ISO Posted August 15, 2009 Report Posted August 15, 2009 Hey guys if you go to post #68 I talk about the lower end version of the Vellman Scope. http://www.stevemeadedesigns.com/board/ind...st&p=608155 That should take you rite there. My 2 complaints about are, no matter how well you calibrate it the voltage was off by .7 volts to 1 whole volt when I used it with my Fluke 112 DMM. The second complaint is that I wish the AC ripples the scope shows you were alittle more sensitive or detailed. For what we do setting gains it still works great for it but if you have alot of gains to match I do recommend hooking up a highend DMM with the scope and once you have your numbers you need put the scope away and finish matching your gains on the rest of the amps with the more sensitive DMM. Twelve 2,000 watt amps. Do the first one with the scope and DMM hooked up at the same time. Get your voltage numbers, put the scope away and do the other 11 2,000 watt amps with the DMM. The Velleman is going to be at least a half volt off from the real numbers you need. Besides that I'm plenty satisfied with my Vellman HPS10se.

I already have a nice Blue-Point DMM, that is why I was looking for a cheap scope. Quote
Beanz Posted August 15, 2009 Report Posted August 15, 2009 Ahaha, what?It's an o-scope. Since when did we measure ohms with an o-scope... well i thought that youd need a certain one cause lie the higher end veilman one has it that you can measure the RMS nad peak all the up down to 2 ohms so that you could measure the ripples right but never mind then/ Quote That's why they don't deliver. Yer ass better go sit along the side of the road and wait. You can't expect them to travel up some dirt road in a hick / back woods town. Thats how horror movies start I explain things very simply and use analogies in terms of Pickles, and grape drink, pool noodles and jackhammers...if you can't put 2 and 2 together there man, There simply is not much more I can do.
