1-1 Operating precautions
■Do not wet the AC adapter.
That may cause an electric shock, short-circuiting or failure.
■Do not expose the AC adapter to dust.
That may cause an electric shock, short-circuiting or failure.
■Do not handle the AC adapter with wet hands.
That may cause an electric shock, short-circuiting or failure.
■Do not use the scale in a dust-filled room.
That may cause dust explosion or fire.
■Do not use the scale in explosive atmosphere.
That may cause explosion or fire.
Please order our explosive-proof scales to weigh in such a hazardous area.
■Obey the MSDS.
Measuring dangerous materials such as flammable liquid could cause an explosion or fire.
■Do not disassemble or modify the product.
Doing so could result in injury, electric shock, fire and other accidents or failures. For inspection and
adjustment, contact the retailer from whom the product was purchased.
■Do not move the product with a sample to be weighed set on the scale.
That may cause the sample to fall from the weighing pan, leading to a bodily injury or destruction of the
sample.
■Do not route the cables across passages.
The cables could be tripped on by a passed by and the scale could fall down and break or injure
someone.
■Do not use the product on an unstable table or a place that is subject to vibration.
That may cause the sample to fall from the weighing pan, leading to a bodily injury or destruction of the
sample. Besides inaccurate weighing may result.
■Do not place an unstable sample on the weighing pan.
The sample may fall down, giving rise to a danger. Put an unstable sample in a container (tare) before
weighing it.
■Do not use the product in an abnormal condition.
If it should happen that an abnormal event such as smoking or unusual odor occurs, ask the store
where you purchased the product or our sales department for repair. Keeping using the product may
result in an electric shock or fire. In addition, do not ever try to repair it for yourself, or very dangerous
situation is likely to occur.
■Only use the dedicated AC adapter.
Use of other types of power or adapters may result in heat generation or malfunction of the scale.

2
■Do not use the indicator unit in a wet/dusty location when AC adapter jack cover or
D-sub 9p connector covers are opened.
That may cause an electric shock, short-circuiting or failure.
■Do not connect to the AC adapter cord or communication cable with its connector or
jack being wet.
That may cause an electric shock, short-circuiting or failure.
■Do not install the scale in a place where it is directly exposed to airflow from air-
conditioning or heating equipment.
Due to changes in the ambient temperature, the scale could fail to accurately weigh samples.
■Do not install the scale in a place exposed to direct sunlight.
The internal temperature of the scale could rise, and the scale could fail to accurately weigh samples.
■Do not install the scale where the floor is soft.
When a sample is placed on the scale, the scale could slant and fail to accurately weigh samples.
■Do not install the scale in a place where the ambient temperature or humidity
change significantly.
The scale could fail to accurately weigh samples.
■Do not apply excessive force to or impact the scale.
Doing so could damage or result in failure of the scale. Carefully place samples on the scale.
■Do not use volatile solvents for cleaning anything other than the weighing pan.
The key panel, dust/waterproof packing or other resin components of could deform, and the scale no
longer maintains the dust/waterproofness. Wipe each unit using dry cloth or a cloth moistened with a
small amount of neutral detergent.
■Adjust (calibrate) the scale when it is installed or relocated.
Failure to do so might result in measurement errors. To ensure accurate measurements be sure to
adjust (calibrate) the scale.
■Check for an error periodically.
Use environment and chronological change cause an error in measured value, leading to an inaccurate
measurement.
■Unplug the AC adapter from the receptacle when the scale is not going to be used
for a long period of time.
Unplug the scale from the receptacle to save energy and prevent degradation.
■Always adjust the level of the scale before use.
A tilted scale generates errors which might cause inaccurate weighting.
■For proper disposal
This product including accessories may not be disposed of in domestic waste in conformance with
the specific requirements in your country, such as the European Directive 2012/19/EU on waste
electrical and electronic equipment (WEEE).
When you dispose of this product, please contact your local authorities or dealer and ask for the correct
method of disposal.

1-2 For more accurate measurement
To make more accurate measurement, it is necessary to lessen error-causing factors in measurement to
the extent possible. Error-causing factors include not only an instrument error and performance of the
scale itself but also the nature and condition of a specimen, measuring environment (vibration,
temperature, humidity, etc.) and the like. These factors will directly affect measurement result in the case
of a scale with high resolution capability.

1-2-1 Precautions related to measuring environment
Temperature/
humidity/
atmospheric
pressure
→ Try to keep the room temperature constant to the extent possible in order to
avoid condensation and indication drift due to change in temperature.
→ Low humidity is likely to cause generation of static electricity, resulting in
inaccurate measurement.
→ Change of atmospheric pressure is likely to cause change of buoyancy of the air
on the specimen, tare and mechanism of the scale, resulting in inaccurate
measurement.
Vibration/shaking → It is preferable to locate a measuring room on the first floor or the basement. The
higher the room is, the larger the vibration and shaking become. Therefore, a
highly located room is not suitable for measurement. Rooms near the railway or
road side should also be avoided.
Air draft → Places directly exposed to air current from an air-conditioner or to direct sun
generate abrupt temperature change and resultantly cause unstable weight
indication, and therefore, should be avoided.
Gravity → The latitude and altitude of a measuring location differentiate the gravity that
affects a specimen, giving a different weight indication to the same specimen.
Electromagnetic
wave
→ At a location where a strong electromagnetic wave generating object is in the
proximity of a scale, the scale is affected by the electromagnetic wave, making
the scale unable to indicate accurate weight, and therefore, such a location
should be avoided.
1-2-2 Precautions related to measuring table
Vibration/shaking → Vibrations during measurement destabilizes the indication of measurement
value, leading to inability to make accurate measurement. And so use of a
measurement table that is robust and hardly affected by vibration is required (a
vibration-proof structured table or concrete or stone-made table is suitable). In
addition, placing a sheet of soft cloth or paper under the scale causes shaking or
makes keeping horizontal attitude difficult, and therefore should be avoided.
→ The measurement table should be installed in a position free from vibration to the
extent possible. A corner rather than the centre of a room is less affected by
vibration and therefore more suitable for installation of the scale.
Magnetism/Static
electricity
→ Use of the scale on the table that is subject to magnetism or static electricity
should be avoided.
