QTY:
Multi-functional transistor tester for automatic detection of NPN and PNP transistors, FET, diodes, dual diode, thyristor, SCR, automatic identification of the transistor pinout. Also can be used as square signal and PWM signal generator.

Features:
Digital LCD display for easy readings, can display measured data and graphics.
Rotary switch control, a key measurement for convenient use.
Main chip is the DIP, easy for electronic enthusiasts to DIY or update the main chip.
Use 9V battery(not included), can also use DC power(DC 6.8-12V).
Automatic shutdown, shutdown current is only about 20nA.
Automatically detects NPN and PNP transistors, FET, diodes, dual diode, thyristor, SCR, automatic identification of the transistor pinout.
Test NPN and PNP transistor common-emitter current amplification factor, the base-emitter threshold voltage, off the collector - emitter leakage current.
Support 2 resistors measurement, show its positive and negative, on-state voltage.
Resistance measurement maximum resolution 0.01Ω, can be measured up to 50MΩ.
Automatically test the pins of a component and show on the display.
Measure FET gate threshold voltage and gate capacitance.
For the following 2100Ω resistor while measuring its inductance measuring range from 0.01mH - 20H.

    Ce petit testeur de transistors et de bien d'autres chose est étonnant de simplicité, il n'est même pas nécessaire de connaitre le brochage d'un transistor bipolaire il le détecte automatiquement et indique à quoi correspond chaque broche ! Par contre il n'y a aucune documentation, mais heureusement que l'on peut trouver plusieurs liens sur Internet, dont le site du concepteur du produit avec toutes les évolutions du logiciel et les schémas du testeur. Dommage que les protections recommandées pour les condensateurs non déchargés n'aient pas été intégrées sur le module.

    J'ai acheté ce kit afin de tester mes résistances, condensateurs et transistors. Grâce aux indications fournies sur la carte, à la photo et aux vidéos postées sur youtube, le montage de ce kit a été effectué en deux heures. Commencez par souder les résistances, puis les autres petits composants, ensuite les plus gros. J'ai utilisé la plus petit panne du fer à souder, que j'ai réglé sur 330°. Attention, certaines résistances ne sont pas labellisées (il faut se fier au code des couleurs ou utiliser un testeur de résistance) et rien n'est indiqué concernant le sens dans lequel doit être inséré le processeur (long bloc noir plein de pointes argentées), il doit être inséré en ayant le détrompeur (petit point noir sur le processeur) en haut à droite lorsque l'on tient l'appareil en face (alimentation et potentiomètre à gauche). Attention, les condensateurs électrolytiques sont polarisés (2 en tout), si vous vous trompez, vous risquez de les détruire au premier allumage. Vérifiez la tension aux bornes des contacts 7 et 22 de l'embase du processeur avant de mettre le processeur en place, elle doit être très proche de +5v (le contact n°1 se trouve en haut à gauche). Il faut appuyer sur le potentiomètre pour allumer l'appareil. Il n'y a pas de boitier.

    Le seule problème que j'ai eux, c'est d'allumer ce machin. Grace au commentaires j'ai vu qu'il faut appuyer sur le potentiomètre.

    pour moi c'est parfait, surtout pour le prix ... fonctionne très bien, avec une tolérance plus qu’acceptable. super pratique pour le brochage de certains '3 pattes' attention la version kit ne contient aucune doc papier, mais la sérigraphie du circuit imprimé est suffisante pour le montage, a réserver aux personnes aillant l'habitude de ce genre de montage.

    Très rapidement reçu, très rapidement monté (une heure à souder). Ca marche du premier coup, pas besoin de manuel, on s'en sort facilement. Ca mesure pas mal de composants différents (de mes tests) : Transistors (jonction et FET) Diode (dont led) R C L Il y a même un endroit pour poser les CMS pour les tester (un de mes besoins justement). La précision de mesure est suffisante pour un usage amateur (qui est ciblé). Juste à lui trouver un boitier maintenant.
