I couldn't find a search field to see if this has been answered before. Apologies if the answers are obvious.

I have just received my UMIK-1. The calibration includes the following:
"Sens Factor =-.8644dB, SERNO: 7039318"

I note that the value at 1002.579Hz is -0.0171dB (close to 0dB as expected). I also note that internal analogue gain seems to be set at 18dB as this is included in the device name. I have three questions:

1. Was this measurement produced from a 1002.579Hz source at 94dBSPL?
2. Can this value be converted to dBFS? Is there a known offset value in dB?
3. What does "Sens Factor =-.8644dB" mean? It is obviously not the offset to dBFS as we would expect maybe 20dB headroom.

Thanks in advance,
