Operation Precautions
Handling the Printer and Recording Paper
WARNING
The print head and surrounding metal parts can become hot. Be careful to avoid
touching these parts.
CAUTION
Be careful not to cut yourself with the paper cutter.
• Please use only the specied recording paper. Using non-specied paper may not only result in
faulty printing, but printing may become impossible.
• If the recording paper is skewed on the roller, paper jams may result.
• Always use the paper cutter to cut the printed paper. Excessive paper dust can accumulate on the roller
if the paper is cut by the print head, which may result in paper jams or white streaks in the printing.
Storing Data Recordings
The recording paper is thermally and chemically sensitized. Observe the following precautions to
avoid paper discoloration and fading.
• To avoid discoloration, do not expose it to direct sunlight. Store below 40°C (104°F) and 90% RH.
• Store away from dew and damp places.
• Make photocopies of recording printouts that are to be handled or stored for legal purposes.
• If the thermal paper is exposed to an organic solvent such as alcohol or ketone, it may no longer
develop properly, and recorded data may fade. Pressure sensitive tapes such as exible PVC
lms and scotch tapes must be handled with care as they contain organic solvents.
• Also, the thermal recording paper is ruined by contact with wet Daizo copy paper.
Avoid exposure to direct
sunlight.
Do not store thermal paper
above 40°C and 90% RH.
Avoid stacking with wet
Diazo copy paper.
Avoid exposure to volatile
organic solvents like
alcohol, ethers, and
ketones.
Avoid contact with
adhesive tapes like
soft vinyl chloride and
cellophane tape.
Storing Recording Paper
• Store thermal paper where its temperature will not exceed 40°C (104°F).
• The paper will deteriorate if exposed to light for a long time, so do not remove rolls from their
wrappers until ready to use.Handling Media

• With some external media, the instrument may not start up if power is turned on while the external
media is inserted. In such a case, turn power on rst, and then insert the external media. Prior
testing is recommended.
• Unusual USB ash drives, such as those that require ngerprint authentication or a password,
cannot be used.
• When saving or loading data, insert the storage media before selecting it. If the media is not
inserted, the le list display will not appear.
• All media (built-in drive, USB memory stick and CF card) have a limited service life. After
extensive use over a long period, data retention and readout may become stop working. In
such cases, you should procure new media.
• The built-in drive (SSD) is a consumable part. When the written data reaches the capacity (about
60 TB), no more data can be recorded. In such a case, the SSD should be replaced with a new
one.
• When the instrument is turned off for a long time (more than one year), the data stored on the
built-in drive (SSD) may be lost. Be sure to back up the data if the instrument is left turned off
for a long time.
• Automatic saving of data is possible only on built-in drive (SSD), USB memory stick and CF
card media.

Operation Precautions
Before Connecting Cables
When measuring power line voltage
• Connecting cables should only be connected to the secondary side of a breaker
Even if there is a short circuit on the secondary side of the breaker, the breaker
cuts off the electric supply. Do not connect to the primary side of a breaker
because unrestricted current ow could damage the instrument and facilities if
a short circuit occurs.
• To prevent electrical shocks and personal injury, do not touch any input
terminals on the VT (PT), CT or the instrument when they are in operation.
• Do not permanently connect the instrument in an environment where voltage
surges exceeding the maximum input voltage may occur. Failure to observe
this precaution could result in damage to the instrument or personal injury.
• Do not short-circuit two wires to be measured by bringing the connection cables
into contact with them. Arcs or such grave accidents are likely to occur.
• To avoid short circuit or electric shock, do not touch the metal parts of the
connecting cable clips.
• To avoid electrical shocks, be careful to avoid shorting live lines with the
connection cables.
DANGER
WARNING
• To avoid electric shock and short-circuit accidents, use only the specied test
leads to connect the instrument input terminals to the circuit to be tested.
• To avoid electric shock, do not exceed the lower of the ratings shown on the
instrument and connection cords.
To prevent an electric shock accident, conrm that the white or red portion
(insulation layer) inside the cable is not exposed. If a color inside the cable is
exposed, do not use the cable.
CAUTION
• The cable is hardened under the 0°C (32°F) or colder environment. Do not bend or
pull cables in such environments to avoid tearing insulation or breaking the cable.
• Connecting to the BNC jacks on modules
Do not use a metal BNC connector. If you connect a metal BNC cable to an insulated
BNC connector, the insulated BNC connector can be damaged and the instrument
may be damaged.
• To prevent cable damage, do not step on cables or pinch them between other objects.
Do not bend or pull on cables at their base.
IMPORTANT
• Use only the specied connection cables. Using a non-specied cable may satisfy the
specication requirements due to poor connection or other reasons.
• For detailed precautions and instructions regarding connections, refer to the instruction
manuals for your modules, connection cables, etc.
