 PRODUCT OVERVIEWS  · MODEL : GJ3C · Vin : AC 85-265V · Vout : DC 0-330V · Iout : 30mA (TV Testing without Disassemble) 1mA (Testing for Small Components) · Pin : 20VA (MAX) · Temperature : -20℃ - ＋40℃  PRODUCT DEMOSTRATION  Plug the power supply (AC:85-265V) and wait for a moment: when the meter reads over 320V and remains unchanged, insert corresponding Red (+) and Black (-) pens to start testing.       Current Switch on 30mA:  a. LED TV Back-light testing without disassemble the screen. b. Testing of LED strip, LED panel, COB, integrated LED light source. (Do not look directly since the high brightness.)    How to test TV back-light with multiple sets of LED strips  The Voltage of LED strips should be the same in each group of TV Back-light. Otherwise, the LED strip is not normal.         Current Switch on 1mA  a. Testing of single LED bead, LED strip, COB, integrated LED light source. b. Determine the "+" and "-" of LED since NO BURN OUT even wrong polarity.  Test the voltage of Voltage regulator diodes, surge voltage of TVs diodes less than 320V, voltage of varistors, reverse breakdown voltage of diodes and the withstand voltage test of electrolytic capacitor.    Test the same LED panel with 1mA and 30mA       PRODUCT DETAILS       PACKAGE LIST  1x LED Tester 1x Test Probe(red * black) 1x Power Cord 1x User Manual       WARRANTY  1.
