Pls help reading gauge…

Is it true the compressor gauge is more accurate???

Compressor stop needle is a bit before 3000psi I assume it’s psi so I filled my pp700sa the machine stoped but the Pistol gauge shows 18 X10 bar??? Almost 200bar

omg im so dumb 3000psi equals 206 bar

so i need to put more air in the pistol is this correct to get it to 220bar right beside the red on pistol gauge.
