Re: cheap aliexpress LC100a = $13 paperweight?
|
Doug, I bought one of these about 5 years ago. I replaced the L1 toroid immediately and got reasonable results. I can tell you that a big improvement came by using a rather convoluted calibration procedure that I read somewhere out on the Internet. With the "updated" procedure, my device gave quite good results. If you're curious, I can post that info, but I'd have to find it first. I replaced this meter with a DE-5000 meter, so I have little use for the AliExpress device. Good luck! 73 Mike M. KU4QO
I bought a no name LC100a on aliexpress figuring it was worth the risk as they offered free returns.? Unless I am really missing something, it looks like I will be taking them up on the free return.? I understand my testing method is awful.? 5% caps using one cheap device to compare to another cheap device should make most cringe but the Kaiweets meter is usually good.? Those are 330pf caps.? I have some 1% ones I should dig out but at this point I doubt it will matter.? I did run and save all the self calibration routines several times.? This is my fault for expecting anything better for $13 from a seller called Pure Pure Grocery Store but sometimes it is fun to roll the dice.? Fun fact, the price is already up $5 from 2 weeks ago.? Does anyone with one of these devices know of a trick I might be missing or as I suspect is this just more garbage made with floor sweepings?
