6.1 Function check
#
Warning!
• Check that all connections are secure. In particular, ensure that all hose connections are secure,
so that no leaks occur.
• Ensure that the power supply voltage corresponds to the voltage specified on the nameplate!
6.2 Switch-on
6.2.1 Dry commissioning
!
Note!
• If possible, let the analyser warm up in standby mode before commissioning ("Auto measuring"
display). The time can be defined via the "1st measurement" option in the PARAMETER ENTRY
menu.
• At the start of measurement with a cold analyser, the first measuring results will be errored. The
reaction is temperature-dependent and if the temperature is too low the pre-defined reaction time
is insufficient for a complete reaction. For this reason, never carry out calibration with a cold
analyser. Wait at least two hours before carrying out calibration.
When the analyser has been configured and calibrated, the measuring cycle starts automatically.
Entering parameters is no longer necessary.
To perform initial start-up or to readjust the device parameters, proceed as follows:
1. Plug-in the plug into a socket.
2. Press the
H
key until AUTO MEASURING is displayed.
3. Select the CONFIGURATION menu and program the individual options up to and including
the "Current date/time". With
H
you can return to the main menu.
4. Now complete the PARAMETER ENTRY and SERVICE menus.
With
H
you can return to the main menu.
5. Select CONFIGURATION again and use
F
to go to the "Calibrate offset" option.
6. Connect a vessel containing distilled water to the "Sample" connection and start the frequency
offset (
J
key). The registered value is displayed and saved.
7. Then reconnect the sampling line.
With
H
you can return to the main menu.
The analyser starts the "Calibration", "Measurement", and "Flushing" procedures automatically
(triggered by control signal or integrated timer) in accordance with the device parameters that you
have set (1st calibration, 1st measurement, 1st flushing times and the respective intervals control
the temporal procedure).
6.2.2 Wet commissioning
This is different to the dry commissioning in that, for wet commissioning the reagent lines are filled
before the automatic measurement, calibration and flushing cycle is started.
Proceed as follows:
1. Plug-in the plug into a socket.
2. Press the
H
key until AUTO MEASURING is displayed.
3. Select the SERVICE menu.
