It can´t measure Germanium based diodes and (as I read here) also Shottky diodes ... so I think it has problem with low Uf voltage devices...
Diode polarity is not identified at all, and some diodes are even identified as resistors instead. Cannot recommend this for diode testing.
This was purchased for my Son as a gift, so the actual working data will have to wait until after he gets to use it. As a technician I am interested in how well it will work in my basement lab after he gives me a review of its operation and accuracy! It looks promising though!
The 100 MHZ scope and tweezer component tester can really fast and are of excellent quality.Just as anticipated. I highly recommend this company and their products.
I ordered these tweezers on a whim - I’ve been using a wired pair and external test gear and though that works, it’s a bit of a nuisance. Just from an advert I saw, and after I had ordered them, literally the day they arrived, read a review from Elektor magazine. These are really quite good and I quickly got comfortable with them. Don’t expect miracles, but for everyday use these are exceptionally good value for money. I’m at the point where I am thinking about these as gifts for some of my friends. Oh, yes, purely on the strength of this purchase and my satisfaction, I have already purchased the tablet oscilloscope and it’ll get here in a couple of weeks. I do quite a bit of field work and have an ancient portable battery powered scope from Tek that is a battery eater and has a miniature CRT, so it really was time to upgrade. Purely on a time-to-fix basis, the Tek needs new batteries, this is probably a really good solution.
I have some great lab-quality gear, but 95% of what I need is well served with these tools, so I will be recommending these to all my ham radio friends. Next month I will do a presentation for my local club about the tweezers and, if it’s arrived, the scope.
Congratulations to FNRSi on a good choice of gear for the average enthusiast. Here’s wishing you all success in your venture.
Good price and good accuracy but the diode check in V1.3 is bad. Cannot use to check BJTs or diodes. Need to upgrade to V1.5 which I understand fixes this. How to do that?
I bought three products and all them are very useful and good.
Incorrectly identifies the transistor terminals. In the photo, transistor H945, identified incorrectly. Schottky diode SR160 is identified as a 1.88 kOhm resistor (on photo). Firmware installed 1.0.6. If this is not corrected in future firmware, the device is absolutely unusable.
FNIRSI® 2C53T Upgrade Handheld 3in1 Oscilloscope Multimeter Signal Generator
FNIRSI is a wonderful enterprise: very good products, nice prices and a very kind and quick customer service!
Very nice item, as described. Thanks!
Very handy little scope, the signal gen is a bonus too.
FNIRSI® 2C23T Handheld Dual Channel 3-in-1 Oscilloscope + Digital Multimeter + DDS Function Generator
Well worth spending a little bit more to buy a 2 channel scope with smart functions for analysis over other standard one / two channel scope-multimeters.
DPOX180H nice for the price but be aware it radiates RF. Got this for audio work but found out that not so useful when working on FM tuner sections as it radiates a bit of interfernce. But for other than FM works ok.
best soldier tool ive ever used, buy it...
Very nice to work with it
Works good relieved timely!
...i will come back ;)
Ele não reconheceu nenhum triac. Ele não mostra o sentido do diodo, se virar o diodo ele continua costrando K pino 1. Ele não reconheceu diodo duplo, ele mostra como 2 resistores. Ele mostro beta 0 para alguns transistores. Eu comparei os resultados com dois testadores mais baratos o T7 e T7H e eles não apresentaram nenhum destes problemas. Eu estou usando a atualização 1.0.5 do LCR-P1. tem que ter uma atualização corrigindo tudo isto.
Dear Customer,
We recently released firmware version 1.0.6, which addresses some known issues. You can visit the Manuals & Firmwares page to search for and download the update.
If you need any further assistance, feel free to reach out.
Thank you!
Best regards,

FNIRSI® LCR-ST1 Mini Smart Tweezer LCR SMD ESR Tester
Very nice product, unlike cheap knock off which are being sold on Aliexpress.
The GM is decently sensitive and does the job.
You should consider implementing the superb firnware developed by Gissio and available on Github: it really boost the geiger counter into professional range
Funktioniert tadellos. Für den Hobbybereich und den gelegentlichen Einsatz ein solides Gerät
