Description
Display
The “clear memory” button will delete all current data from the plots (memory). The data
in the measurement file will remain.
If measurements are acquired simultaneously for multiple ZMOD4510 gas sensors, the
measurement results file can contain data from different sensors. In the “Sensor” drop-
down menu, the user can choose a sensor to display by selecting the unique sensor
identification number.
The drop-down menu adjacent to the “show” button provides options for selecting the
time period for showing the recent history or the complete data. Click the “show” button
to apply new settings to the plots.
Algorithm Result
The first 10 measurements of the algorithm will be taken for sensor stabilization. During
this time, the “Algorithm Result” section will indicate the completion progress. Note that
this does not cover the full stabilization of the sensor module. Recommendation: The
ZMOD4510 has a sample time of 1 minute for these 10 measurements resulting in 10
minutes for the initialization measurements.
After the stabilization measurements, the “Air Quality Index” (AQI) is shown in six
categories:
0 to 50 Good Air Quality
51 to 100 Moderate Air Quality
101 to 150 Unhealthy Air Quality for Sensitive Groups
151 to 200 Unhealthy Air Quality
201 to 300 Very Unhealthy Air Quality
> 300 Hazardous Air Quality

The lower half of the display provides a visualization of the data. This plot shows the AQI based on the standard of the US Environmental
Protection Agency (EPA). For additional information, including application notes, white papers and blogs, visit
