This detector consists of a 120 scintillator counter array placed on the three top faces of the ALICE magnet. In order to characterize each of those detectors, an automatic system has been implemented, consisting of three main elements: a custom-made PCI electronics card, a standard high voltage power supply, and an automatic control program, running in a PC computer. The control system has been developed within the Lab VIEW framework. The whole characterization system reaches the plateau, detector efficiency and the attenuation length of a scintillator counter in about 20 minutes.]]></p></abstract>
