Re: [volt-nuts] do you like Labview in your labs?
Guys,
Didn't John just ask a couple of weeks ago that we keep things on
topic? When you make the subject line "Way OT" you clearly know that
it is off topic, so I don't understand why you are continuing a thread
on choirs, Wanamakers, panhandlers, and cellphone video quality. What
part of that relates to precise voltage measurement?

Seems to me that John was a part of this thread...

OK, I did join the thread -- but my posting was about programming
languages for data acquisition, which was pretty closely related to the
original, relatively on-topic, subject!
I recognize that the folks who inhabit both time-nuts and volt-nuts are
curious and clever, and that there will be off-topic diversions. I ask
folks to exercise self-control, and think that polite reminders are OK
when things do drift. But I also value my blood pressure so I try not
to get too heated up unless things degenerate into rudeness or complete
lack of respect for the other list members' bandwidth.

Mea culpa for bringing up the thread, but to clarify my rationale,
IMHO as I understand the needs:
Establishing a volt requires 3 things: hardware for creating and
sustaining a volt, its accurate measurement, and tracking variations
through time. To assist collecting data and measure its variation,
its best done in software.
Most discussion has initially centered on the building a stable a
zener based volt. For accurate measurement, there was discussion on
the HP/Agilent 3458a, and other voltmeters. But for tracking data
through time, not much. I had initiated a query on its need 6+
months ago, and this generated a set of replies with some nice graphs
of volt/time over short duration, weeks or days. And here we are at
the details now.
The question I raise was directed purely on the use of Labview or
write my own software, but it was related to the volt in this
way. On the software, the issue digressed but was strong related to
whether a platform be open-source or commercial, and analogies to
that, but this was pertinent to long term maintainability.
I currently have 5 months of initial observation data, and I'm moving
to fully automate it so it requires minimal input from me and it just
runs, as I need at least 1-2 years of data to confirm degree of
seasonal variations. This will best characterize ambient
temperature, pressure and humidity variations on a simple zener volt
reference; these phenomena have already been described in many
metrology papers.

Just as I cannot imagine time tracking in today's world without computer
assistance, I cannot imagine being a volt-nut without the same computer
assistance... I'm just not going to go back to hand drawn charts, and
chart recorders! A thread on Python, Labview, GPIB, and similar issues is
certainly relevant to me. Probably to others too.
I brought up the open source GPIB software and solutions because I would
much rather spend my limited coin on specialized hardware, than on high
priced software.

Hi all,
I'm having a forced downsize and my Solartron 7061 has to go. It's in good working order and condition and is complete with the correct input lead, calibration key and original manual. I've replaced the NVRAM nicad (with an auxillary supply connected to keep the calibration).
Don't really want to sell it but I thought I'd offer it here before it goes on ebay. I'm open to offers. I'll send it outside the UK but shipping will not be cheap, DHL to the USA would be £120. Please contact me off list if you are interested.
Regards,
Robert G8RPI.
