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 

 

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 8 POINTS: 
It is possible to perform a linearisation of the weight repeating the above-described procedure 
up to a maximum of eight points, using eight different sample weights. The procedure ends by 
pressing the 

 button or after entering the eighth 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 (
