■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.
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 can not 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
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 or USB communication and the AC adapter under
wet or humid conditions. Otherwise, it may cause a fire, electric shock, or
breakage.

■Product handling information
●Operational precautions
・Only use the product including accessories for their intended purpose.
・Do not drop, crash, or give any physical impact on the instrument.
・Do not immerse the instrument into alcohol, organic solvent, strong 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 personal computer
(referred to as PC in the rest of this document) 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.
・Strong vibration
・Direct sunlight
・Corrosive gas environment
・Close to an air-conditioner
・Direct wind
・Dusty environment
●Transportation
When transporting the instrument, repackage it in the original package box. Otherwise, it
may cause instrument breakage.

For your safety
VIII
●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.
