immanency and hazardous situation. Read the precautions carefully as it contains important
safety messages.
• Instrument and electrode
Do not disassemble or modify the instrument. Otherwise, it may heat up or be ignited
resulting in a fire or an accident.
Harmful chemicals
Some electrodes are used with hazardous standard solutions. Handle them with care.
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 phono jack under wet or humid conditions. Otherwise, it may cause a
fire, electric shock, or breakage.

For Your Safety
VIII
• Battery
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 can case fluid leakage, overheating or explosion.

Product Handling Information
IX
• Product Handling Information
• Operational precautions (instrument)
• Only use the product including accessories for their intended purpose.
• Do not drop or physically impact the instrument.
• The instrument is made of solvent-resistant materials but that does not mean it is resistant
to all chemicals. Do not expose 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.
• The instrument has a dust-proof and waterproof structure i.e., the instrument does not
malfunction even when immersed in water of 1 m depth for 30 minutes. This does
guarantee non-destructive, trouble-free, dust-proof, and waterproof performance in all
situations.
• When replacing the batteries or when 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 or removing the serial cable connected, make sure that the
waterproof gasket attached to the cover is not deformed or discolored, or has foreign
matter adhering to it. If the waterproof gasket is deformed, discolored or has foreign matter
adhering to it, dust could get inside, water leaks could occur that could lead to instrument
malfunction.
• To disconnect an electrode or serial cable, hold the connector and pull it off. If you pull at
the cable, it may cause breakage.
• The phono jack 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 electromagnetic noise.
• Do not replace the batteries in a dusty place or with wet hands. Dust or moisture could get
inside the instrument, possibly causing instrument malfunction.
• Do not use 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.
• Operational precautions (battery)
• Do not short circuit a battery.
• Position the + and side of the battery correctly.
• When the battery has depleted 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.

Product Handling Information
X
