  • Page 12: Precautions

    3. PRECAUTIONS To get the optimum performance from the balance and acquire accurate weighing data, note the following: 3-1 Before Use Install the balance in an environment where the temperature and humidity are not excessive. The best operating temperature is about 20°C / 68°F at about 50% relative humidity. Install the balance where it is not exposed to direct sunlight and it is not affected by heaters or air conditioners.

  • Page 13: When Building Into A System

    3-2 When Building into a System The AD-4212A/B is a precision balance. When it is built into a system and used, errors such as unstable weight values may occur due to static electricity, vibration and materials used for the devices near the balance. When using the balance that is built into a system, take the following precautions.
  • Page 14 Apply an anti-static agent onto plastic. When an operator is static charged If an operator’s clothes are static charged, especially in winter, it may be a cause for unstable weight values. Wear an anti-static wrist strap. Errors due to air flow Where the influence of ambient air flow is great such as: close to an air conditioner, door or passage way.

  • Page 15: During Use

    Magnetic material The balance uses a strong magnet as part of the balance assembly, so use much care when weighing magnetic materials. Place a non-magnetic object such as aluminum or brass between the sample and the balance, also keep an appropriate distance between them while weighing. 3-3 During Use To minimize the affect by electrical noises, earth ground the weighing unit and the display unit.
