9. IsoData data string
In IsoData mode, the ISOMETER® continuosly sends the whole data string with a cycle
time of approximately 1 second. Communication with the ISOMETER® within this mode
is not possible and no additional sender may be connected via the RS-485 bus cable.
IsoData is activated in the menu "out", menu item "Adr" when it has been set to Adr = 0.
In this event, the symbol "Adr" flashes on the measuring value display.
