To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
This tester keeps giving me different resister readings. You do a test and it gives me the reading. You test again with the same resister! A different reading this time. Every resister I do, it’s the same thing happening. So I don’t know which reading is the right one. I’m sending mine back and getting a different tester. It’s not that great sorry to say.
I really want to like this thing and I do for some things but man it's just awful on the UI side and calibrating it is a pain until you get it down.
I manually bought it for testing SMD caps and capacitors in general and for that it works very well in the capacitance test mode.
I'd have got another LCR for cheaper with a color LCD but I wanted the ability to use a Test lead for SMD stuff and possible in-circuit testing, know now this doesn't really do in-circuit but it's still very useful when it works.
I have my unit hooked into A 12V DC supply but if you on a 9V it runs it down fairly fast. You may get a month out of it on a battery if your testing a lot, I ran my 9V from 9.6 to 9.2 in a few days so it's not the best but it works.
My unit came with the whole screen protector right off the unit in the box which I thought was pretty poor but even then I have to give it a fair shot.
I may end up keeping it but honestly, 45 bucks is a bit too high when you can grab one for 30 on ALI or the various versions of LCR meters that suit your needs, it just may take longer, I was just impatient and wanted it quick.
You can upgrade the firmware somehow but I am not sure how, you may need some kind of flasher. Look into it on EEVblog if you are interested in doing that as the firmware is out of date by several versions.
Le istruzioni in inglese e cinese non spiegano sufficientemente bene come va fatta questa calibrazione. In ogni caso nella confezione non ci sono i puntali che, invece, mi aspettavo di trovare e che sembrerebbero servire per la calibratura. Aggiornerò la mia valutazione nelle prossime settimane appena avrò modo di usarlo.
