Operating Precautions
11
• The storage temperature range is -10 to 50°C at relative humidity not
exceeding 80%.
• The battery pack should be removed when the instrument is stored.
Store the battery pack in a cool place.
• The instrument should be recalibrated before use after long-term stor-
age.
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
or CT.
• When using an external PT or CT, make sure you use a device with a
minimal phase difference. By setting the PT or CT ratio, you can read
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,
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 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
that arises from the use of this CD, or for any problem related to the
purchase of a Hioki product.
