Subtracting scale is to control the material (i.e. the material feed) weight discharged by the
control hopper. Please refer to Fig 6-2 for the function and the meaning of setting parameters
during the process and the sequence order for controlling the input and output:
Figure 6-2 Working Sequence Drawing of Subtracting Quantitative Scale
The parameter instruction in the Figure：t0：Measurement delay of material feed，t1：Quick feed over delay，
t2： Slow feed over delay（The instrument during the three periods will not judge the weight）；d1：Quantitative
value of feed；q1：Quick feed lead of material 1; a1：Slow feed lead of material；o1： Allowance of material ；
b2:Min. remaining weight of material; A2:Charging weight of material
Note to working process of subtracting quantitative scale:
1. The Add Signal is needed before material feeding;
2. The Discharge Signal is needed during material discharging;
3. If the Add Signal and Discharge Signal are always valid, the indicator will automatically
