A / C COMPATIB.
# 121
Due to different software versions,
I/O board and amplifier board are
only partially compatible (possibly
restricted functionality).
!
Note!
– The indication on the display as
notice message appears only for 30
seconds (with listing in “Previous
system condition” function).
– This condition can occur if only one
electronics board has been
exchanged; the extended software
functionality is not available. The
previously existing software func-
tionality is still working and the
measurement possible.
Module with lower software version
has either to be actualizied by ToF Tool
- Fieldtool Package with the required
software version or the module has to
be replaced.
