Meter Test Systems

The PTS 3.3 C portable test system consists of an integrated threephase current and voltage source and a threephase electronic reference standard of accuracy class 0.05%. Characteristic features of the PTS 3.3 C are its wide measuring range, high accuracy and high tolerance to unwanted external influences.The PTS 3.3 C allows the overall testing of meters and metering installations plus analysis of the local mains conditions. Advantages ! Easy verification of meters under precise load conditions, using the built-in, compact, current and voltage source ! Automatic operation with (programmable) predefined load points without the need of an external PC ! Exchangeable Compact Flash (CF) memory card for storage of measurement results and customer data ! Display of vector diagram and phase sequence for analysis of the supply conditions ! User-friendly system for data input and easy operation of combined source and reference meter ! The system may be used either as a stand-alone reference standard meter, or together with the integrated power source as acomplete portable test system Functions ! Independent generation of single or three-phase loading conditions for verification of meters ! Active, reactive and apparent energy measurement for single phase, three phase, 3 wire or 4-wire, systems with integrated error calculator and pulse output ! Vector diagram, harmonics spectrum, wave form and rotary field display for analysis of the mains conditions !
