As part of my new job, I've been handed an AeroTrak particle counter and a test procedure and essentially told, "figure it out." I read the procedure, set up the meter the best I knew how (not having even seen one before), and then set up and ran the test. Now I have data, and I don't know a thing about how to interpret it. If I try to make information from the data, I get a really odd conclusion -- in one portion of the test, the data shows the air as being dirtier after the filtration run than it was right after the fire burned. I'm no expert, for sure, but this just doesn't make sense. Yesterday involved a bunch of reading regarding CADR (clean air delivery rate) testing and the "standard" setups for such tests. I understand the basics of the test, so that's a start. But I don't yet understand the results this meter is presenting. Today I wrestled with it some more, realizing that I didn't label the "recipes" well enough to be properly descriptive in the report. That, I can work around. Then tinkering with the software, I found that maybe I didn't ask for the right data (units of measure) to be presented. So I re-ran the report with different u/m and got different numbers but very similar graphs. (Reasonably so.) To the point: I'm hoping to tap the SF "guru collection" and find someone who's got knowledge of this type of test, and -- as a bonus -- someone who's familiar with this particular meter. I read some this afternoon about a similar Fluke product (925? 985? I can't remember.) and the test method was mostly similar, but very different with respect to the use of a zero-pass filter.  Hoping someone here has the knowledge, and thanking you all in advance. God bless America. | ||

Yessir, I've got the manual, thank you. I've run a couple of informal cycles in the office, and another following the procedure I was given. Where I get into trouble is in the interpretation of the data, with respect to CADR and ISO standards. The manual doesn't address that zero-pass filter at all, aside from the fact that it's in the kit. There's no mention of how or when to use it. Many of the videos are done by Indonesians... given that and interesting things in the writing of the manual, I wonder if the company is Indo and perhaps some things are either incomplete or lost in some translation. Maybe? I did have some better luck with the numbers on Thursday, though, and I'm wondering if the initial crummy data is the result of my not having understood the recipe setups well enough prior to the first test run. I believe next week will bring about a re-do of the prescribed test, and likely some rewriting/clarification of the procedure. God bless America. | |||

The closest thing my experience has is air particulate testing for radioactivity and that was just an aside since we had dedicated people for that. But I recommend a possible resource for you: https://openai.com/ Something technical like what you're looking for would be right up its alley. What I do is I sometimes ask the same question worded a different way. Or even challenge it on its answers such as "you said thig but..." Here is the second question I asked after asking about AeroTrak particle counter. I asked, "What can you tell me about AeroTrak particle counter and zero pass filter"
How do you interpret the data from an AeroTrak particle counter??
I'm thinking you can give it specific data in terms of readings and it can help you interpret it. I don't know how you feel about AI but I see it as a tool even under the construct of it being ultimately used for good or evil. Just because a tool is used by others for evil shouldn't preclude my ability to use it for good. It's the next evolutionary step in search engines. Good luck. "It did not really matter what we expected from life, but rather what life expected from us. We needed to stop asking about the meaning of life, and instead to think of ourselves as those who were being questioned by life – daily and hourly. Our answer must consist not in talk and meditation, but in right action and in right conduct. Life ultimately means taking the responsibility to find the right answer to its problems and to fulfill the tasks which it constantly sets for each individual." Viktor Frankl, Man's Search for Meaning, 1946. | |||

Maybe reach out to the insurance company that writes the Workers Compensation for your company. I know the insurance company I worked for had a dedicated group of engineers that would assist clients with that type of thing. | |||
