HML4-F1 FLOW RATE VISUALIZATION The instrument can show a 5 digit character display for flow rate units; this mean the maximum flow rate value that can be represented on the display is 99999 (no matter the positioning of the decimal point). The minimum is 0.0025. The representable measure unit depends from sensor flow rate and diameter; the permitted units are those, set the instrument full scale value, allow to be represented with a numerical field which the maximum value do not exceed 99999.
HML4-F1 ACCESS TO THE CONFIGURATION MENU The converter configuration menu can be accessed ONLY using ISOCON interface (cable and software needed). ISOCON INTERFACE Isocon is a Windows® software that allows to set all the converter functions and personalize the menu (IF2X is required), see suitable manual for details.
