REAL CALIBRATION (WITH SAMPLE WEIGHTS) 

 

After  having  performed  the  THEORETICAL  CALIBRATION  and  TARE  WEIGHT  ZERO 

SETTING, this function allows correct calibration to be done using sample weights of known 

value and, if necessary,  any deviations of the indicated value from the correct value to be 

corrected. 

 

Load  onto  the  weighing  system  a  sample  weight,  which  must  be 

at  least  50%

  of  the  maximum 

quantity to be weighed.

 

By  confirming  the  message 



  the  flashing  value  of  the  weight  currently  on  the  system  is 

displayed. In this phase all of the LEDs are off. Adjust the value on display by using the arrow keys if 

necessary. After confirming, the new set weight will appear with all the LEDs flashing.

 

After an additional confirmation, the message 



 will be restored and by repeatedly pressing 

the key ESC the weight will once again be displayed.

 

 

Example

:  for  a  system  of  maximum  capacity 1000 kg  and  1 kg  division,  two  sample  weights  are 

available, one of 500 kg and the other one of 300 kg. Load both weights onto the system and correct 

the indicated weight to 800. Now remove the 300 kg weight, the system must show 500; remove the 

500 kg  weight,  too;  the  system  must  read  zero.  If  this  does  not  happen,  it  means  that  there  is  a 

mechanical problem affecting the system linearity. 

 

WARNING: identify and correct any mechanical problems before repeating the procedure.

 

 

-

 

If theoretical full scale and recalculated full scale in real calibration are equal, it means 

that the theoretical calibration is currently in use; otherwise, the real calibration based 

on sample weights is in use. 

-

 

If  the  correction  made  changes  the  previous  full  scale  for  more  than  20%,  all  the 

parameters with settable weight values are reset to default values. 

 

LINEARISATION OPTION ON MAX 5 POINTS: 

It  is  possible  to  perform  a  linearisation  of  the  weight  repeating  the  above-described 

procedure  up  to  a  maximum  of  five  points,  using  five  different  sample  weights.  The 
procedure ends by pressing the 

ESC

 button or after entering the fifth value; 

at this point it will 

no longer be possible to change the calibration value, but only to perform a new real calibration. To 

perform  a  new  calibration,  should  return  to  the  weight  display  and  then  re-entering  into  the 

calibration menu.

 

By pressing ▲ after having confirmed the sample weight that has been set, the full scale appears, 
recalculated according to the value of the maximum sample weight entered and making reference to 
the cell sensitivity set in the theoretical calibration (
