●Safety precautions
This section provides precautions to enable you to use 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.
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 meter.
Otherwise, it may heat up or be ignited resulting in a fire or an accident.
Fire
• For your safety, make sure to unplug the power plug from the electrical outlet
when not in use.
• Clear dust on the power plug periodically (a few times a year).
If the power supply cord is left plugging into the electrical outlet for a long period of
time, electrical tracking may occur due to dust and moisture, and it may result in an
ignition or a fire.
Fire or electric shock
• Do not bundle the power supply cord during use.
• Do not damage the power supply cord nor apply an excessive load to it, such as
bending and stretching it repeatedly, putting a heavy thing on it.
• If it cannot be plugged into an electrical outlet firmly, stop use of the power
supply cord.
If may result in overheating, a fire, an electrical shock, or breakdown.
CAUTION
Harmful chemicals
Some ion electrodes are used with hazardous standard solutions. Handle them
with care.
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 an 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 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.

acid, strong alkaline, or the like. The instrument body contains ABS
resin, acrylic resin, and some rubber parts.
●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).
●Use fingers to press the operation keys or the touch panel.
Do not use a hard object like a metal stick or rod.
●Be careful not to let water into the instruction inside.
The instrument is not water-proof.
●To disconnect an electrode or interface cable, hold the connector and
pull it off. If you pull at the cable, it may cause a breakage.
●The touch panel is capacitance-type. Make sure to turn OFF the
power before cleaning the panel. If you wipe it with the power ON, it
may cause instrument malfunction.
●RS-232C or USB communication between the instrument and a per-
sonal computer may fail because of environmental conditions, such
as (radio/electromagnetic) noise.
●Make sure to use the provided power supply cable to power this
product.
●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:
●Dusty environment
●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. As for the disposal of the meter, treat it as an
industrial waste.
