The additional functions are device-specific. When ordering an additional
function, you therefore have to specify the serial number of your FRONT
module in addition to the respective order number.
(The FRONT module contains the device system control).
The manufacturer then supplies a TAN (transaction number) to release the
additional function.

Start End
The KI recorder follows the course of the process and releases a messages in
the event of a deviation. It is called up from the measuring mode: meas.
Continuous processes
The measured signal is surrounded by a dynamically tracked, process-
controlled tolerance band. Slight fluctuations are tolerated. If the
measured value leaves the tolerance range, a message is released (Fig.).
The recording interval can be set from 10 s to 60 h.
Batch processes
The KI recorder provides an automatic self-learning function. This allows
checking whether regularly recurring processes keep the preset tolerances.
Deviations from the normal course of process (plus preset tolerances) gener-
ate a message (Fig.). Maximum process duration can be set from 1 to 60 h.

The parameters are stored in the tolerance band recorder (Diagnostics

within their tolerance bands, the new data are not stored.
Drift due to aging or calibration scatter can be identified at a glance,
thus allowing to draw conclusions as to electrode life and the required

Concentration determination
The substance concentrations in percent by weight (% by wt) for H2SO4,
HNO3, HCl, NaOH, NaCl are determined from the measured conductivity
and temperature values.
Conditions for concentration determination
Below you find tables with the concentration ranges of the preset substances.
These tables show the conductivity of the substances versus substance concen-
tration and process temperature.
The following conditions must be met for a reliable concentration determina-
tion:
For calculation of concentration, the medium to be measured must be a
purely binary mixture (e.g. water-hydrochloric acid). Presence of other
dissolved substances (e.g. salts) leads to incorrect concentration values.
In the region of small slopes (e.g. at the range limits) small conductivity
changes can correspond to great concentration changes. This may lead to an
unsteady display of the concentration value.
As the concentration value is calculated from the measured conductivity
and temperature values, accurate temperature measurement is very
important. Therefore, you should make sure that sensor and process
medium are in thermal equilibrium.
Messages
You can define limits for warning and failure messages for the concentration
value:
