Isodata Data String - Bender ISOMETER isoCHA425HV Manual

5.4

IsoData data string

In IsoData mode the ISOMETER® sends the entire data string roughly once per 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 Adr is set to 0. In this case, the "Adr" symbol
flashes on the measured value display.
