similar
device.
CAT II Primary electrical circuits in equipment connected to
an AC electrical outlet by a power cord (portable
tools, household appliances, etc.)
CAT III Primary electrical circuits of heavy equipment (fixed
installations) connected directly to the distribution
panel, and feeders from the distribution panel to outlets.
CAT IV The circuit from the service drop to the service
entrance, and to the power meter and primary overcurrent protection device (distribution panel).
Higher-numbered categories correspond to electrical environments
with greater momentary energy. So a measurement device
designed for CAT III environments can endure greater momentary
energy than a device designed for CAT II.
Using a measurement instrument in an environment designated
with a higher-numbered category than that for which the instrument
is rated could result in a severe accident, and must be carefully
avoided.

Care and Handling of CD-R
• 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
possibility 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-tippe d 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
conditions of high temperature or humidity, as there is a danger
of warping, with consequent loss of data.
• T o remove dirt, dust, or fi ngerprints 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 abrasives or solvent cleaners.
