6. Multi-range scales

These scales have a real scale interval d which varies according to the scale range (e.g. DeltaRange, DualRange, MultiRange and PolyRange scales). To reduce the final uncertainty, each range should be considered as an individual scale.

Example of a multi-range scale:

DualRange analytical balance :

  • range 1: from 0 to 80 g, d1 = 0.01 mg

  • range 2: from 80 to 220 g, d2 = 0.1 mg

MultiRange industrial scale :

  • range 1: from 0 to 15 kg, d1 = 5 g

  • range 2: from 15 to 30 kg, d2 = 10 g

  • range 3: from 30 to 60 kg, d3 = 20 g

  • Repeatability test

    It is recommended to perform a repeatability test for each scale range.
