By analyzing the large-angle Bhabha scattering events e(+)e(-) -> (gamma)e(+)e(-) and diphoton events e(+)e(-) -> (gamma)gamma gamma for the data sets collected at center-of-mass (c.m.) energies between 2.2324 and 4.5900 GeV (131 energy points in total) with the upgraded Beijing Spectrometer (BESIII) at the Beijing Electron-Positron Collider (BEPCII), the integrated luminosities have been measured at the different c.m. energies, individually. The results are important inputs for the R value and J/Psi resonance parameter measurements.
