11 3-2 When Building into a System The AD-4212A/B is a precision bal ance. When it is built into a sy stem and used, errors such as unstable weight values may occur due to static electricity , vibr ation and materials used for the devices near the balance. When using the balance that is built into a system, take the following precautions.  Error[...]

12 When an o perator 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-st atic wrist strap.  Errors due to air flow Where the i nfluence of am bient air flow is great such as: close to an air conditioner , door or passage way . Even very subtle [...]

13 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 alum inum or brass between the sample and the balance, also keep an appropriate dist ance between them while weighing. 3-3 During Use  T o minimize the affect by electr[...]
