Keeping the necro-thread alive … I just now found out about this and I certainly would buy one!

Just in case Doug should follow this …

kahuna0k · « **Reply #76 on:** December 14, 2018, 09:09:23 pm »

I would buy one too, and reading about how hard it is to build them, I'll be happy paying more than the $95 it is listed for.

Looks like it is possible to place orders at dmmcheckplus.com.

I received this email this morning:

================
Good Morning,

Thank you for your interest in the DMMCheck Plus and its availability. The DMMCheck Plus will be available for purchase this week, via a new web address that will go live today: dmmcheckplus.com . There are multiple options for this product based on your preferences, as well as a full page of additional information detailing the products functionality. The DMMCheck Plus can be ordered directly from the site, as long as the product is in stock. Boards ordered this week will ship next week (9/1-9/7). Please allow one day for optional programming and final calibration. Products will ship with calibration certificate.

Jordon Dudley
================

That is as much as I know about this.

Be careful. The domain name is odd and the name of the person is different.

A Whois on the domain finds the full address of the person, which is quite different than the person that originally sent me the unit.

Nevermind. I saw the note at the top of the http://www.voltagestandard.com redirecting to https://www.dmmcheckplus.com

I tried ordering one but when I got to the shipping options and made my selection there was no way to move on to the payment phase.

I was able to using paypal, but I had to click the final button twice for the payment to go through. I received a confirmation number and emailed receipt.

Got it to work as well. Tried last night with Paypal and it stalled at shipping options. Received an email this morning inviting me to try again and was successful. Have confirmation email with order number now.

I've just visited the website. There is a new option for two optional frequencies instead of the standard 100Hz.
I wonder if that would be another switch on the board to pick the frequency, is it going to be another set of stand offs to clip on?
And what do you think the most useful frequencies would be, the choice is in the range between 25Hz and 20kHz.

The second frequency has always been an option. You switch by switching to DC and back. The frequencies alternate. I think I picked 300 Hz as it can be divided down to all kinds of useful frequencies including 50 Hz and 60 Hz and 20kHz which can also be divided and lives at the opposite end of the scale so the total range is nearly as big as can be.

The DMMCheckPlus particular device is now being produced by a new guy with a new website. I've been on the orignal waiting list for the new ones when they came out this month and yesterday I finally got the email to tell me they were available again. I just ordered it yesterday and have an invoice number... hopefully it'll be here soon!

I recently bought a Datel DVC-350a from Calibrators Inc. that's rock solid (http://www.calibratorsinc.com/images/DVC-350Adatasheet.pdf) and I can't wait to compare this to it. Both my HP3456A and 34401A are within a couple 6th digit of voltages to the Datel. I love this stuff! I can't wait till my new DMMCheckPlus get's here. I ordered it with the case and the two frequency options.

R,

Bill

I also seemed to have trouble paying at first... but if you scroll down after it doesn't seem to work and again click the pay by paypal button... it worked!

R,

electricMN · « **Reply #86 on:** August 27, 2019, 11:11:38 pm »

There's no Paypal button to pay with. No button of any kind. I give up.

At the top of the checkout, you aren't seeing this? Do you have ad blocker or script blocker plugins running in your browser?

I'm not the person you're replying to, but I visited the site ealier from my laptop and I was just getting an error accessing the shop page. I get the same now on my desktop.

Quote

There was an error in fetching the product data. Please check back later and refresh this page

Using Chome instead of Firefox worked. I do run a script blocking add-on in Firefox, but it wasn't signalling anything was being blocked.

Very tempted to get this new model, but I don't have the budget for one right now. I have one I bought from Doug in 2012, which is reading 240uV high (well within the 5V +/-0.01% spec), and within 100uV of my notes from 3 years ago when I bought my 34465A (which may have also drifted). I also have a 3V reference from Doug also from 2012, which reads 280uV high, just inside the 0.01% spec.

Edit: I wouldn't be surprised if they're both pretty close to original spec, and the offset is in the 34465A considering its one year spec is 0.0034%. Good enough for my purposes, but I should get my 34465A cal'd at some point.

Edit 2: Actually, just compared the 34465A and my 34401A, and they agree to 1 LSD (34401A reads 10uV higher) - and I think the meters are probably more accurate long term so I'll believe them. All my other meters are 5.5 digit or less, and the two quite new R&S HMC8012 meters also agree. 121GW & BM869S both read high, but still damn close. I'll check my three old 3478A's later, but I know one has drifted compared to the others.

What makes you think it's a "new guy"?

notfaded1 · « **Reply #90 on:** August 28, 2019, 02:14:37 pm »

Maybe I should have said different not new.... I've been waiting for weeks on the list to get a new one and now he's making just the DMMCheckPlus and has a new website that just went live a couple days ago. I didn't mean any slight by the word "new." Different builder... same design.

Regards,

Bill

Do you mean by "different builder" that someone else is making them now?

notfaded1 · « **Reply #92 on:** August 28, 2019, 03:26:00 pm »

Here's the email I got from them to help you understand:

Hi Bill:
Doug is still going to do his 10V reference but has sold the DMMCheck Plus design along with his work on advancing the circuit and making it even more stable if that’s even possible…
We have the first set of boards inspected and they are being populated and getting ready for burn-in as I type. We hope to have the website up by next week and start shipping by the end of this month. The IC that is used becomes more stable after a substantial burn-in period. Same with some of the other components. The temperature stability is what we are after and so far so good. I will definitely reach out again when we are 100 confident in the reference which, if things keep progressing as they have been, will be this month.
Kind Regards,
Russ Keller

I hope that helps... I have 100% confidence in this new arrangement and we may even see a good thing improve... if that's possible.

Best Regards,

Bill

I picked 300Hz and 10kHz after reading your post! I'm excited to use to test my collection of nixie frequency counters... I have a bad habit and over 30 of them now o.O!

Regards,

Bill

maginnovision · « **Reply #94 on:** August 28, 2019, 06:39:42 pm »

I'm not surprised Doug sold it off. He did say it was a lot of work to build, burn-in and support these.

Noy · « **Reply #95 on:** August 28, 2019, 06:54:28 pm »

Hm i have an old one. Got it in January this year. Whats new now?

Ordinaryman1971 · « **Reply #96 on:** August 28, 2019, 06:58:42 pm »

I wonder who's supporting calibration of the old version... mine is due in October.

All I see is this:

Maplewood_Ken · « **Reply #98 on:** September 12, 2019, 05:40:56 pm »

Received today, USA midwest. Shipped from Wake Forest, NC. Thoroughly padded and shipping box tightly closed. Probably delayed a couple of days by Dorian.

Instructions and calibration certificate (measured values) included. Probably won't get to try it out until the weekend, at least.

Hi,

Any plans for group buy in EU?
