WARNING
Keep batteries out of reach of children. If
someone accidentally swallows a battery, call
a doctor immediately.
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 termi-
nals 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.
CAUTION
Incorrect use of batteries may cause leakage
or bursting of the butteries and result in prod-
uct 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.
Meter and sensor
The sensor is a consumable part.
If it becomes damaged or its per-
formance deteriorates, replace it
with a new one (the sensor can-
not be repaired).
Do not swing the meter and sen-
sor using a strap.
Do not drop the meter or apply
excessive force to it.
Do not leave the meter in areas of direct sun-
light 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.
• The meter and sensor are not deformed.
The flat sensor is made of thin material.
Take care not to break it.
If the sensor is dam-
aged, remove it from
the meter avoiding
injury and dispose of
it in a plastic bag.
Do not measure samples such as the follow-
ing, since they may damage the sensor or
shorten its life.
• Organic solvents
• Oils
• Adhesives
• Cement
• Alcohols
• Concentrated acid (0 to 2 pH)
• Concentrated alkaline (12 to 14 pH)
• Surfactants
If the sensor is damaged physically or chemi-
cally, stop using the sensor.
0.2 mm
For some samples (such as pure water), the
measured value may be unstable. This is natu-
ral.
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.
Battery
The batteries provided have been used for per-
formance testing. Therefore, their service life
may be short.
The battery alarm icon lights up when the bat-
tery voltage is low. Replace the batteries when
the battery alarm icon lights up. The meter
power may not be switched ON/OFF when the
battery voltage is low.
Identification of manufacturing date
Manufacturing date can be identified from MFG
No. described in the ID label on the backside of
the instrument.
Third number from the left in the MFG No. indi-
cates manufacturing year. Forth alphabet from
the left in the MFG No. indicates manufacturing
month. The alphabet is assigned to month
according to the table below.
Ex.: ID: AA6A0000 means the device manufac-
tured in 2016 January.
