3.3. Multi-interval instruments
Instruments with one weighing range may have several partial weighing ranges (multi-interval instruments). Multi-interval instruments shall not be equipped with an auxiliary indicating device. Each partial weighing range i of multi-interval instruments is defined by: — its verification scale interval e_(i) with e_((i + 1)) > e_(i) — its maximum capacity Max_(i) with Max_(r) = Max — its minimum capacity Min_(i) with Min_(i) = Max _((i – 1)) and Min_(1) = Min where: i= 1, 2, … r, i= partial weighing range number, r= the total number of partial weighing ranges. All capacities are capacities of net load, irrespective of the value of any tare used. The partial weighing ranges are classified according to Table 2. All partial weighing ranges shall fall into the same accuracy class, that class being the instrument’s accuracy class. Table 2 For i = r, the corresponding column of Table 1 applies, with e replaced by e_(r.) Multi-interval instruments i= 1, 2, … r i= partial weighing range number r= total number of partial weighing ranges Class Verification scale interval (e) Minimum capacity (Min) Number of verification scale intervals Minimum value Minimum value n((Max_(i))(e_((i 1)))) Maximum value n((Max_(i))(e_(i))) I 0,001 g ≤ e_(i) 100 e_(1) 50000 — II 0,001 g ≤ e_(i) ≤ 0,05 g 20 e_(1) 5000 100000 0,1 g ≤ e_(i) 50 e_(1) 5000 100000 III 0,1 g ≤ e_(i) 20 e_(1) 500 10000 IIII 5g ≤ e_(i) 10 e_(1) 50 1000
