Tuning

 

a change—within limits determined by specifications —of the variables of instruments, machines, or devices, usually during operation, upon shifting to a new operating mode (distinguished from adjustment, which is aimed at ensuring normal functioning). If necessary, tuning may be done under conditions more stringent than normal operation to verify the operational capacity of the least reliable and most important elements of the apparatus. The results of tuning are frequently recorded and formalized in appropriate technical documentation (technical certificate, test report, or acceptance certificate) upon completion of manufacture or delivery to the user.

The term “tuning” frequently means regulation of the tone of musical instruments, finding the desired wavelength on the scale of a radio receiver or transmitter, or selection of television broadcast channels.
