What does tuner 'Tuning range B0 – B7. A4 Calibration' mean?

It was noted on a guitar tuner

A0 is the lowest note on a piano. B0 would be 2 notes above that. A7 is at the other extreme below the high C [C-8]. B7 is one note below the high C. The numbers relate to octaves. IOW, middle C is called C4, one octave lower would be C3 etc.

The range of a double 10 standard tuned pedal steel guitar is about A1 to A6, I believe.

A4 is the A just above middle C. Frequency wise, a reading or calibration of 440 Hz. is generally considered standard. That is the most commonly used central frequency for tuning modern instruments, although many tuners can be calibrated anywhere between A 435 to A 445 or perhaps even a broader range.

So, your B0 to B7 tuner can read and tune both high and low frequency notes within the rated range relative to the base frequency of A calibrated to 440 Hz.

Maybe a keyboard diagram will explain it better. http://www.harmoniumnet.nl/klavier-keyboard-ENG.html

middle C is called C4, one octave lower would be C5 etc.

Wouldn't that be C3?

I knew it just had to be momentary brain fade.

Too much turkey yesterday? That will do it.
