content: Hello All ,Raul is all set to start mass producing this tester .He did send me a video of the tool .Very Soon i will have the same for a small preview .Although the english translation from spanish is not that great you will still have a idea of the instrument .The Video Of ZETEXThe Link ->http://translate.google.co.in/translate?hl=en&sl=es&u=http://www.creatronica.com.ar/&prev=/search%3Fq%3Dwww.creatronica.com.ar%26hl%3Den%26client%3Dfirefox-a%26hs%3DkpO%26tbo%3Dd%26rls%3Dorg.mozilla:en-US:official&sa=X&ei=WV8NUbaFN8LUrQfNtIGoAw&ved=0CDYQ7gEwAA

content: lmfao that's even more ridiculous then the advertizement for that new hakko touch screen soldering iron

content: What a pointless product - for the number of times anyone needs to check a zener, a PSU, DMM and resistor will do just as well.

content: Quote from: mikeselectricstuff on February 02, 2013, 08:35:49 pmCorrect ,If i am getting ABCD of this video then it tests more then 30 volts diodes also right .Generally in the lab we have 0 ~ 30 volts supply only .Not Bad .As i said someone understanding spanish if can briefly tell what raul is saying might help ;-)

content: In India people still fixes TVs and electronics so this toom may be usefull from time to time, however, west world rarely go into component level repairs because new stuff is cheap so I dont see why I would need one.If I had one 15 years ago that could be handy.

content: I think the key work of this equipment is convenience - something that is very attractive if the price is right. Although the principle of the device is simple, this is very convenient to organize a blob of zener diodes or check if high voltage diodes, varistors, etc. are working.At the end it is mentioned that "I wish you find this useful for your repair work", which I think it is a good fit.The video may look and sound cheesy, but it sticks, which I am pretty sure that is the intent...A quick transcript of the video, skipping all the initial "poetic" part:(1:10) He mentions the need for the power supply and the initial self test.(3:00) He shows the device is powered by a microcontroller, and describes that its main advantage is that it shows the normalized standard zener values.(4:10) he says the device is able to test microwave oven diodes(4:52) mentions the behaviour of the device in a short circuit, at (5:00) he shows the behaviour in open circuit and at (5:10) the same behaviour with a reverse diode.(5:20) He explains the probes do not have power, unless the "measure" button is pressed(5:35) He explains how to enter the "calibration" mode, which shows the real voltage (and not the normalized values) by touching the negative probe to the small metal contact under the microcontroller. The display then shows the maximum output voltage in open circuit (186V).(6:36) He starts explaining other uses for the "calibration" mode, starting with varistors, and a damper diode.(8:05) he shows how to test MOSFETs (he explicitly says this withstands 500V). Initially he grounds both S and G and the device indicates an open circuit. Then he disconnects G and touches it, therefore making the device to indicate a short (0V).(9:28) he tests an infrared LED and notices that, despite the camera shows a small violet glow, nothing can be seen with the naked eye.(10:06) he mentions the high voltage is enough to trigger Neon lamps(10:28) he shows how to test an SCR. Initially the device shows an open circuit and, when he connects the G to the positive, the device shows a short.

content: Well,Thats not me i do not even have the tool .if i did it would be more like analysis then displaying a skull.though it looked really pro type .Hee hee thats rauls brain working there .Roul is a small time hobbyiest like everyone of us he is not weller .he will never make that much money as weller selling 1 unit in this video would .we should understand that
