Тестер светодиодов и стабилитронов / Измерительный прибор

Sometimes you need to measure the parameters of LEDs or zener diodes whose markings aren't visible. Since such devices aren't available commercially, I've developed a tester for measuring LED and zener diode parameters. In this video, I offer step-by-step instructions so you can quickly build your own tester using inexpensive Chinese modules. I wish you success in your endeavors, and if you have any questions, please let me know. #otvintager Official developer website: http://otvintager.ru/ LED and Zener Diode Tester / Useful Device ===================================================================================== otvintager, #otvintager, tester, LED and Zener Diode Tester, Useful Device, how to make a tester, how to test LEDs, LED testing, Zener diode testing, how to test zener diodes, DIY tester, unique device, unique tester, LED tester, zener diode tester, otvintager, measuring device, zener diode parameter meter, parameter meter LEDs, ammeter/voltmeter, voltmeter, ammeter, LED parameters, LEDs, otvintager,#otvintager,tester, LED and Zener Diode Tester, Useful device, how to make a tester, how to test LEDs, LED test, zener diode test, how to test zener diodes, DIY tester, unique device, unique tester, LED tester, zener diode tester,otvintager, measuring device, zener diode parameter meter, LED parameter meter, ammeter/voltmeter, voltmeter, ammeter, LED parameters, LEDs, otvintager,otvintager,tester, LED and Zener Diode Tester, Useful device, how to make a tester, how to test LEDs, LED test, zener diode test, how to test zener diodes, DIY tester otvintager,otvintager,tester, LED Tester and zener diodes, a useful device, how to make a tester, how to test LEDs, LED testing, zener diode testing, how to test zener diodes, DIY tester ====================================================================================== Official developer website: http://otvintager.ru/ Lithium battery tester / Schematic and instructions #otvintager LED and zener diode tester / a useful device
