■Safety precautions
This section provides precautions for using the product safely and correctly and to
prevent injury and damage. The terms of DANGER, WARNING, and CAUTION indicate
the degree of imminency and hazardous situation. Read the precautions carefully as it
contains important safety messages.
●Instrument and electrode
WARNING
Do not use an unspecified AC adapter.
Otherwise, it may heat up or be ignited resulting in a fire or an accident.
Do not disassemble or modify the instrument.
Otherwise, it may heat up or be ignited resulting in a fire or an accident.
CAUTION
Harmful chemicals
The internal solution of pH electrode is highly concentrated potassium
chloride (3.33 mol/L KCl). If the internal solution comes in contact with the
skin, wash it off immediately. If it gets into the eyes, flush with plenty of water
and then consult a doctor.
Broken glass
Broken glass may cause injury. The outer tube and tip of an electrode are
made of glass. Handle them with care.
Do not use the RS-232C communication and the AC adapter under wet or
humid conditions. Otherwise, it may cause a fire, electric shock, or
breakage.

For your safety
VI
●Battery
WARNING
Keep batteries out of reach of children. If someone accidentally swallows a
battery, consult a doctor immediately.
If alkaline fluid from a battery gets into the eyes, do not rub the eyes, rinse
with clean water immediately and then consult a doctor.
Contact with alkaline fluid could cause blindness.
Do not put batteries in a fire, expose to heat, disassemble or remodel.
Doing so could case fluid leakage, overheating or explosion.
CAUTION
Do not remove or scratch the external label of the battery.
Doing so could cause injury to hands and fingers.

■Product handling information
●Operational precautions (instrument)
・Only use the product including accessories for their intended purpose.
・Do not drop, crash, or give any physical impact on the instrument.
・The instrument is made of solvent-resistant materials but that does not mean it is
resistant to all chemicals. Do not dip the instrument in strong acid or alkali solution, or
wipe with such solution.
・If the instrument is dropped into water or gets wet, wipe it using soft cloth. Do not heat
to dry it with a hair-dryer (or the like).
・The instrument has a dust-proof and waterproof structure. Waterproof performance is
following specification: the instrument does not malfunction even when immersed in
water of 1 m depth for 30 minutes.
This does not mean to guarantee non-destructive, trouble-free, dust-proof, and
waterproof performance in all situations. If the instrument is correctly handled
according to the descriptions in this manual, the instrument provides dust-proof and
waterproof performance.
・When replacing the batteries with an AC adapter or a serial cable connected the
instrument does not have the dust-proof and waterproof performance. The dust-proof
and waterproof performance is maintained only when the covers are attached
correctly.
・After replacing the batteries with an AC adapter or a serial cable connected make sure
that the waterproof packing attached to each cover is not deformed or discolored, or
has foreign matter adhering to it. If the waterproof packing is deformed, discolored or
has foreign matter adhering to it, or dust could get inside, water leaks could occur that
could lead to instrument malfunction.
・To disconnect an electrode, AC adapter cable or serial cable, hold the connector and
pull it off. If you pull at the cable, it may cause a breakage.
・The RS-232C communication between the instrument and a personal computer
(referred to as PC in the rest of this document) may fail because of environmental
conditions, such as (radio/electromagnetic) noise.
・Do not replace the batteries in a dusty place or with wet hands while an AC adapter or
a serial cable is connected. Dust or moisture could get inside the instrument, possibly
causing instrument malfunction.
・Do not use the tip of a nail or an object with a sharp end to press the keys.
・If the power supply is interrupted while measurement data is being saved in the
instrument, the data could be corrupted.
・A NiMH rechargeable battery can be used in this instrument, but the battery used in
the instrument cannot be charged using the AC adapter.

For your safety
VIII
●Operational precautions (battery)
・Do not short circuit a battery.
・Set the + and side of the battery correctly.
・When the battery has run out or the instrument will not be used for a long time, remove
the batteries.
・Of the specified battery types, make sure to use two batteries of the same type.
・Do not use a new battery together with a used battery.
・Do not use a fully charged nickel-metal hydride battery together with a partially
charged battery.
・Do not attempt to charge a non-rechargeable battery.
●Environmental conditions for use and storage
・Temperature: 0°C to 45°C
・Humidity: under 80% in relative humidity and free from condensation
Avoid the following conditions.
・Strong vibration
・Direct sunlight
・Corrosive gas environment
・Close to an air-conditioner
・Direct wind
●Transportation
When transporting the instrument, repackage it in the original package box. Otherwise, it
may cause instrument breakage.
●Disposal
・Standard solution used for the calibration must be under neutralized before the
disposal.
・When disposing of the product, follow the related laws and/or regulations of your
country for disposal of the product.
