Safety precautions
WARNING
THIS PRODUCT CONTAINS A BUTTON BATTERY
If swallowed, a lithium button battery can cause severe or fatal injuries within 2 hours. Keep
batteries out of reach of children.
If you think batteries may have been swallowed or placed inside any part of the body, seek
immediate medical attention.
Do not put batteries in a fire, expose to heat, disassemble or remodel. Doing so could case fluid leakage, overheating or
explosion.
Before disposing of batteries, wrap the terminals with tape to insulate.
If a battery is allowed to come in contact with other metal or batteries, it may cause heating, destruction, and fire.
Wash off any calibration fluid that comes into contact with hands or other exposed skin. If fluid gets in eyes, rinse them
immediately and see a doctor.
3200965346.book 2 ページ ２０２３年１２月１４日 木曜日 午前８時２６分

CAUTION
Incorrect use of batteries may cause leakage or bursting of the butteries and result in product damage
or burn injury.
• Connect the positive and negative terminals of the battery correctly.
• Do not mix different battery types in the same device.
• Replace all of the batteries in the same device at the same time.
• Do not attempt to recharge batteries.
• Do not solder a battery.
• Store in a location away from direct sunlight, high temperature, and high humidity.

Handling precautions
Meter and sensor
The sensor is a consumable part. If it becomes damaged or its performance deteriorates, replace it
with a new one (the sensor cannot be repaired).
Do not swing the meter and sensor using a strap.
Do not drop the meter or apply excessive force to it.
Do not leave the meter in areas of direct sunlight or high temperature/humidity.
Do not clean the meter with organic solvents.
Neither the meter nor sensor is waterproof by itself. The sensor must be securely mounted on the
meter before use.
To ensure the waterproof performance, confirm the followings when attaching the sensor.
• The waterproofing gasket is clean and undamaged.
• The waterproofing gasket is seated properly in the groove with no twisting or warping.
• he meter and sensor are not deformed.
The flat sensor is made of thin material. Take care not to break it.
If the sensor is damaged, remove it from the meter avoiding injury and dis-
pose of it in a plastic bag.
0.2 mm

The batteries provided have been used for performance testing. Therefore, their service life may be short.
The battery alarm icon lights up when the battery voltage is low. Replace the batteries when the battery alarm icon (BATT)
lights up. The meter power may not be switched ON/OFF when the battery voltage is low.
Manufacturing date can be identified from MFG No. described in the ID label on the backside of the instrument.
The number from the middle in the MFG No. indicates manufacturing year and next alphabet indicates manufacturing month. The
alphabet is assigned to month according to the table below.
Ex.: ID: XX23M000 means the device manufactured in 2023 December.
Do not measure samples such as the following, since they may damage the sensor or shorten its life.
・Organic solvents ・Oils ・Adhesives ・Cement ・Alcohols ・Surfactants
・Concentrated acid (0 pH to 2 pH) ・Concentrated alkaline (12 pH to 14 pH)
If the sensor is damaged physically or chemically, stop using the sensor.
For some samples (such as pure water), the measured value may be unstable. This is natural.
A small amount of liquid or white powder may appear on the liquid junction of the flat sensor. The appearance of this powder
or solution is normal. Simply rinse it off with water before use.
