Diode testing uses the symbol that shows an arrow directing toward a vertical bar—the classic diode symbol representing current flow from anode to cathode. The symbol with the arrow pointing toward a line matches that diode symbol, so it indicates diode testing. The other symbols don’t depict a diode, so they correspond to different measurement modes.
