As a part of the spin-physics program at the Thomas Jefferson National Accelerator Facility (JLab), a Møller polarimeter has been developed to measure the polarization of electron beam of energies between 0.8 and 6.0 GeV. A unique design of this polarimeter was developed. A set of three quadrupole magnets provides an angular selection of the Møller electron pairs and a dipole magnet provides energy analysis. The test procedure and commissioning of the polarimeter are presented. The results of beam polarization measurements in long-term physical experiments, the correlation for the three-beam accelerator mode and other effects are discussed.
