is not calculated. Thus the intensity of 403 cm
If the intensity does not meet the specifications, or the energy at high wavenumbers (to 4600 cm
low, run [Auto adjustment] on the [Instrument] Menu, and reanalyze the spectrum. If the power spectrum does
not improve after the "auto adjustment", the system may be damaged; contact your SHIMADZU representative.
If the intensity remains zero, the light source may be disconnected or damaged; light source replacement or
repair should be performed by a SHIMADZU service engineer.
