2.1 Software Modes
2.1.1 “Measurement” Tab
Click on the “Measurement” tab to display the measurement options. On this tab, the user can see the properties of the ZMOD4410’s gas
measurements, which includes setting the temperature in °C and changing the sample time in seconds used during the gas measurements.
The sampling rate in Standard Operation is fixed at 2 seconds, while in Low Power Operation it is fixed to 6 seconds. In Odor Operation, the
sample rate can be changed between 1 and 15 seconds.
When the “start sensor” button is clicked, the measurement starts running continuously with the interval selected under “Sample time” via the
up/down arrows. The results will be automatically added to the plots in the “Analysis” tab and continuously saved in a comma separated file
(CSV), which is user-selected via the file selection dialog accessed by clicking the “…” button adjacent to the “Append to data file” field, which
displays the selected path and file name.
A comment (for example, “Apply test gas”) can be added to the data entry by adding a string to the “Add comment to next measurement” field
and then clicking the “ok” button. If a measurement is already in progress, the comment will be added to the next measurement. If a comment
is on hold waiting for the next measurement, it can be deleted by clicking the “clr” button. The comments will be displayed in the plot shown on
the “Analysis” tab and will be saved in the CSV result file. This facilitates tracking the user’s experimental investigations.
2.1.2 “Analysis” Tab
Depending in the operation mode (“Standard”, “Low Power”, or “Odor”) the user will see slightly different screen.
For Standard Operation and Low Power Operation
Click on the tab to display the “Analysis” tab (see Figure 5). The “Analysis” tab shows three plots:

IAQ rating according to the standards of the German Federal Environmental Agency (UBA).

eCO

concentration (in ppm)

Raw sensor signal (in Ω)
For more information on IAQ and eCO

, refer to the ZMOD4410 White Paper – Overview of TVOC and Indoor Air Quality and the ZMOD4410
Application Note – Estimating Carbon Dioxide.
There are
four sections for user interaction located above the graphs:
