The DIP switch must be in ON position. Then do the scaling of analog inout value. P0757[0] = 4 ( lowest 'mA' fed from Pressure Transmitter) P0758[0] = 0 ( scaling the lowest value to 0% ) P0759[0] = 20 ( highest 'mA' fed from PT ) P0760[0] = 100 (scaling the highest limit to 100% ) Now your input 4 - 20 mA input is scaled to 0-100% (your PT should give 4mA as output when your pressure is at 0 bar and 20 mA as output when it reaches 15 bar). And you can see in parameter r0754[0] {read-only} what is the scaled value according to your input analog signal. rgds, RBM
