Value for Maximum integer  

Sets for what net weight (object 0x6403) the integer net value (object 0x6401 subindex 1) rise 
the +30000 value. (floating point 32 bit format). 

Value for Minimum integer  

Sets for what net weight (object 0x6403) the integer net value (object 0x6401 subindex 1) rise 
the zero value. (floating point 32 bit format). 

Threshold value 

If the net  weight exceeds the threshold  value set and the  weight is stable, the digital output (if 
subindex  digital  out  mode=1)  is  closed  or  opened  (depending  subindex  digital  output  logic) 
(floating point 32 bit format). 

Delta weight 

Weight variation in t

echnical units accepted for the condition of “stable weight” (floating point 32 

bit format) 

Delta time 

Time in units of 100 ms used with delta weight to establish whether or not the weight is stable 
[s/10]. 

ADC speed 

The ADC speed and the frequency rejection can be customized by the table:

Hysteresis 

The  hysteresis  can  be  used  to  stabilize  the  input  value.  If  the  hysteresis  is  activated  the 
resolution is limited to ±30000 points. If hysteresis is disabled, the resolution available is the full 
24 bit ADC. 

0x00=hysteresis disabled 

0x80=hysteresis enabled
