ET4401 Benchtop Digital LCR Meter / Product review for East Tester LCR Bridge ET4401 ET4402 ET4410
Ғылым және технология
In my opinion, a very good, low cost, worthy every coin paid for a LCR Bridge solution. In fact, this is my 2nd unit, so I can recommend this product.

Thanks for the video. You were really lucky. I got my ET4401 a couple of weeks ago and no, it was not a 100kHz one 😢 so East Tester probably don’t want to surprise us anymore. I did find that the firmware version was differing greatly. I have version 6.00.2136.018. That’s a lot of revisions ahead of yours (?) 😯 the East Tester quality/warranty card says it was built September 2022. It is a beautiful addition to my ET3240 and I’m very happy with it and hope it will last long! Saludos from The Netherlands.
You have some great test equipment Bob ! .. certainly make your job a lot easier
Hi, very good movie, could you make some video about et4410 during an reparation? So se can see how to use It during some device repairing.
can I ask you a question please, would a hi frequency lcr meter (5 Mhz) be of any use in a pcb repair lab? already have a hp 4263A up to 100KHz.

Hi! Most of the time, a LCR Bridge is used as component meter. ...and we try to test the component on the same frequency than the Datasheet's specification. Also some Electronics Laboratories uses Vector Network Analyzers to try to test or measure a PCB "internal capacitance, inductance, or conductivity". But VNA works only on high frequencies. And here is the tip: Some Labs uses LCR Bridges to try to do that test, but in low frequencies. (Most of the times, the SMPS frequency and until its 5th harmonic). Let's remember LCR bridges have many frequencies available, because we want to test the component on its datasheet specs and also on the frequency the component is working in our PCBA. That's the reason why we got so many "low frequencies options about". Thanks for asking!

@@bob.kalpon1398 thank you for replying.
Purchased one, unstable screen, (L) inductance didn't work, returned it. BAD BRAND
Not everyone in the world spells frequency with a q lol.
only u explained bias
