FNIRSI LCR-ST1 10KHz LCR Meter Tweezer, Mini Smart SMD Tester, ESR Meter, Multimeter, Capacitance Inductance Continuity Diode Tester, Auto Component Recognition Electronic Component Analyze

Admittedly, I haven't used it a whole bunch, since I have other tools in the arsenal, but I saw an electronic repair person use these and I was intrigued. It's great for doing quick on-board tests. It's accurate enough for quick measurements and finding opens and shorts and components way out of tolerance. I do like the auto flipping screen. It's a nice design touch. For the price it's a good value and the battery life is decent. It's a good, portable solution for testing caps and resistors and coils out in the field.

I’m very impressed how well this little unit works. Very accurate, easy to use, comes with a very nice case and holds a nice charge. I have been very impressed with FNIRSI lately and this meter is definitely one for the collection!!

It is well made and user friendly. The firmware is updateable so that's a plus. Works well but has limitations. If your are a hobbyist or DIY'er this is a good choice but for Pro use, no. Limitations are few choices of test voltage and test frequency and auto range is glichy. Doesn't always correctly identify the component under test. Download and installation of firmware update program needs better written English instruction. Once installed the actual device update is very easy.

For the money, a great unit. Used to measure audio cables. Compared to a high end Fluke meter, it’s measurements appear to quite accurate. Great for quick in circuit testing of various components.

Where have this been all my life! This small device is the greatest tool in my lab! It automatically detects the passive device and tells you the value. It’s so easy to use, features resistoance, capacitance, inductance readings with high accuracy. It’s very ergonomic and very thoughtfully designed. Better than your traditional multimeter and is a MUST HAVE!

Only for the support I received. I have other FNIRSI products and I love them! You cannot beat the price for the features. I bought these LCR Meter Tweezers open box and I suspect someone used it to test high power and it burned out the resistors inside and then returned them. When I reached out to tech support, support had more faith in me than I have for myself because they sent diagrams with the resistors to replace 😅 I'm all about fixing things but I bought these expecting them to work properly when I got them. I am not set up to replace chips that small. After some back and forward with support, they then just told me to go back through Amazon. Bummer, I needed them for today.

When I received my FNIRSI Bridge Tweezers, they were in Chinese language mode. It took me a while to figure out how to convert my device to English. There are three switches on the tweezers, an off/on switch, a mode switch, and on the side, there is a multi-switch that you may push side to side or straight down. . To change the language, turn on the device with a short press to the on/off switch. . Next hold the mode button down and move the multi-button on the side left or right and then back to the center. . The display will read something in Chinese. . Release the mode button next to the on/off switch. . Push the multi switch down to highlight the language. . Now you may rock the multi switch on the side to choose Chinese or English on the display. Choose EN. . Last, press and hold the mode button down, and your display will be in English. I hope this helps some users. I forgot to add this: My LCR tweezers work well. I tested it against a known bad electrolytic capacitor and a good capacitor. It is quite accurate and works as expected. I also tested it with some resistors. I use a B K Precision LCR meter to compare the results. It is well worth the money. Peter

Electrical engineering professor here. This is a FANTASTIC value. Other than having to set the language to English (easy), it is super easy to use. The screen is bright and clear, and I have tested it with precision resistance and capacitance standards and it is at least as good as the published specs. Really great. I have not used it much, but am debugging some designs now and my first impression is that it is amazing. I will update this review if I learn anything more, good or bad, but based on what I've seen today, I'd order one for each bench!!

These are awesome nice and small with inductors included in the test I find them to be more accurate than my uni t one and the case is a great addition to keep them dust free and safe.The unit has a 3 set frequency test condition which if it is slightly out you can set a different frequency and I have tried this and it does work quite well,There is a spare set of tips and they are right angled,I am happy to give these 5 stars as I think they are awesome.

Stopped working within a month of use. Showing random readings.

Great product, works as described.

Nice little tool,
