1. A device comprising:
a frame;
a striker;
a guide piece that includes a passthrough hole configured for the striker;
a transducer holder that is configured to position a piezoelectric transducer for test, wherein the transducer holder, which is positioned beneath the guide piece, exposes a first side of the piezoelectric transducer and a second side of the piezoelectric transducer; and
a first controller configured to:
analyze an output signal of the piezoelectric transducer caused by the striker traveling via the passthrough hole and hitting the first side of the piezoelectric transducer; and
determine, based on the analysis, whether a polarity of the piezoelectric transducer is correct or not.
