  The LHC in­jec­tors Up­grade (LIU) pro­gram has been fully im­ple­mented dur­ing the sec­ond long shut­down (LS2), which took place in 2019-20. In this con­text, new or up­graded beam in­stru­men­ta­tion was de­vel­oped to cope with H beam in LINAC4 and the new Pro­ton Syn­chro­tron Booster (PSB) in­jec­tion sys­tems which would pro­vide high bright­ness pro­ton beams in the rest of the in­jec­tor com­plex. After a short overview of the newly in­stalled di­ag­nos­tics, the main focus of this paper will move to the in­stru­ments al­ready com­mis­sioned with the beam. This will in­clude LINAC4 di­ag­nos­tics, the PSB H0/H mon­i­tor, the PSB Tra­jec­tory Mea­sure­ment Sys­tem, and the PS beam gas ion­iza­tion mon­i­tor. In ad­di­tion, par­tic­u­lar em­pha­sis will be given to the first op­er­a­tional ex­pe­ri­ence with the new gen­er­a­tion of fast wire scan­ners in­stalled in all in­jec­tor syn­chro­nous.
