Hi branadic,

I would also attend.
But I have only a 34401A, that was calibrated by the company of ap (Adrian). And 3 of your LTZ1000´s and a 100Ohm/1k/10k/100k self-build "resistor standard" that scream for calibration.

best regards

Since it is impossible for the PTB to send someone out for our Metrology Meeting I want to ask you guys for support of our event with a speech. As the event is casual and without tie every contribution is welcome. It's about sharing experience on voltage references, measurement equipment, be it bought or self-made and so on. So beside myself I presumably have one more member willing to talk. There is room for at least two more speeches.
I'm looking for your feedback to make it a valuable event. Thank you very much for your support.

Is this open if I just happen to have a HP3456A as my most precise instrument? I'd love to join you all there.

branadic · « **Reply #28 on:** April 24, 2019, 07:28:30 pm »

Sure it's open. I will spread a registration mail address within the next days.

Hello,

please count me in. Thank you for organizing it and the opportunity to take part of this event.

I do not know, if I'll have something ready for this event which is worth showing it, but I'll try.

And for the catering I'll bring two cakes, made by myself (Bratapfelkuchen and Käsekuchen).

Thanks again for the invitation,

Andreas

Most likely I will be there and combine visiting some friends over the weekend in the south.
Not 100% but pretty sure.

Harfner · « **Reply #31 on:** May 05, 2019, 08:38:44 pm »

Even as a complete beginner, I would like to come. I could bring a Prema 5000 (calibrated!) and would like calibrate a Philips 2534 which is far out of calibration.

e61_phil · « **Reply #32 on:** May 06, 2019, 08:19:07 am »

Will anybody bring a calibrator to the meeting? That could by helpful to calibrate some meters. 10V only isn't enough

DC1MC · « **Reply #33 on:** May 06, 2019, 10:29:46 am »

This will male me carry both the 1082 and 1071 Datrons. And yes, I'm coming

.

Cheers,
DC1MC

I also want to participate as an absolute beginner. I would like to calibrate my new LTZ1000.
My simple 6.5-digit Solartron 7150 shows a relatively strong noise, so accurate readings are difficult. To better assess the measurements, I have built an AVR application that constantly displays the mean, standard deviation, and temperature with linear regression through a ring buffer. In addition, the measured values can be stored on the SD card, e.g. for graphical evaluations. This helps a lot with normal laboratory measurements, e.g. in TC measurements of resistors. I will bring the device.

Don’t forget to post a summary for those of us on the other side of the planet

I can bring a Fluke 3330B but it is uncalibrated. Perhaps we can calibrate it, I have the manual for it.

branadic · « **Reply #37 on:** May 06, 2019, 01:28:56 pm »

I will bring my Datron 4000A, of course not calibrated yet. Received the new display PCBs today, so I need to assemble them within the next days.

Update: Attached is the official program. The event is free of charge, so hopefully this helps to motivate a few more people the join us. Please register by sending an email to metrology@hahn-schickard.de and let us know who is coming and what you are planing to bring with, so that we can estimate the required space for tables as well as lunch.
Hope to see you on 1st of june 2019 in Stuttgart/Germany.

Great, thanks! One comment: Once you get some feedback maybe it is possible to list what people bring, this way gaps can be identified and also those who wish to calibrate gear can see what is present.

Hi,

now I can say, that I'm coming too! And I'm looking forward getting to know everyone.

I will bring my z1000 ref's and my self-made resistance standard to calibrate.

Is somebody driving through the Ruhr area and can pick me up somewhere? PLZ 44651. Otherwise, I'll take the train.

Thanks to all,
H.-W.

Sadly I'm not able to come, but I still have (all diy) a dual 10V voltage reference and two resistor boxes that needs calibration.
Anyone willing to take them to the meeting and make some measurements?

dietert1 · « **Reply #42 on:** May 13, 2019, 08:14:55 am »

Regrettable, that nobody from PTB will join the event. Distribution of physical standards is their basic task and they get tax money exactly for that. But well, government doesn't work on saturdays.

Will anybody actually join with a calibrated 3458A or similar? I am near Karlsruhe and interested to get (for some fee) a 1 ppm or better measurement of our 10V standard (AD587 based). I think it is roughly at +8 or +9 ppm and would like to confirm that. Simple enough. Will this be possible in the afternoon?

Grüße, Dieter

Echo88 · « **Reply #43 on:** May 13, 2019, 09:27:26 am »

So it should be mandatory that a government agency should attend a hobby party for your convenience Dieter?

branadic · « **Reply #44 on:** May 13, 2019, 09:54:01 am »

It's not a hobby party, but an official event.
I don't complain about Henrik not joining the event. I do understand that he has a lot to do and family asks for priority on weekend. Henrik seems to do voltage references more for the hobby, as he is in another group at the PTB?
But I'm sad that none of his colleagues at PTB can/want to join the meeting, again it's an official event. I can't imagine that traveling costs are a problem.

However, I tried my best to get them for a speech, but had no success.

It's long ago, but i used to work at the PTB and i respect them.
No it's neither about hobby nor about convenience. It's about the safety of everybody's standards. I prefer to not send a standard by mail to somebody who i never met before. I think such meetings are a perfect place for checking a standard.

Regards, Dieter

ap · « **Reply #46 on:** May 13, 2019, 12:29:19 pm »

I plan to have a 732A with me newly calibrated with traceable MU better 1ppm. Same with 10k.

Here is what I have listed by now.

dietert1 · « **Reply #48 on:** May 13, 2019, 02:46:08 pm »

Great, i think i will join and also put our two HP 3456A into the car that appear to be very stable and may be useful as microvoltmeters for the direct comparison of standards.

Regards, Dieter

have you seen that posting from cat87 who is coming from your country?
Did you contact him already?
Otherwise, what dimensions does your stuff have?
I just want to make sure it will fit into the car of a fellow voltnut I'll go with.
Being located in Hannover you would have to get your gear to me.
There is an option to drop it off behind the border not too far away from Venlo if that fits.
