■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 DO electrodes is highly potassium hydroxide (KOH).

If the internal solution comes in contact with the skin, wash it off

immediately. If it gets into eyes, flush with plenty of water and then consult a

doctor.

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

●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.

・The function that measuring dissolved oxygen of the instrument is only usable for

measuring under water. Do not use this function for the application except described

above.

・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.

For your safety

VIII

・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.

●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.
