Product Handling Information
Operational Precautions
٨
Do not drop, crash, or give any physical impact on the instrument.
٨
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.
٨
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).
٨
Use fingers to press the operation keys or the touch panel.
Do not use a hard object like a metal stick or rod.
٨
Be careful not to let water into the instruction inside.
The instrument is not water-proof.
٨
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.
٨
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.
٨
RS-232C or USB communication between the instrument and a personal computer may fail because of environmental conditions, such
as (radio/electromagnetic) noise.
Environmental conditions for use and storage
٨
Temperature: 0qC to 45qC
٨
Humidity: under 80% in relative humidity and free from
condensation
Avoid the following conditions:
٨
Dusty environment
٨
Strong vibration
٨
Direct sunlight
٨
Corrosive gas environment
٨
Close to an air-conditioner
٨
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.
