Tare
Packing material Weight of commodity that is the weight of transport package.
For example, GNweight value is the weight of car before weighing which turn to 0 after SeekTare
breakover by uprising edge, and Tareweight replace the GNweight value before.
Weighing after loading with cargo, the GNweight value is net weight. Which means GNWeight is
rough weight without tare and become net weight with tare.
First calibration
It is electricity signal that the module receive from sensor, which is not corresponding to weight
without calibration.
For example, put a 1000g weight on the weighing machine, the actual value of GNweight will set
by first calibration. If you put 1000g weight and set FirCalweight 2000(200g), the GNweight will
turn every object weighing 1000g into 200g. So the first calibration is very important.
4. Weight_Extend
Call it by SM0.0 only when expansion mode (mode=1), to do second calibration, presetting tare,
setting digital steps and starting zero tracing.
Pause time
Pause monitor can be used to identify when the weighing machine would stay at a balance
status as well as the static operation (mainly zero sample and tarring). If the change of weight is
less than specified deviation range (pause value) in a required time (pause time), then the
weighing machine is sure paused.
Digital step
Define digital step as 1, 2, 5, 10 or 20.
Zero tracing
Zero tracing can be used to eradicate zero drift after long time using scale, which will be effective
after breakover.
With this function, when the absolute value of rough weight/net weight is less than threshold for a
while, write the current analog value after filtering into zero one and save the former analog, the
output of rough weight/net weight is 0.
The origin zero analog will be written back after cancel this function. The maximum range for
zero tracing is 10d (d is digital step), the overrange value is invalid.
Preset tare
TareInput is input tare which shows value of Tareweight after TarePreset breakover by uprising
edge with a written tare value. Tare value turns to 0 after DeleteTare breakover.
For example, TareInput value set as 500 without anything on weighing machine. The TareWeight
becomes 500 after breakover of TareInput instruction, the GNweight becomes -500 along with
TareWeight turns 0 after deleting theDeleteTare instruction.
