The following settings can be changed via the

Setting
Description
ppb limit (ppb)
This limit indicates the maximum value at which the output signal for the detection limit
value is switched. The maximum value for scaling the 4-20 mA outputs is also indicated
here. The displayed value therefore corresponds to 20 mA.
Rinse
qualification
(sec)
This value indicates the rinse time (in seconds) during which a sample is introduced during
an SST or calibration (recommended value: 300 seconds).
Rinse
measurement
(sec)
This value indicates the rinse time (in seconds) during which a sample is introduced at the
start of a measurement (recommended value: 300 seconds).
Standard (ppb)
This value can be used to define the TOC value to be used as the default value for a
calibration (recommended value: 1000 ppb).
Repetition
This value indicates the number of repetitions to be performed during an SST or a calibration
(recommended value: 5 repetitions).
Interval List
The interval mode editor can be opened via this key (option) → 32
It is possible to enable or disable the following hardware parts via the

Description
Trigger input
[ON/OFF]
The trigger input is enabled with this option. The trigger input ensures that the system can
be started and stopped by an external contact. The analyzer remains active as long as the
contact is closed (order option).
Pressure sensor The analyzer can monitor the pressure of the selected input with the pressure sensor. If a
vacuum is detected, the measurement is stopped. If a sufficient sample pressure is detected
afterwards, the measurement can be resumed (with the
Continue after error
function
switched on). The limit values used can be configured in the
Service 1
tab (available for order
option "Detection inlet pressure sample").
Leakage sensor
The leak sensor is switched on and off with this option.
UV sensor
The sensor installed in the UV reactor is switched on and off with this option.
Calibr. single
port
If a standard analyzer is used or if the corresponding ports for SST and calibration are not
available due to the set interval mode, this option can be used to force qualification at one
port only (input 1). Processing of the qualification is then sequential and at the operator's
request.
Continue after
error
If an error occurs during the measurement, the active measurement is interrupted. Once the
error has been rectified (e.g. vacuum in the measuring line), the measurement can resume
automatically with this option. The device is rinsed again beforehand.
Show
compensated
cond.
The conductivity value in the measurement view can be changed from temperature-
compensated values to uncompensated values.
The following parameters can be set in the
Service 1
tab:
Setting
Description
Temperature-
Offset C1 [°C]
This value indicates the offset for temperature sensor C1.
Temperature-
Offset C2 [°C]
This value indicates the offset for temperature sensor C2.
Temperature
limit [°C]
This value indicates the temperature limit; if this limit is exceeded a warning is generated.
Fast pump
speed
This value indicates the speed at which the rinsing is performed.
