FDO® 925 IDS - Firmware Update - V1.06
Download and installation notes:

Please note:

•It is necessary to update the firmware of the FDO® 925 as well as the firmware of the meters (separate program - see section above).
•FDO sensor update with 3420/3430 only via channel 1.
•Please carefully follow the instructions given in the Readme pdf file.

Version history – innovations

•V1.06: Minor general optimizations

•V1.05:
?The FDO®925 can be operated with an adjustable t90 response time function.
This function allows the adaptation of the response time of the FDO 925® to the application, e.g. measurement in an aeration tank, checking of online sensors.
?Optimized digital communication
