Electrostatically charged samples/containers (e.g. glass or plastic) or very low humidity may cause non-repeatable values or drifts in one direction. Shield the sample with metal foil or a metal container, increase the humidity and neutralize static electricity with an ionizing blower.
Magnetic force fields can lead to stable but non-repeatable values, or changes in display based on the sample’s position. Avoid using magnetic stirring bars, shield samples with Mumetal foil or non-magnetic objects, use anti-magnetic weighing pans and demagnetize the pan before weighing.
