A term used to indicate that the scale is approved for use in commercial transactions, where items are bought and sold by weight, volume and/or length; though there may be additional applications for which approved scales must be used (Prescribed Applications). Legal For Trade (LFT) standards seek to make sure that the scale or balance performs consistently within predetermined maximum permissible errors, it has been calibrated properly and that the calibration cannot be changed. Some LFT standards include NTEP certification (US), Measurement Canada Approval (Canada), OIML (International) and EC-type Approval (Europe).

Mass & Weight
Câu hỏi:
Mass & Weight
Trả lời:

Weight is the force caused by a body's mass as affected by local gravity, such that Force = Mass * Gravity. Mass is the fundamental characteristic of a body which causes it to exhibit inertia; the quantity of material in a body, as differentiated from its size or weight. Electronic scales measure force, which is converted into a mass value based on a conversion factor derived by calibrating the instrument. Local gravity variance (depending on location on Earth) is compensated for by calibrating the scale again or entering a Geocode (conversion factor).

Parts Counting
Câu hỏi:
Parts Counting
Trả lời:

Counting groups of a part by recording a net weight of the parts and dividing it by an Average Piece Weight (Average Piece Weight) that has been statistically derived from a representative sample of the product being weighed.

May involve additional software functionality (Average Piece Weight enhancement, Auto-Add, etc.) or may involve counting items into a container or negative counting (removing a set amount from a full container). Common applications include packaging parts, inventory control, and restocking parts bins.
