I had the old white version that came out a few years ago that was fine but automatically turned off too soon which was annoying when testing multiple components. This one does turn off automatically as well but the delay must be much longer because I haven't witnessed it yet. The addition of the surface mount tester is nice and the internal battery lasts a long time. Very much worth the price

I have purchased several FNIRSI products.; and their 'Support TEAM' has been an awesome resource to work with.
It is the only checker that I could find which includes a Surface Mount Adaptor.

As a TRANSISTOR TESTER for identifying unmarked devices, the LCR-P1 fails only on one topic. It incorrectly identifies the CE pin outs on NPN transistors.

In the attached photo the displayed image identifies the Emitter connected to test slot 3; when the marked MPS6573 clearly shows that the Emitter is actually in test slot #1. But all other devices tested OK.

FNIRSI are attempting to fix this issue on the next downloadable update.

l'appareil a cessé de fonctionner a la 2e utilisation. Il donnait des releves erratiques sur le meme composant fois apres fois. j'ai demandé un retour et racheté le produit afin de savoir si c'est un probleme juste de l'unité recue ou habituel. la 2e commande a aussi ete difficile. l'appareil ne reconnait pas des composants habituels et donne des lectures differentes sur ceux ci malgré la mise a jour a 1.0.7. J'ai parlé avec le fabricant, il m'a posé des dizaines de questions, j'ai envoyé des photos etc. Rien ne semble l'inciter à me rembourser... C'est donc un parcours du combattant si vous avez pas de chance comme moi et tombez sur des appareils défectueux. Je suis insatisfait du produit et du service après vente.

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 �鶹��. 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.
