Multi-functional transistor tester: 1)Automatic detection of NPN and PNP transistors, fet, diodes, dual diode, thyristor, scr, automatic identification of the transistor pin out. 2)Used as square signal and pwm signal generator. 3)Measure fet Gate threshold voltage and Gate capacitance. 4)Used as signal generator and frequency meter: frequency range from 1hz-2mhz and can generate 1%-99% pwm(pulse width modulation) signals. Notice before measuring capacitance, the Capacitor must be discharged, otherwise very likely to damage the meter. Specifications type: assembled tester / DIY kit Display resolution & Size:160*128 LCD; 3.7 * 3cm / 1.45 * 1.18in Power supply: 1 * 9V battery; DC 6.8-12V; Current: Approx. 30mA Resistance measurement & resolution: Max. 50Mω; 0.01Ω Capacitance measurement & resolution: 25pf~100mf; 1pF DC Voltage measurement: up to 50V PCB Size: 7.8 * 6.2cm / 3.1 * 2.44in Package weight: 69-73g / 2.45-2.57 oz Package Content: Transistor tester DIY kit as shown in the picures.

it arrived quickly and in good condition, but with no documentation
This is quite intriguing: it arrived quickly and in good condition, but with no documentation. Having read other articles I checked the six reference resistors (which didn't seem as high tolerance as their banding suggested) and substituted 0.1% ones from another source. The circuit worked first time. I still have to work out its operation - turning it off seems a bit hit and miss at the moment. The resistance measurements appear to be accurate. Recognition and measurement of other components seem good, but I have nothing to corroborate them yet. All in all it will be very useful. Operational documentation (for the particular software programmed into the supplied processor) would be very helpful.

Kit de prueba y testeo de transistores
Kit de calidad regulera (pero muy bien para el precio que tiene) para trastear y probar la polaridad de los transistores.Viene totalmente desmontado, así que solo para entretenerte montándolo tienes un rato. Si trabajas mucho con este tipo de componentes puede valer la pena, y seguramente tengas algo mejor, si no, no está mal como apoyo.

nicht ganz zufrieden
Keine 5 Sterne! weil:Lieferung war zwar schnell schnellAlle Bauteile in einer Tüte: großer Mangel!Keine Bauteileliste / Lieferliste: ein sehr großer Mangel, da keine Eingangskontrolle möglich!!!Bauteile schlecht beschriftet, schlecht zu lesenLieferung war zwar vollständig, konnte aber erst umständlich verifiziert werdenkein Hinweis auf SMD BauteileGerät funktioniert nach dem Zusammenbau
