Hi to all
 I had made a program three years ago with the help 
of the main ixo65 with an analog sensor 4-20 ma and
 using a 500 ohm resistor in series I had connected 
it to an input of the logo 0-10 volts
 It worked very well so far but the following problem
 occurred for some reason instead of showing me calmly
 0 bar counts -0.04bar and does not workfrom 0 bar and 
above works normally How can I achieve this
 programmatically? 
Or by changing the value of the resistor in series,
 has it lost 
some ohm, I count 498 ohm with the multimeter instead
 of 500, do 
you say that this plays a role?

how can i do sir ?
