| 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. |
