The input signal is digitalised, analysed and shown in the LC display. Fault signal No measured value seen in the LC display, no rear illumination. HART protocol The display allows transmission of the HART® protocol signal. Power supply Electrical connection See chapter 5 Supply Using the 4 to 20 mA current loop Volt drop < 2.5 Volt Accuracy Current Measurement error < 0.1 % FSD Temperature drift: 0.01 % / K ambient temperature 21
