Q. I programmed the analog output of my UDM35 meter to retransmit as 4 to 20 mA the displayed pressure range (0 to     18 bar). The parameters I set are Lo.A=4 and Hi.A=20 but the output signal is completely wrong. What is the
    problem?


The parameters Lo.A and Hi.A represent the Analog signal corresponding respectively with the Lo.d and Hi.d displayed values. These parameters are set as a percentage of the Analog output full scale value (20mA or 10 VDC according to the TYPE selection). Therefore, to set 4 mA, the right value of Lo.A is 20 (20% of 20mA is 4 mA) while Hi.A must be 100 (100% is 20 mA). Note that a reverse Analog output characteristic is possible by setting Lo.A greater Hi.A.
