content: Welcome aboard !I for one am certainly a fan of SMD tweezers and their usefulness for general bench work and not just SMD !Can I suggest you add LCR Research's website link into your profile to get the blue globe link displayed so ppls have no issue examining your products or contacting you.If you need more forum exposure I suggest you send a set of tweezers to Dave via his mailbag and he might do an exclusive video about them.

content: Thank you for your advice. I will add a link to LCR Research and to mywww.toolsavvy.orgwebsites. Also, I will prepare both LCR-Pro1 PLUS and LCR-Elite2 and send them to Dave for review. Do you know the best way to contact him?

content: Welcome!A question : can I upgrade firmware on LCR-Pro1 PLUS ?Also, when I perform open/short calibration, it resets all settings. That shouldn't happen.Regards,

content: At this time only LCR Research can update the firmware. As a distributor, I can arrange this and re-calibrate the device. But, it will require some shipping expenses. What is your device shows when you go to the INFO screen?

content: Yes, your device can be updated with sw.r 3.01. I am not sure about losing config after self-calibration on sw.r 2.21. It must be firmware issue. I check sw.r 3.01 and it is keeping config. just fine.

content: I would like to see better probe tips for these things. Think spring loaded pogo style with bifurcated tip that 'bite' into the solder.Take a look at the Agilent infiniium probe tips. That is what i would like to see.Don;t know if the current one has this : rotating lcd display so left-handed people don;t have to read text upside down.

content: Quote from: toolsavvyorg on October 31, 2019, 04:56:05 pmThank you for checking that. That alone would be reason enough for me to update to newest firmware.For instance, if I start self-cal, it starts to beep after that although sound was disabled, i resets measurement interval to default etc etc...

content: I agree that test tips can still be improved. Using split Kelvin type tips will extend the 4-wire "Kelvin" connection to DUT. The "OPEN/SHORT" calibration taking care of tips impedance good enough up to 100kHz. But, if LCR-Reseach plans to design a 1MHz to 100MHz impedance analyzer - "Kelvin" probes is the way to go. (my opinion). Not sure thou how pogo pins will work with tweezers style handles.And, LCR-Pro and Elite both have "right/left hand" options.

content: Quote from: free_electron on October 31, 2019, 05:24:13 pmYeah, this. I have a cheap set of similar tweezers and the pointy "tweezer-like" tips are enormous pain, especially when trying to measure loose parts. They rarely make a good contact on a light touch and if you squeeze it a bit more it will make the component shoot out of the tweezers, never to be seen again.A set of "pogo pins" that you can actually use to press the part down with when trying to measure it would be a lot more practical, indeed.

content: The referenced website is really nothing I would point anyone to. First you are shown THREE products, with incomplete descriptions and a button labeled 'I want it' which will take you to Ebay. No, I do not want it - I want to read the invisible remainder of the description!Ok, trying 'Specifications'. Of the three products, only two show up. More crappy presentation and no specifications.When you try the 'Store', the 'Elite 2' is suddenly replaced by a 'Elite 1'. WTF? Is it the same or not?Not a single place to be found that directly compares their specs.While I can't say anything negative about those products, the way you are presenting them on that website does not give an impression of a serious vendor.

content: Quote from: janoc on November 01, 2019, 03:32:21 pmYes you loose the odd SMD and learn to use them more carefully however this is a good point, as the tips are stamped with slight curve so how hard would it be to have the die finely crosshatched to imprint the same pattern onto the inside of the tips ?The only issue I see is the longevity of the gold plating with a lesser contact area but it might be a good tradeoff for better connectivity.
