The aesthetics are of excellent quality, the management interface is intuitive, and the measurement has also proven to be reliable.

Es ist ein schönes und für Hobby Elektroniker erschwingliches Gerät mit einer guten Genauigkeit. Es wäre großartig, „Deutsch“ unter den Spracheinstellungen zu haben.
P
LC1020E Bridge is very accurate measuring device due to its Kelvin clips. Such clips enables voltage testing direct on the measured device terminals, this way eliminate parasitic effects of current cables impedance.
I am very satisfied.

Highly versatile and configurable equipment. Good measurement accuracy. It's a reliable piece of equipment.

I was searching for decent handheld/portable LCR tester. Mostly for air inductors measurement. Had some air coils on stock measured with high-end equipment and I must admit this is on par. Very happy with the purchase. It's easy, portable and works. Hope it will last for few years at least.
M
Very versatile unit , exactly as described, fast delivery and well packed, I will use it a lot in my work shop
n
Resistor and inductance measure ok, but large size capacitors are not accurate.

All good! I received mine about 3 weeks ago, and it's getting plenty of use. The only thing I'd like to see added would be a soft case so it gets a bit of protection on the workbench. Shorter test leads ( about 15cm ) with clips would also be a benefit compared with the ones supplied ( about 1 M long with no clips ). Accuracy and repeatability seem good and the functions are pretty intuitive. One component test I use it for is grading N.O.S. capacitors for use in guitar amps. My old Heathkit IT-28 could tell me if something wasn't right with an old capacitor even if didn't indicate measurable leakage compared to a modern cap of the same value, but the LC1020E shows any leakage problem clearly ( using the 1st C setting and 2nd Q setting ). For that it's a real time saver. The photos show a much higher Q for a new poly cap versus a N.O.S. paper cap. The LC1020E is also great for component matching. So yes, 3 weeks in, I'd recommend the fNIRSI LC1020E.

I really enjoy Fnirsi products because they are practical, reliable, and genuinely useful in my everyday life. I appreciate having tools that make my daily tasks easier and help me solve problems quickly and efficiently.
What I like most about Fnirsi is that the products are designed not just to look good, but to be useful in real-world situations. I use them regularly, and they have become valuable tools in my day-to-day activities.
For me, a good product is one that you can trust, use often, and immediately see the benefit of — and that is exactly what I find in Fnirsi products.
I’m happy to recommend Fnirsi to anyone looking for practical and useful electronic test equipment for everyday use.
