Re: recommend ESR meter, Multimeter, hot air rework station
I know, it's been a while, but I just came by and noticed that the great and powerful Parker had responded to my comments; I thought I'd explain myself.
The BLUE ESR meter that I own was pre-built and I assume calibrated by Mr. Parker's trusted representatives. At least I assume he trusts them to send him checks once in a while. It puts out a wavering frequency of around 760 Hz that varies from 3.3 mV to -3.3 mV, in other words, it's basically an AC voltage. IMO, a meter that wavers this much can only make an 'estimate'...

Re: recommend ESR meter, Multimeter, hot air rework station
Excuse me, I was exhausted last night, and I should have said... '100 count' and '20,000 count'.
I have the Aktakom AMM-3035, the 'Blue' meter (purchased first) and three high quality DMM's, two of which read capacitance, but all three read frequency and resistance. I've been comparing readings with each to assess accuracy. At this point I have only discussed my tentative conclusions with a friend with a degree in EE, so I'm open to other interpretations. If I'm correct, there's a cloud of confusion and distortion...

Re: recommend ESR meter, Multimeter, hot air rework station
Why would you spend $100 for a 'Blue' ESR meter which only displays a 99-digit estimate of the ESR of electrolytic caps, when you could spend $160 for a professional quality, 20,000 digit, dual display LCR meter that measures capacitance from 20pF to 20mF (within 2.5%) using 5 different frequency signals (100, 120, 1k, 10k and 100kHz) along with the D (dissipation factor)/Q (quality factor)/phase angle [B]and[/B] ESR, in addition to L (20uH - 2000H) and R (20 Ohm - 2,000MOhm), the [B]Aktakom AMM-3035[/B] from [url]www.tmatlantic.com[/url],...

Hello. I was wondering if you would please tell me the values of C203 and c205 on your Sceptre power board, image "old.front.jpg"? I have the exact same power board in my Sceptre X9G-Naga III. Thanks
