From the Aeroqual Cloud home screen, click Manage Data.

From the list of menus on the left-hand side, select Insights

Note that Insights is only available for data sampled by Ranger instruments

A chart is populated with raw PM values, 8-hour Time-Weighted-Averages, and OSHA/ACIGH limits

The OSHA limits are populated using PARTICULATES NOT OTHERWISE REGULATED, TOTAL AND RESPIRABLE DUST (PNOR)

The ACIGH limits are populated using Particles (insoluble or poorly soluble) Not Otherwise Specified (PNOS) from the 2022 TLVs and BEIs

To hide a series from the chart, click on the series name above the chart

To unhide a series, click on the series name above the chart once more

Raw data averaging will not occur while the Averaging Period displays "Unfiltered Data"

8-hour time-weighted-averages (TWA) are calculated by summing all minute-by-minute samples taken between "From" and x-axis dates/times, and dividing the sum by 480 minutes

Take note wherever the 8-hour TWA exceeds a corresponding exposure limit

A table appears on the right, summarizing the highest 8-hour TWA reached during the sampling period between "From" and "To" dates/times

To visualize key data, hover your cursor above any 8-hour TWA value in the table

The chart will hide all series except those that correspond to the value

If any 8-hour TWA exceeds one or more corresponding limits, the cell will be colored red

If any 8-hour TWA exceeds 50% of one or more corresponding limits, the cell will be colored yellow

To adjust the dates and times for which you wish to plot data, edit the value in the "From" and/or "To" fields

Then click "Update"

The chart and table are now updated using only data sampled in the period between the "From" and "To" dates/times

The 8-hour TWA's have been re-calculated
