AFF16 has a remote pressure sensor. Indeed, the measurement point is often different from the display
point. On the other hand it is often difficult to locate the sensor exactly the same place where you want
to measure.
Sound pressure can be different from the ideal measurement point and where the sensor is actually
located.
The offset adjustment is used to shift the measurement value plus or minus, and dB by dB.

In case you do not want to use the "OFFSET" function, simply set the encoder wheel to 0 (in this case
regardless of the position + or -).
