    11 3.2. When building into a system the ad-4212c is a precision balance. When it is built into a system, errors such as unstable weight values may occur due to static electricity, vibration, sample temperature and magnetism of the materials weighed or used for the devices near the balance. When usin...

    13 errors due to air flow and measures to take 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 operation. Avoid those areas as a weighing site. If weighing is ...
