MENU/ENTER:  to enter a menu/confirm the data entry. 

:        to modify the displayed figure or menu item. 
:        to select a new figure or modify the displayed menu item. 

ESC:        to cancel and return to the previous menu. 

 

 

THEORETICAL CALIBRATION 

 

This function allows the load cell rated values to be set. 

 

To perform the theoretical calibration set the following parameters in sequence: 

-

 



 (default: 



)

the 

system full scale 

is given by one cell capacity multiplied by the 

number  of  cells  used.  Example:  4  cells  of  1000 kg 

  FULL  SCALE = 1000 x 4 = 4000. 

The instrument is supplied with a theoretical full scale value 



 corresponding to 10000. To 

restore factory values, set 0 as full scale. 

-

 



 (default: 2.00000 mV/V):

 sensitivity

 is a load cell rated parameter expressed in mV/V. 

Set the average sensitivity value indicated on the load cells. It’s possible to set a value between 
0.50000  and  7.00000 mV/V.  Example  of  4-cell  system  with  sensitivity:  2.00100,  2.00150, 

2.00200, 2.00250; enter 2.00175, calculated as (2.00100 + 2.00150 + 2.00200 + 2.00250) / 4. 

-

 



:

  the 

division

  (resolution)  is  the  minimum  weight  increment  value  which  can  be 

displayed. It is automatically calculated by the system according to the performed calibration, so 

that it is equal to 1/10000 of full scale. It can be changed and be variable between 0.0001 and 

100 with x1 x2 x5 x10 increments.

 

 

-

 

By  modifying  the  full  scale  or  the  sensitivity,  the  real  calibration  is  cancelled  and  the 

theoretical calibration only is considered valid. 

-

 

If the theoretical full scale and the recalculated full scale in real calibration (see section 

REAL  CALIBRATION  (WITH  SAMPLE  WEIGHTS)

)  are  equal,  this  means  that  the 

calibration currently in use is theoretical; if they are different, the calibration in use is the 

real calibration based on sample weights. 

-

 

By  modifying  the  theoretical  full  scale,  the  system’s  parameters  containing  a  weight 

value will be set to default values (setpoint, hysteresis, etc.).
