■  DC Resistance and AC Impedance testable.

■  Built-in adjustable signal generator 20 Hz ∼ 8 kHz, external frequency input is available.

■  Upper / Lower limits  can be set.  Very fast judging  the  PASS / FAIL. Two LCD display impedance & freq., 152A can be used as a stand alone freq. counter.　

Used for testing the impedance and resistance of the receiver、loudspeaker、headphone ... etc., auto judging PASS / FAIL , can be used also as a frequency counter.

Electroacoustic  component  has  different impedance under different  frequency,  needs  to set a suitable frequency to test the rated  impedance  of such  component.  152A contains :  a 20Hz ~ 8kHz signal generator, two LCD display frequency & impedance.  Upper / Lower  limits can be set.  Very fast in auto judging the PASS/FAIL, suitable for 100% Q.C. in production line. 152A suits for the loudspeaker、headphone、receiver firms, also suitable for incoming  inspection of the audio、monitor &  multimedia  firms.
