Re: ESR Meter
Thanks a lot Kripton and Haran. I think it is clear how to calibrate.
Haran, I understand your remark about compairing good and bad capacitors. That is of course the most important function. But the reading is very accurate, so I do want to make it as precise as possible (I know it is a tick of me...).
One question about the 4066. I also saw a design of Elektor (Combi-C-Meter in sept. 2005) and they state that it is better to use a high speed version (HC4066). This to avoid unwanted reactance (or half it). Any thoughts about that?
Disadvantage of that meter for me is that you have to switch between C and ESR measurements.
Rob,Well I haven’t tried yet with 74HC4066 chip and I don’t think so you’ll see a Significant Changes by using 74HC4066 maybe not. I’m happy with CD4066. The device is fast quick display showing ESR & Capacitance.
Actually both chips are same price here in Canada. Two for a dollar if I get a chance I’ll try and let you know the feedback.
As far as I know Go ESR is the best complete open source available and smart people could tweak the ASM file Also comparing to Peak Atlas ESR I’m happy with the outcome and quick results. My buddy owns a Peak Atlas he’s surprised with this unit
