SYSTEM STATE, the displays of the components which are not yet ready are
shown in read during initialization. During the start
-up phase of the analyzer the
external communication with the program is blocked.
The individual components have different start
-up periods:
NDIR detector approx. 10 minutes start-up period
Furnace approx. 10 minutes heating-up time
CLD approx. 20 minutes running-in time
The measuring gas flow reaches the target value (160 ± 10 ml/min) after approx. 1 to 2
minutes.
7. If the analyzer is not ready for measurements after 30 minutes (one or several
components are still shown in red in the window S
YSTEM STATE), check the hose
connections and carry out a fault finding exercise in accordance with the notes in
section "Fault removal" p. 91.
If necessary additional commissioning tasks are required dependent on the measuring
task or after maintenance or component replacement:
8. Readjust the sampler after each syringe change and each manipulation at the locks
(e.g. catalyst replacement, maintenance) or check the adjustment (see section
"Adjust autosampler" p. 65).
9. Enter the syringe size after each syringe replacement:
• With the menu command C
ONFIGURATION EDIT OPTIONS open the window
O
PTIONS tab ANALYZER COMPONENTS.
• In the list field S
YRINGE SIZE select the syringe volume.
10. If necessary, adjust the NPOC purging flow (see section "Adjust the NPOC purging
flow" p. 68).
Note:
The NPOC purging flow has been preconfigured to approx. 100 ml/min. This flow is
suitable both for measurements with the autosampler and for measurements with
manual sample supply. The NPOC purging flow can be increased or reduced dependent
on the measuring task.
6.3 Carrying out the calibration
6.3.1 Preparing and starting the calibration
The control and analysis software multiWin provides the option to adjust the analysis
individually to the measuring task by selecting the methods. An ideal measurement with
its corresponding method requires its own calibration for each analysis parameter and
each measuring channel. Not all parameters need necessarily be calibrated.
Three calibration functions can be stored for each parameter in a method.
