Compression test...What cranking RPM for accurate reading???

I have everything off car. But This turbo does not crank as fast as my N/A did. Its kinda slow. Can I still get accurate readings? I will be using the more expensive mazda checker. Thanks

See Chapter 1 of the Factory Service Manual for the correct compression check procedure and for cranking speed & altitude compensation charts.

Hm ok the Mazda Compression Checker that I did before on another car didnt use 10-150psi to show compression it used 1-10 or whatever. Last time I got a 3.5 2.6 7.0 on a bad engine. Is this X10 ???
