Front Panel Description

Main display: double five-digit number, used to display weighing data, instrument parameters, etc., the left is A scale, and the right is B scale.

Secondary display : thirteen English letters and numbers, used to display information such as cumulative weight, cumulative times, target value, working mode, working parameters and prompts.

Status Indicator:

� STAB (stable): When the weight of the material in the weighing hopper is stable within the range of judgment, the indicator light is on

� ZERO (zero position): When the weight of the material in the scale bucket is within the range of 0±1/4d , the indicator light is on

� UNDER (Under difference): When this light is on, it means that the quantitative value is under difference

� OVER (over tolerance): When this light is on, it means that the quantitative value is out of tolerance

� FINAL (to the amount): After the feeding is completed, the indicator light is on

¤ GRIP (pocket grip): When this light is on, it means the bag grip signal output is valid

¤ SP1 (big throw): When this light is on, it means that the big throw signal output is valid

¤ SP2 (CDI): When this light is on, it means the CPI signal output is valid

¤ SP3 (Small throw): When this light is on, it means that the small throw signal output is valid

¤ DISCH (discharging): When the light is on, it means that the discharging signal output is valid
