Small update

We are still working on the program incl. talks.

Thankfully Nikolai Beev already agreed to join us live and talk about HPM7177.

Wekomm is also in and talks about resistor standards, which was already planned for MM2020.

Propably also Mr. Zirpel from the PTB could be with us and talk about calibration, but that has to be confirmed first.

John Pickering agreed to join us at least remotely and give a talk too.

A talk will be given by Eric Modica, Analog Devices, California USA, topic is secret

I'm waiting for two more confirmations for talks.

I was asked:

Is there a way for spectators to join the meeting during the online sessions?

The talks will be available via a Webex conference to everyone registered for the event. Depending on where you are located it will take quite some coffee to not fall asleep in the middle of the night.

Will anybody from northern germany (Bremen) join? Maybe one can share a car.

Hello Branadic, all - can anyone tell me if it is easy to take public transportation between airport of Stuttgart and University of Stuttgart - location of MM2021 event ?

I could arrive on Friday and return on Sunday ...

Thank you !
Best regards

Hi,

there is an underground from the airport to university as well as from the main station to the university. Unfortunately, the tracks are currently being replaced and some of the stations in between being renewed, so that underground doesn't drive. However, there is a shuttle service from the airport and the main station to the university replacing the underground. And guess what, three weeks of the renovation are over and the weekend 11.09.2021 is the last weekend of renovation, on monday 13.09.2021 underground is driving again as normal
Nevertheless, shuttle works perfect and drives every 10min on weekend and every 5 minutes during the week.

Hello Branadic & Folks - just confirmed that I will be present and hope to bring a METRON/FLUKE M7000 (ADR1000) and ADR1000 EVB ... - I will be on campus for 3 days - 2 nights.

Best regards
ScoobyDoo

Someone reported, that the above mentioned hotel has no rooms, so here are some alternatives:

Bus connection to institute:
•   Pullman Stuttgart Fontana
•   ibis Styles Stuttgart Vaihingen
•   Vienna House Easy Mo. Stuttgart

Within walking distance:
•   Römerhof Hotelbetriebs GmbH

Prior to the event all registered attendees will get a link to our Webex conference as well as links to the online discussion tables.
Webex can either be used as a local app or via your internet browser.

Morning,

just a quick overview of what visitors will bring to the live event:

- ein Keithley DMM 7510
- Ich möchte meinen Satz Kalibrierwiderstände (100 Ohm bis 10M) zur Kalibrierung und mein 34401 für Gleichspannung bis 100V / Gleichstom bis 100mA und ggf. Justage mitbringen.
- 1x KX-Ref, will attempt S7061 but this might not work out amazingly due to distances and transport (train) involved. And just maybe, if the stars align and me, JLCPCB and Mouser are fast enough- self designed LTZ board and/or self designed
- Bringe die F731B und die W 7 sowie die restlichen LTZ´s und eine LTFLU mit. Mit Prema 5017 sowie Agilent 34411A - ergibt wohl eine Messorgie
- K2000 mit Scanner, ESI Kelvin-Varney Poti, Selbstbau-Referenz mit MAX6279, läuft seit Mai 2019 mit einer Babyzelle (20000h), war schon beim MM 2019 dabei. Ich werde EMV-Bauteile für Tausch oder Verkauf mitbringen.
- 3 LTZ1000-References, Solartron 7081
- Möchte mein HP3458A mitbringen und evt. noch einen 4x Satz LTZ1000 Referenzen zum Nachmessen. Bin als mittelmässiger "Voltnut" an vielen Fragen zur Messtechnik interessiert und arbeite in der Branche als analoger Applikationsingenieur. Kenn im übrigen als ehemaliger LTC Mitarbeiter die  LTZ1000 Entwickler Carl Nelson und Bob Dobkin persönlich.
- Fluke 7000, LTZ #5 - battery powered 7,138V reference (Andreas design), several 10kOhm secondary standards (VHP202Z), a 1kOhm secondary standard (VH102), HP3458A, assortment of PTFE cables
- Geräte: 10 MHz Rb, Fluke 902, Knick U/I-Kalibratoren, Keithley 237, 34970A, vllt HP 8922 + 1kW SMU (19“ 3x 4U)
- Widerstandsbox, 1G Ohm Widerstand, LTZ1000 (branadic version), ADC (Kleinstein/Rerouter), Laptop
- Fluke / Wavetek 7001 DCV standard (powered) and Fluke 1 Ohm, HP 1 kOhm and Guildline 10 MOhm standard resistors. Possibly also Keithley 5155 1 GOhm resistor.
- Mitbringen würde ich einen Fluke 732B, der letztmalig vor zwei Jahren durch Vergleich mit einem beim MM2019 und der Maker Faire 2019 kalibriertem Fluke 732A von mir justiert wurde
- HP 3458A, Digibridge 1689, verschiedene Widerstände, Kondensatoren, Induktivitäten

We do have our 3458A and at least one 2182A in the lab connected to a RPi, but I will also have my F7000s with me.

For all of you arriving on friday, you can enter the institute and room from 4:00 pm on until 7:00 pm.

I'm so jealous! I'm on vacation on that day . Anyway, may be next year. Not sure how I could contribute to the event (apart for my small max6226 array). May be I'll make an oven-stabilized reference based on lm317 . If there is a competition "best cheap reference", I'd participate in that .

[branadic]

The time slot for registration is closing tonight.
We already hit the maximum limit for contributors for the live event. So if you haven't yet done, quickly register for the online event until tonight.

EDIT: In case you have registered for the live event, but can't join for whatever reason, please let us know, as there are more people that are waiting to join the live event, but we are limited to 20 persons maximum.

Small update to everyone arriving on Friday, actually tomorrow

I've booked a table for 8 pm at Sophie’s Brauhaus, Marienstraße 28, 70178 Stuttgart.

Thank you, branadic / André, for an excellent MM2021!

All the presentations were very good on interesting topics.

Regarding Keysights behaviour, I'm out of words. Please note that this in no way reflects on the splendid arrangement of MM2021.

Best regards,

eplpwr

Event was a blast, huge  for metrology professionals that did manage find time to show up and prepare excellent presentations. Special Thank you for organizers as well, you showing examples what can be done with a simple idea to get team together for good times.

Not just performance of actual product, but also events and stuff like this motivates today hobbyists and tomorrow business decision makers to choose these products and not the others.

My wish for Santa would be ADI sales team hearing and going forward with the desire from our small but friendly community to be allowed to buy ADR1000 parts (for full price, no need to do freebies).  Maybe 5 years from now we will see someone here start a company and design first 9.5-digit DVM 

[Kleinstein]

I don't think there is a real need for a 9 digit DMM, unless you deal with superconductiing parts. There are still not many references that low. The noise is usually not the problem at the high end DMM. The problem is more like the linearity and the thermal effects. Because of the thermal effects, the very high resolution measurements usually can't be fast. I see at least a chance to see a new 8 digit meter.

I found the persepective for the ADR1399 interesting as an easy update for an LM399 based design (if the voltage is about the same). Let's see if it will be actually available.

[rigrunner]

A very enjoyable event 

Big thank you to everyone involved 

Shame Keysight bottled it.

+1 for This ^^^
