Programming a analog input

Thank you. This really helps alot. I'm taking fewer tylenol thank's to your help. Since my LO_LIM is now a negative. I need a positive edge(1) at the bipolar tag , correct? -3.663400 =10mvdc to 3.330000 =10vdc

No,it's not that way. You would need a positive bipolar signal if your input range was -10V to +10V. But your input signal now still is 0V to 10V. So it is not bipolar.
Your range now is:
0V --> -3.6634
10V --> +333.0

Have a nice weekend!

Hello everyone, I'm new here.
Just want to ask you, because my input signal is 4 to 20 mA. Because it's starting from 4mA, not from 0, will that something effect in the LO_LIM and HI_LIM and output signal?
Should i change something because of that?

Typically when you're scaling a 4-20mA analog input that 4mA signal being produced is going to reflect your LO_LIM. You've got an input of 4-20mA and an output from 0-x (whatever eng. units you're scaling to).
