Nice product but beware it will tell you the wrong polarity on diodes, transistors, and leds. No matter which way the diode is oriented in the tester the polarity will always show the same.

I used it for testing transistors so far so good

Couldn't say if it works well. This is a little more updated that another, less expensive tester, without a lcd screen or box.First step is to D/L an update. It locked into a state i Couldn't get out of.It appears to need a phone app to do this. Why? What possible need is this? Exposes phone data.I had to let it run down overnight to get control back. Returned without any use.

Very cool little tester fir the price. Dies have a little anomaly with bipolar transistors. Sometimes it identifies them as an f.e.t. When they are not. But seems to work pretty well.

Besides identifying the characteristics of transistors, diodes, zener diodes, etc., this device will give ballpark readings of R, L, and C. Not as accurate as my LCR meter but often it's good enough.

I received it less than 24 hours after ordering. That’s amazing. After charging the battery, I gave it a shot. After every attempt to measure, I got the “component missing or unknown” message. So it’d take the part out, clean the leads, and put back in. Then it would usually work. I’ve since discovered that it *always* gives that error message the first time you push the Test button. Ignore it, push it again, and it will work the second time.I previously had one of those earlier versions that cost about half as much and is without an enclosure and uses a 9V battery, but it conked out. Anyway, I think it was more accurate and had a faster response time than this one. This one is pretty accurate with resistance (maybe 1%), but maybe not as good as the older model with capacitance and inductance. Capacitors measure about 7% off or more. Not terrible but maybe could be better. Inductor measurements are similar with 10% or more error. It’s hard to judge the accuracy of BJT, JFET, MOSFET, but those checks appear OK. One good thing - I was surprised at the published high end of the range for C and L, and I verified it will measure ten times or more what’s specified.

Muy buen artículo, funciona muy bien, lo malo es que al actualizar el software es un poco complicado y confuso, de todo lo demás muy bien.

Functions well. Instructions aren't great, but test results seem consistent and sensible. Reasonable value for money

I've been using this tester for quite sometime and here's my review1. Functionality - resistors, capacitors, diodes, triodes, etc tests accurately2. Accuracy is within accepted limits3. It's easy to use and intuitive4. Overall, value for money product

I tested a variety of individual components in my parts bin. This works as advertised. A very low value inductor was identified as a resistor, but then correctly measured. A larger inductor and a speaker were correctly identified as inductors, reporting impedance and inductors. Transistors were correctly identified. Connect devices to any of the numbered pins, which pins has what polarity or function will be identified.When pressing "Test" to power up, you will need to press it again to test the device. I missed this fact and thought the thing was broken. 3 test leads and two fixtures are provided to assist in connecting. I don't know how this will perform for devices in a circuit. That also depends on the circuit. It has a shorting relay for capacitors but I suggest shorting them before testing.One problem with more expensive testers is that any testing device can be misused and damaged. This one features "Less tears", a very low replacement cost. For a beginner with limited knowledge, that's an important feature.
