1. INTENDED USE - MAIN FUNCTIONSScales series WTC /LW are designed for counting pieces with same unitmass. Counting process can be realized as: Specification of sample mass (one piece) Calculation of sample mass from some determined amount ofsamples on the weighing panTARE functions allows for determination of net mass of measured loads – tarerange equal to max capacity of the instrument – Max.Functional possibilities− Setting alarm function for counting (threshold)− Change of scale readability− Totalizing in counting pieces mode− Counting pieces2.
