Main Features
● Automatically detects NPN and PNP transistors, N-channel and P-channel MOSFET, diodes ( including dual diodes ), transistors, resistors and capacitors
● Automatically test the component pins and display them on the liquid crystal
● Can detect the amplification factor and base of the transistor, MOSFET protection diode, etc. Determine the forward bias voltage of the emitter transistor
● MOSFET measuring the gate threshold voltage and gate capacitance
● Display uses 12864 LCD ( 128 x 64 characters )
● Higher test speed, expiration component test: in 2 seconds ( except for larger capacitors, large capacitance measurement takes longer, the 1min measurement time is normal )
● One-button operation, boot test, one button to get.
● Power consumption off mode
● Can avoid unnecessary waste, save battery energy and improve battery life.

    Buon prodotto ma manca la perfezione nel contenitore
    A parte che non legge alcuni componenti come Thyristor e SCR, alcune resistenze e alcuni condensatori, ma sembra un buon prodotto, forse non molto completo. Un piccolo manuale soprattutto per interpretare le letture non avrebbe fatto male. Speravo dicesse anche il componente ma per esempio gli zener fa vedere solo un doppio diodo senza indicare la tensione di lavoro. Il contenitore e bello da vedere ma in realtà non è molto preciso. La parte superiore in plastica dalla parte del flat per il display non sono riuscito a montarla in quanto il flat e anche il display, bloccano l'inserimento dell'inserto. Ho dovuto limare il foro del pulsante in quanto avvitando le viti spingeva il pulsante blu contro la plastica trasparente. Ho dovuto limare un angolo della plastica in corrispondenza della leva in quanto andava a toccare. Di mia iniziativa ho messo tre viti che bloccano il porta batteria per evitare di muovere troppo il cavo rosso e nero quando cambio la batteria. Penso di avere trovato quello mal assemblato. Ma adesso funziona bene. Se avete un piccolo manuale per favore inviatemelo. Lo consiglio in quanto per la spesa irrisoria è utile.

    Did not work
    After an interminably long wait for the item to be shipped and delivered (45+ days) I assembled the items into the supplied clear plastic box only to find that nothing appeared on the screen when a battery was connected. I disassembled the components and tried various charged batteries to find that the screen lights up but displayed nothing.
    Thought about returning the item but considering the wait it took for the item to arrive I am UK and item was shipped from the Netherlands supposedly (obviously on the back of a snail) I decided to bin the lot and looked and purchased one from Amazon.
    I assume they do work according to the reviews but mine just didn't :(

    Having said that, it is the first item I have purchased from Gearbest that hasn't worked :(

    (RO) Pachetul a venit destul de repede, circa 3 saptamani. A ajuns nevatamat. I-am construit carcasa (destul de usor si fara desen) si l-am pus in functiune. Spre surprinderea mea functioneaza perfect. Am testat mai multe componente...Functioneaza super. Recomand celor care au ca hobby electronica si au un mini-laborator acasa.
    (EN) The package came pretty fast, about 3 weeks. He got unhealthy. I built his case (pretty easy and without drawing) and put it into operation. My surprise works perfectly. I tested many components ... It works super. I recommend those who have an electronic hobby and have a mini-home lab.

    nice piece of equipment full of potential for further improvements
    This is an amazing piece of equipment for people with functioning hands and brain. It comes fully disassembled and it took 30 minutes, at least, to assemble it, as no instruction manuals were provided. But once assembled, it can surprise in functionality as gives quite accurate diagnostics on resistors, capacitors, diodes and transistors.

    I have one wish to the developers of the product. Please try to improve the product design so that replacement of the battery would not require to disassemble the whole box. Maybe some easy to lock-in removable battery cover?

    Handy device for electronics hobbyists
    This device arrived as a partly assembled kit. The PCB was ready assembled but the perspex case came in its component pieces. Half of the fun was figuring out how to correctly put it together without instructions but it didn't take long and is a really nice piece of kit. I wish I had one years ago when I worked with electronic components all of the time. Just poke a resistor, capacitor or diode in the socket for a quick display of the component value. Recommended for the electronics hobbyist.

Hello, is it included with case

By Henk Jan-29/2019 09:07:35

Hello Henk, Thank you for your inquiry.  Yes,it is.

Hello, can it measure inductance? There is inductance measuring among product images, but there is no word in product description about it. Thanks in advance.

By Robert Dec-29/2018 18:40:45

Hello Robert, Thank you for your inquiry.  It can't measure inductance.

Is this a kit or assembled?

By mark Nov-29/2018 16:22:23

Hello mark, It is assembled.
