Preface Thank you for purchasing one of the D-50 Series pH meters.
This meter is designed with a compact body that can be held in one hand and
features a water-resistant construction Note 1. It has a large-sized LCD display,
which enables to use the varied functions by simple operations, and especially
will be convenient to use on-location.
Carefully read this manual before using the meter.
Note 1:The water-resistant construction of this meter conforms to IP-67 of IEC
529, entitled “Water resistant testing and protection against penetration by solid
matter for electrical machinery and equipment.” To maintain the water-resistant
construction of this meter, follow the instructions in this manual when using the
meter.
IP-67 standards
・Dust does not get into internal parts.
・Water does not flow into internal parts when the meter is submerged 1 m
below the surface of the water for 30 minutes, at a temperature differential
between the water and the device of 5 ℃or less.
Warranty and Responsibility
Your meter iscoveredbywarrantyfor aperiodof one(1)year,under
normal use. Although unlikely, if any trouble attributableto us shouldoccur
duringthis period, necessaryexchange or repairs shallbeconductedbyus,

■Safety Precautions
For the safety use, be sure to read the following precautions:
WARNING:
●Do not use any unspecified AC adapters.
Heat or fire may occur to cause fire or accidents.
●Do not disassemble or modify the meter.
Heat or fire may occur to cause fire or accidents.
CAUTION:
●Do not use the serial communication or AC adapter in the place that
may possibly contact with moisture.
It may cause fire, electric shock, or breakage.
●Part of the electrode is made of glass; handle with care not to break it.
(WARNING)This indicates an potentially hazardous situation which,
if not avoided, will result in death or serious injury.
(CAUTION)This indicates a potentially hazardous situation which, if
not avoided, may result in minor or moderate injury. It
may also be used to alert unsafe practices.

■Cautionary Items
●Precautions
●Do not give physical shock to the meter like dropping or hitting.
●Do not immerse the meter into alcohol, organic solvent, strong
acid, strong alkaline, and other similar solutions. The meter
contains ABS resin, acrylic resin, and various rubber products in
its body.
●Do not use a hair-dryer for drying the meter. When the meter is
dropped into water or get wet, wipe it using soft cloth.
●Perform the key operation by the fingers, not by the hard object like
metal stick or rod.
●Be careful not to let water into the meter when the electrode connector
is empty or the AC adapter or serial communications cable has been
connected. In those states, the meter is not water-proof.
●To disconnect the electrode cable or interface cable, pull them out with
holding the connector part. Do not pull the cable part; it may cause a
breakage.
●Do not remove the battery gasket or twist it.
●When opening the battery case, make sure that no foreign matter is
attached to the battery gasket.
●Do not use any unspecified batteries ; it may cause a breakage.
●Location of use and storage
●The place which room temperature is at 0 ℃to 45 ℃
●The place which relative humidity is under 80% and free from
condensation
Do not use or store the meter at;
●The place of much dust
●The place with strong vibration
●The place with direct sunlight
●The place with corrosive gas generation
●The place near from an air-conditioner
●The place with direct wind
●Move and Transportation of the meter
To transport the meter, use the packaging box at the delivery.
Transportation by any unspecified packing methods may cause a
breakage.
●Disposal Standard solution used for the calibration must be under
neutralization before the disposal. As for the disposal of the meter,
treat it as an industrial waste.
