Please help calibrate CALBK

Good afternoon, a tragedy happened, I accidentally made FRU default settings and all the settings of the pneumatic unit disappeared.I can't calibrate the Block And Pressure Zeros item, it's just a countdown and a Failed Test-Discarded error, and I don't know what to do or open / close to pass this calibration, I beg if someone knows how to do this calibration write me Dlinniyalex@gmail.com
