If corners 

do

 require adjustment, complete the following steps: 

1.  Place the concentrated weight on the corner displaying the lowest weight. 

2.  Turn the adjustment on the potentiometer clockwise (

CW

) to the displayed weight 

so it reads the same as the highest reading.  

3.  Repeat this procedure while rechecking all corners until they are equal. 

Important Note: 

When moving the weight(s) from corner to corner,

 

DO NOT

 

zero the scale.

  The purpose is to adjust the corners to be the same, and not to 

perform a correct calibration. 

4.   Perform a zero reference check with an unloaded platform,  
5.  Repeat the corner test to ensure all readings are the same before proceeding. 
 

 

If ‘cornering' the platform is difficult, follow these steps. 

1.  Note which corner has the highest reading.  

 

2.  Turn all potentiometers to the full 

counter-clock-wise position 

until a 

clicking sound is heard.  

3.  Place the weight on the lowest reading corner. 

4.  Turn the corresponding potentiometer 

clock-wise

 to read the same as the 

corner with the highest reading. 

5.  Repeat each corner to match the one with the highest reading. 

 

 

 

If corners 

do not

 require adjustment, complete the following steps: 

1.  Remove all weights. 
2.  Zero the indicator. 
3.  Perform a final calibration with test weights. 
4.  Follow the appropriate indicator service manual to ensure a proper calibration.
