This paper describes a tester for automated testing of power quality analyzers, focuses on evaluation of correct gapless and non-overlapping measurement according to standard IEC 62586-2[1]. A test is used in order to verify the accuracy of the basic time window for evaluating RMS voltage values (10/12 cycle), and to evaluate whether during the measurements RMS samples (gapless) are not lost and mutual overlaps of individual cycles are not produced. The tester is based on principles of virtual instrumentation. The testing hardware uses PXI system architecture and the software is made in NI LabVIEW programming environment.
