Knowledge Output/Display screen: At the end of the measurement period, the data might be downloaded within the dosimeter to a computer for Evaluation. Some dosimeters also contain a Exhibit to deliver real-time noise publicity info.
Most sound level meters have a clear digital Liquid crystal display, generally backlit to allow for Operating in small-mild predicaments. It’s truly worth taking a second to look at the purpose buttons to check out if their intent is obvious and they’re easy to work.
