If you want to calculate device value you have to fill "Formula" field, ie:

%value%*1

which of course returns value multiplied by 1 ;-).

In my case I had to calculate voltage measured by 1:2 divider and 1:3.3 divider, so my formula was:

%value%/1024*3.3*2

the value is divided by 1024 because ADC has 10 bit resolution.
