Q. Hi
can I measure over a day or week with this recorder and view the results in a graph on my p.c ?
A. Hi Steve, thank you for your question. The meter has memory for 32000 measurements, which can be transferred to your PC and processed using the software supplied. You can therefore easily monitor sound levels on a long-term basis. The time that the memory lasts will depend on the settings that control the frequency that it takes a reading.
