I use a UMIK-1 to calibrate the decibel meter.
After entering a number, the app displays it as the calibration offset. If I want to then adjust it, the next value entered is ADDED to the existing offset, rather than replacing it.
If I want to zero the modification, a (-) of the current calibration offset must be entered. Entering 0, adds 0 to the existing value, which obviously has no effect.
Is this the intended behavior?
