content: Hi,I searched here in the forum and in the net about voltage references.My intention is to check my multimeter(s)...Mainly i found infos about the different voltage reference chips or circuit design discussions.But i would like to get a ready-to-use board. Beside the cheap chinese ones i could only find the voltagestandard.com site.The PentaRef looks good, even better the dmmcheck plus, but its out of stock right now.Are there some other boards in the market which are good ? Best would be if they are available within the EU.Thanks,Olaf

content: Quote from: sanman on January 18, 2017, 03:16:02 pmThat looks very good, but version 1 is not available anymore and version 2 not yet.And it would be more expensive than my multimeters...Quote from: TheAmmoniacal on January 18, 2017, 03:41:34 pmFew hours ago it was out of stock, but i got a response mail from Doug, he just updated the stock but it will take some time to get a DMMCheck plus because the meter used is out for calibration.But i think i will get one, because it has also current, frequency, resistance references...

content: Hi I have the dmmcheck with just voltage current and resistance and found it to be spot on, good value for money, worth the wait imo.

content: I ordered the DMMCheck even though it showed out of stock. I can wait...It may not actually be a problem, I got an email from the proprietor re: the 2d frequency option and he didn't mention any delay. But, if there is a delay, so be it.I didn't have one yesterday, last week or for the last 60 years, I guess I can wait a few days.

content: Thanks, but too late... just ordered the DMMCheck Plus todayQuote from: rstofer on January 19, 2017, 06:18:52 pmYes, it is in stock and i ordered the 2nd frequency too.But from today on their Reference Voltmeter is out for calibration, therefore we have to wait.Btw, which frequencies did you choose ?I will get 100 Hz and 8 KHz.Dont know why, just came to my mind
