Configuration
The instrument arrives from the factory configured
and ready to operate as a conductivity transmitter.
This section provides detailed procedures for chang-
ing operation values for specific applications.
Activate with

Mode code “1200”
During configuration the Transmitter
is in the Hold state, the loop current
is frozen.
When the configuration mode is exited, the Transmit-
ter remains in the Hold state for safety reasons. This
prevents undesirable reactions of the connected pe-
ripherals (e.g. limit switches, controllers) due to in-
correct settings. The measured value and Hold are
displayed alternately. Now you can check whether
the measured value is plausible and specifically end
the Hold state with
ENTER
. After a relax time of
20 sec (for measured value stabilization) the Trans-
mitter returns to measuring mode.
The configuration parameters are
checked during the input. In the
case of an incorrect input “ERR” is
displayed for 3 sec. The parame-
ters cannot be stored with
ENTER
until the input has been repeated.
