CANNOT LINEARIZE NEGATIVE NUMBERS IN URA-0800T

hello everyone. I need help. I have a URA-0800T to linearize dew point from -100 to +23 degrees celsius. but the linearizer block only allows me to put UINT16 type tags on input A, and I cannot put INT16 type y1 and 2.
can anybody help me? Thanks in advance.

hi

i think that the "problem" is that you select the input chanel of the URA-0800T analog reader module...this can has only UITN16 range and not negative value...linearization LFB is needed to conver the UINT16 range in the INT16 range...for example 4 mA (positive value) input means -100 (negative value) and 20 mA (always positive) means +23 (positive)...hope that is correct and clear.
