7.12. Potentiometer scaling

 

Function

 

When you are going to use the potentiometer with better 
resolution than 1% you can assign resistance values with 
1, 2, 3, 4 decimal resolution to the start and end position of 
the potentiometer. 
 

The figure shows the factory default settings. 

 

Sequence of operations

 

 
1. Select the number of decimals. 
2. Type-in the start resistance value (0%, upper window), 
than the end resistance value (100%, lower window). 
 
Note: 
It can be used either dot (.) or comma (,) for decimal. 
When you type in more decimals the software corrects it for 
one decimal after clicking on the “download settings” 
button.
