The areas of the status view and what they mean
The following table lists the individual areas of the status view and the information they contain:
Area Meaning
Process Displays a list of individual processes during the analysis procedure. The current
process is highlighted with a colored background so that you can see the
progress of the analysis of the current sample straight away. Displays "Standby"
when the instrument is in idle mode.
Detector Displays the following current values of the detector unit:
 the current height of the current measuring peak.
 the detector temperature.
Temperatures Displays the current temperatures of the following units:
 Combustion tube
 Post combustion tube
 Reduction tube
Flow The current gas flow is displayed here.
 MFC CO2: CO
2
flow through the MFC in the TCD
 MFC O2: O
2
flow through the analysis apparatus during the combustion
 Flow CO2: CO
2
flow through the analysis apparatus
In addition to the numeric data, the gas flow is also displayed in bar chart form.
Pressure Displays the current pressure values in the instrument here:
 Input: Pressure value at the entrance section
 Output: Pressure value at the exit section
In addition to the numeric data, the pressure is also displayed in bar chart form.
Maintenance Maintenance intervals for the analyzer are defined on the basis of the maximum
number of measured samples until a certain maintenance event occurs, see
Defining maintenance intervals in the software (on page 170). The
"Maintenance" section displays the current percentage of the specified number of
samples until the next maintenance interval. This figure is displayed numerically
and as a bar chart. The colors of the chart indicates the progress of the the next
due maintenance interval.
 green: less than 80%
 yellow: 80 to 99%
 red: more than 99%
When a maintenance interval is due, its name is displayed as text on the bar chart
and a symbol flashes drawing the user's attention to this issue.
