The only link I found is this: https://www.electronicspoint.com/forums/threads/smart-lcr-tweezers-lcr-pro1-russian-rlc-tweezers-hb-14.291164/page-4. But unfortunately that thread has some very contrasting information in it, and does not look very balanced. Will read up on them some more. Added: They are also known as NV-14 it seems. And have been mentioned here before: https://www.eevblog.com/forum/testgear/tweezers-for-low-impedance-capacitors/ Manufacturer website: http://rlc-esr.ru/index.php/en-us/multimetr-pintset-nv15 But the manual only seems to exist in russian. |

bateau020, read all 5 pages of this topic. Don't pay too much attention to the messages from caps is a troll known by various names. He is trying to measure a very clean ESR to 6 decimal places on a dial gauge marked with a thick felt-tip pen. :D |

I try to explain why do these tweezers cannot support milliohm resistance. Because they said they cannot support in the datasheet. :palm: ST5S has an offset spec, For the resistance ≤ 25mΩ LCR Pro1 has a similar spec, looks like the offset is ≤ 20mΩ |

But I got used to it, know how to read what I want and I don't care. It doesn't make it less good or useful, although I agree with you that it is silly. --- End quote --- I also agree with you and did not want to offend you as the owner of this device. But I am critical of when a manufacturer (seller) for marketing purposes does stupid things that customers don't need. I know of a few really serious tweezers that are worth the cost, like the HB-14 or the newer HB-15. But I don't know if these tweezers are sold in your countries, since the author and manufacturer of these devices is from Russia. --- End quote --- :-+ No worry, no offence taken, I just like to be direct and also meant no offence. I agree that many manufacturers choose marketing over truth, and hate it as much as you.. I know about HB14 and HB15 and would have bought them, but it's not simple importing from Russia ... They seem like good instruments. If only we could organise sales here in EU, I believe they would sell well. Best regards |

Maybe there is an opportunity for an EEV branded tweezer. |
