2.  Press and hold the TARE key approx. 10 seconds until [

Factory Reset?

appears. 

3.  Press MODE key until [

Linear auto ?

] appears. 

4. Press 

 

key to start the automatic linearity adjustment. The display appears 

the first linearity point, e.g. [

L1  2000.0g  ?

]. 

5. Confirm 

with 

 

key or press the MODE key to select another linearity point, 

which is outside the permissible tolerances, e.g. [

L2  5000.0g  ?

] and confirm with 

 

key. The display appears [

Place Lin Weight

]. 

6.  Place the required weight on the centre of the weighing pan and wait until you will 

get a stable weighing result.

8. 

Switch off the balance by pressing the ON/OFF-key.

 

9. 

Now plug off the power supply and plug in again.

 

 
Please notice the linearity points were defined and configured in our production line. 
Therefore it is not possible to change them afterwards without special configuration 
software. 
 

7.5 Manual Linearity Adjustment 

 

1.  Turn ON the balance. After warming-up time and adjustment check balance 

readings in all measuring points. In case of differences make a note. 

2.  Press and hold the TARE key approx. 10 seconds until [

Factory Reset?

appears. 

3.  Press MODE key until [

Linear man ?

] appears. 

4. Press 

 

key to start the manual linearity adjustment. The display appears the 

first linearity point, e.g. [

L  2000.0g  +00d

]. 

5.  With the arrow keys 

 

and

 

 

you can change the stored value. 

6.  Press the MODE key to select another linearity point, which is outside the 

permissible tolerances, e.g. [

L  5000.0g  -07d

] and inscribe the correction value 

like described above in point (5.) and so on. 

7.  To return to normal weighing mode press TARE key once. 
8. 

Switch off the balance by pressing the ON/OFF-key.

 

9. 

Now plug off the power supply and plug in again.

 

 

Information

If there is a positive difference (e.g. 2000.6 g = + 6 digit) you should subtract this difference 
to the stored value (e.g. [L  2000.0  -06d]). 

 

If there is a negative difference (e.g. 1999.4 g = - 6 digit) you should add this difference to 
the stored value (e.g. [L 2000.0  +06d]).
