Review: Pretty handy but be careful for misleading result - This component is good for identifying components and 'estimating' the parameters for the components. However, please do not rely on this too much because sometimes, it's misleading. However, in short, it's a good device for getting some idea of your component, so I recommend this. Caution is like this. For LCR measurements, the values and parameters deviate sometimes significantly from the actual values from an LCR meter. For transistor measurements, sometimes it confuses the pin out of BJTs. For both of forward and reverse direction of a PNP transistor, it said that both were 'EBC', which was impossible. However, finding the base pin could be easily done by this. However, the zener function is really convenient. I can recommend this only because of that function.
Review: A great addition to my test bench. Combines several devices into one unit. - Review for FNIRSI LCR-P1 transistor tester. I used two methods to verify the accuracy of this tester. First, by comparing the readings against my multi-meter, and second, by testing known value parts and comparing the readings. First test was with an ancient Germanium transistor. The tester identified the lead pin out, the polarity as PNP, the Vbe (base to emitter voltage) and hFE (current gain). The hFE was close to what the multi-meter read. As another test tried rotating the transistor one half turn and reinserting into the socket and it still identified the leads correctly. Next, resistor function was checked. Again, the readings were very close to what my Multi-meter read. Then Capacitance function was checked. The tester will read value and ESR (Equivalent series resistance). The values matched the multi-meter with some exceptions. It read a 2000 Pf mica capacitor as 1nF (1000 pf) that is a 50% error. Yet the Multi-meter read the correct value. Next inductance was checked. It will show the value and DC resistance of the inductor. In this case I was only able to verify the DC resistance against the multi-meter. Also tested the zener diode function. The zener voltage shown was very close to the rated value of the part. Finally, used tester to read the codes of various infrared remote controls. It could not read all remotes, not sure why. This tester does have a few quirks. When you first press the test button to wake up the unit it will show "unknown/No component/Or damaged" just press the button again and the test will proceed normally. Also the value sometimes shows as only one significant digit (1 nf) not high accuracy. One more note and this is not mentioned in the manual when charging the battery, the LED indicator will change from red to green when the battery is fully charged. To sum up, this is a well designed tester which combines several devices into one unit. The instruction manual is clear and well written. The only drawback is there is no USB power module included, but if you are like me you already have several of these lying around.

### ⭐⭐⭐⭐⭐ Broken test lead
*by S***N on June 21, 2025*

Update to original Review ~~~~~~~~~~~~~~~~~~~~ I updated my review to 5 stars for the simple reason the support folk responded swiftly (within 36 hours) to my issue of a broken black lead and have shipped me a new set of leads to rectify the situation even though I clarified I only needed a replacement black lead. That's the kind of after sale service we all yearn for, a seller/manufacturer that cares about its customers. They say it may take 10 days for the leads to get here but they've given me a shipping tracking number and I'm perfectly ok with waiting. Thanks guys for caring. The meter continues to provide impressive results on analyzing and calculating the values of components I've tried. I realize some reviewers have noted issues but again, in cases where I can determine the part number of transistors etc, I've not had any issues testing the ones I have confirming them against the manufacturers specs. For the price, even though this unit seems very light weight and perhaps feels a little flimsy due to its tiny size, I'm impressed and will continue to add my recommendation, more so now I've received excellent after sales service to rectify a lead problem. At some stage I hope to find a small hard shell case I can keep it in but for now, I've retained the box it came in as it affords protection for the ZIF lever which protrudes out the side. Not a big issue. Original Review ~~~~~~~~~~~~~ To be upfront, I've emailed the support folks regarding this. If they respond and deal with the issue I'll gladly change the review but for now... Received the unit today. Here's the initial review. The unit is much smaller than I had expected. It works great!!!... but it is tiny. I tested transistors, mosfets. caps (various types), resistors, even tested the IR detector. IR detector worked just fine. It appears to give different codes for different buttons so I have no reason to disagree with the results. Capacitors tested were all correct results. Only thing I noticed is that the cap rating was within 2-3% of the caps rating. Some were spot on. None the less, I would say all caps tested were correctly identified. MOSFETs tested were all correct results. After reading reviews I decided not to just plug them in but checked online for the pinouts and use the leads. This is where I encountered a problem... The supplied black lead arrived broken! More on this later. I temporarily rigged up a lead from some other test leads I had. It correctly identified the MOSFETs I tested. Transistors. Same as MOSFETs, they all tested with correctly identified results per spec sheets I found online Resistors all tested correctly with the correct ratings. The screen display, while small, is very legible. I had no issues reading results and the color screen is actually very nice and clearly labels the pins on the connector. Very nice!!!! I did remove the ZIF and install the surface mount just to see it fitted okay. Not sure I'll use that part but wanted to see it fitted. The ZIF attached to the circuit board feels a little a little fragile but as I said, I will use this almost exclusively so I currently see no reason to remove/replace it with any frequency. So I'm totally happy with this setup for my situation. I did charge the unit using a standard 5v 2aH USB-C charger and cable. Charged fully within 45 minutes. No issues there either. So I have to say, very impressed. Everything tested thus far was correctly identified per the ratings either on the component or on the spec sheets. The black test lead arrived "broken". The test leads are not a great quality but none the less, one is broken. I've emailed support to see if they are going to replace the lead. If not I will return and request a replacement of the order from Amazon. If they replace the lead, I'll gladly change the rating to 5 stars because functionally I was very impressed with the unit. Now a minor quirk... Do NOT throw away the box... unfortunately, the unit is tiny and looks/feels fragile. Also with the ZIF connector, the lever sticks out the side so actually it's best kept in the box to keep it safe. I have no problem with that but the box tore very easy while trying to open so I ended up using some clear packing tape to strengthen it and hold it together. Still, this is a minor quirk and has nothing to do with the units functionality. So depending on whether the support folks are going to replace the broken test lead or I have to return it to get one that isn't broken, time will tell. I'll give them a week or so to respond and if nothing heard, back it goes for replacement. Yes, I would replace it because functionally, this does everything I had hoped it would do. If you do buy one, check the leads and meter functionality soon as you get it. If you're expecting it to give 100% ratings, you might be a little disappointed but as everything I tested came in 2-3% with some being spot on, it would be sensible to also note that the variance could be the components tested themselves. The electrolytic caps were new and some were used, the MOSFETs, other caps, resistors etc were all used (taken off dead circuit boards). I was testing things to see that they they came within an acceptable range of the rating and in my case, they did.
