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 CONF
CONF change parameter with Y and ",
confirm/continue with ENTER,
end with CONF.
Mode code "1200"
During configuration the Transmitter
is in the Hold state, the loop current
is frozen.
Before attempting any changes refer to the parameter setup list shown below. This table presents the possible options and the factory settings.
Process variable / meas. range
Selected process variable and
measuring range control loop cur-
rent, limit values and display.
Complete configuration required
after change.
Concentration
(only with %)
Temperature display
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.
