2-2 Installing the Balance Caution The weighing unit and the display unit were adjusted as a unit. Therefore, make sure that the weighing unit and the display unit have the same serial number. The serial number is printed on the rear of the weighing unit and the display unit. The connection cable also carries the serial number. If the serial numbers of both units are different, the balance may not function properly. When a repair is necessary, submit both the weighing unit and the displa

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. Install the balance where it is free of dust. Install the b

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. Errors due to a static charge When the ambient humidity is less than 45% RH, insulators such as plastic or glass are prone to static electricity. When cha

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. Even very subtle air flow that is hard to be detected may influence the weighing Influence of the air flow operation. makes the weight value unstable Avoid those areas

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. Make each weighing gently and quickly to avoid errors due to changes in the enviro
