Sun polarity tester 139B
Sunshine 139B polarity tester uses a pulse test, from environmental noise. Fast automatic identification speakers, headphones,, televisions, stereos, speakers and receiver coil positive and negative polarity, suitable for use on production lines. You can also use a foot switch external scanner and FO, impedance instrument, such as multi-use machine linked
Function IntroductionTechnical ParametersConfiguration Checklist
From environmental noise, and immediately determined that any type speakers, headphones of positive and negative polarity, suitable for use on production lines and research and development.
With three different instruments on-line test, only one person can operate, labor saving.
Easy to learn, easy to use, excellent reliability.
Basic specifications
Using pulse testing methods.
Determination polar ::
Pos: green light, buzzer called "beep" sound, for determining eligibility.
Neg: red light, determine the failure.
Sensor: ECM There are two alternative: one suitable for mobile phone and headset speaker, and the other for multimedia speakers.
Five kinds of touch buttons:
WF: suitable for subwoofer polarity test.
M & T: suitable for midrange and treble speakers and headphones polarity test.
Ext.1 ~ Ext.3: 152A can be connected to an impedance meter, 7117C F0 tester, 7116C scanner transition testing
