How to know the value rpm
Your question is too wide. Please explain what is happening on your screenshot and what kind of an assistance you require.
maybe the screenshot shows the RPM as [3] 9 01 (hex) = 2305 (dec)
or
39 01 (hex) = 14 593 (dec) / 10 = 1459.3 RPM
You need a little more imagination and attention and you will find everything yourself. )))
