INPUTS FUNCTIONING : 

Each  input  can  work  in  positive  or  negative  logic  individually.  A  debounce  time  attached  to  both  inputs 
can be adjusted. 

6.1  Inputs assignement :

suspend current cycle 

 

 

 

 

6.2  Functions independant of the functioning mode : 

none : Inputs have no effect. 

 

-  tare :  one  or  the  other  or  both  inputs  can  be  assigned  to  the  tare  function.  The  tare  acquisition  is 
conditioned by a stability criterion that can be changed or inhibited. 
Depending on the choosen logic (positive or negative), the tare is triggered by a rising or a falling edge. 

 

zero : one or the other or both inputs can be assigned to the zero function. 
A new volatile zero value is acquired only if its value is within ±10% range of the specified capacity. The 
zero acquisition is conditioned by a stability criterion that can be changed or inhibited. 
Depending on the choosen logic (positive or negative), the tare is triggered by a rising or a falling edge. 

 

6.3  Functions specific to each functioning mode : 

See corresponding sections for a complete description.
