Operating Precautions
7
Handling the Instrument
To avoid electric shock, do not remove the instrument's case. The internal com-
ponents of the instrument carry high voltages and may become very hot during
operation.
Never modify the instrument. Only Hioki service engineers should disassemble
or repair the instrument. Failure to observe these precautions may result in fire,
electric shock, or injury.
• To avoid damage to the instrument, protect it from physical shock when trans-
porting and handling. Be especially careful to avoid physical shock from drop-
ping.
• Before transporting the instrument, disconnect all cables and remove any CF
card, USB memory stick and recording paper.
Handling the Probes
• Avoid stepping on or pinching cords, which could damage the probe insulation.
• To avoid breaking the cords, do not bend or pull them.
Use only the specified connection cords. Using a non-specified cable may result
in incorrect measurements due to poor connection or other reasons.
Handling the CD
• Always hold the disc by the edges, so as not to make fingerprints on the disc or
scratch the printing.
• 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-tipped pen, because there is a danger of scratching the sur-
face 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.
• 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 abrasives or solvent cleaners.
• Hioki shall not be held liable for any problems with a PC system that arises
from the use of this CD, or for any problem related to the purchase of a Hioki
product.
