■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 balance. ■Do not apply excessive force to or impact the balance. Doing so could damage or result in failure of the balance. Carefully place samples on the balance. ■Do not use volatile solvents. The main unit could deform. Wipe the main unit using dry cloth or a cloth moistened with a small amount of neutral detergent. ■Do not install the balance in a place where it is directly exposed to airflow from air-conditioning or heating equipment. Due to changes in the ambient temperature, the balance could fail to accurately weigh samples. ■Do not install the balance in a place exposed to direct sunlight. The internal temperature of the balance could rise and the balance could fail to accurately weigh samples. ■Do not install the balance where the floor is soft. When a sample is placed on the balance, the balance could slant and fail to accurately weigh samples. ■Do not install the balance in a place where the ambient temperature or humidity change significantly. The balance could fail to accurately weigh samples. ■Adjust (calibrate) the balance 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 balance. ■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 balance is not going to be used for a long period of time. Unplug the balance from the receptacle to save energy and prevent degradation. ■Always adjust the level of the balance before use. A tilted balance 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 balance 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 balance 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. 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 balance, the balance is affected by the electromagnetic wave, making the balance 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 balance 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 center of a room is less affected by vibration and therefore more suitable for installation of the balance. Magnetism/Static electricity → Use of the balance on the table that is subject to magnetism or static electricity should be avoided.

Turn them in the direction shown in the figure on the left to loosen them. 2 Level the^ balance.^ (1) While watching the level, turn the adjusters provided on the bottom to level the main unit. (2) Bring the bubble enters in the center circle as shown in the figure on the left. (3) When having leveled the main unit, slightly push the four corners of the balance to make sure that there is no rattle. Turn the adjusters as shown below depending on the position of the bubble in the level.
