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®
in 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 dis-
play.
