Introduction

The PC02 Phase Checker allows fast testing of the polarity of acoustic transducers, microphones and electronic devices. Sophisticated signal processing allows
fast and accurate determination of the absolute polarity unimpaired by passive crossovers or signal waveform distortions produced by the device under test.The
test system consists of two units: the Signal Generator and the detector.To check acoustical or electrical phasing, the Generator is connected to the input of the
device under test whereas the detector picks up the output signal.
Subsequent signal processing enables the detector to decide whether the device under test reverses signal phase or not. The result of the test procedure is
displayed via two LEDS, the green one indicating the “in phase” and the red one indicating the “out of phase”condition.
Due to the versatile Input/Output structure of both the Generator and the detector any combination of acoustical and electrical input
and output may be realized.
