"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"

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!rosalind rosenthal

Convient little tool and helps you diagnose issues quickly! Unsure as to accuracy but works well enough that I was able to fix a broken bassinet within minutes. Very happy. Seems to work great. (Ignore the messy table. Haven't had time to clean up)uri b

Given the low price of it, it's a good solution for measuring small SMT resistors, capacitors and inductors for their resistance, capacitance or inductance. But it is not suitable for measuring typical ESR values of small capacitors or inductors, as these are typically too small for it to give reliable and accurate results.princely

When I first saw this, I thought this was a gimmick, but a friend convinced me to try it.I was pleasantly surprised by how well it works. The component readings are accurate. The screen size is large and bright enough to be functional.The user interface could use some improvement, and the tips could come together better, but I will overlook those for how well it works overall!What Customers Talk About
