Function Description
Input and output scaling capability. Working of the analogue outputs (y) versus input variables (x) Figure A The sign of measured quantity and output quantity remains the same. The output quantity is proportional to the measured quantity. Figure C The sign of measured quantity and output quantity remains the same. With the measured quantity being zero, the output quantity already has the value Y1 = 0.2 Y2. Live zero output.
