Re: Schaffner NSG 2070
HI Bob, keep begging mate It was never made available. When the product was transferred to Germany for Manufacture, all knowedge was lost. I dont know where you get your info, but I get mine from the designer. now long since retired. Any drivers that were published I wonder as to their usefullness, and what program they were intended to be used with. Non of Schaffners software has ever controlled the NSG in the public domain. Like I said, the RS232 bus was for set up and calibration... BTW, I looked at the site and didnt find drivers... only a reference that they may exist As for controlling the various bits... you would be better served getting individual components, or using the system as intended. Or, better yet, gettingt he newer system that does have more user control and is fully compliant to current ( and future ) specs.

The User's Manual that I have, chapter 8 Remote Control, states: The command set is normally not necessary but is, however, available upon request for special applications. http://www.schaffner.uk.com/support/technotes/tn-006.htm This page has drivers available for the internal power meter and signal generator. Obviously, Schaffner felt there was a need to control the device externally. Why would anyone want to bypass the internal firmware?? We have a lot of EMC equipment with internal firmware that can run a test, like EFT and surge generators, but we still use software to control the device since it gives us better control and documentation.

Re: Need manufacturer information about conductive tape
Hi I think you have tape from Adhesive Research in Ireland. I found this at ApplianeMagazine.Com Adhesive Research Ireland Ltd., a European developer of pressure-sensitive adhesive tapes and other coated products, announced several recent personnel changes. * Aideen O'Neill joined the company as senior chemist for the its Medical and Pharmaceutical business units. * Barry Murphy was named an RD technician, joining scientist John O'Mahony and senior technician Karen McCarthy, who will provide RD support for the Splicing business unit in addition to their existing RD duties for the Electronics and Industrial business units. * RD technician Hilda Russell moved from the Splicing business unit to the Medical and Pharmaceutical business units. * Karen Burns was appointed to a newly created position in Customer Care Technical Service for the Industrial, Electronics, and Splicing business units. * Bernadette O'Connor was named customer service representative. Also, Tee Wee Ang joined Adhesive Research Pte Ltd. as new regional sales manager for its Japan, Taiwan, and China territories. The company¹s ARclad® 90038 and Flexshield® 8269 are said to be highly conductive pressure-sensitive tapes designed for electromagnetic interference (EMI) shielding. The ARclad 90038 is a 2.4-mm acrylic-based tape, featuring a 1-oz, tin-plated, copper-foil backing. Its shielding effectiveness ranges from 95 to 80 dB in the 1 to 18 GHz frequency range. The tape¹s tin-plated backing can be soldered, and is reportedly resistant to corrosion and oxidation. The Flexshield 8269 is a 4-mm tape featuring an Electron® nickel copper-plated woven polyester fabric carrier. The tape¹s shielding effectiveness is 90 to 80 dB in the 1 to 18 GHz frequency range, and is said to offer flexibility and conformability, resistance to cracking from repeated flexing, and weight-reduction advantages. Adhesives Research, Inc. http://www.appliancemagazine.com/sd/sd_company.php?company=61 Since I have used their tapes for years, I strongly recommend that you consider 3M conductive tape You can find this web page through Google for 3M conductive tapes solutions.3m.com/.../home/productsandse vices/products/TapesAdhesives/ElectricallyConductiveTape/ - 65k - Best regards Bob Schlentz appro...@minn.net __ This email has been scanned by the MessageLabs Email Security System.

That says it all, really. It's far cheaper to buy the standard than to struggle with an old version, wonder about the problem and wait for answers from your colleagues, and it costs them money, too, to prepare the answers. What is the specification for the fastest response time for a voltage change? That is, at what point should a voltage change be recorded (.displayed, measured)? The instrument incorporates complex filters with very low bandwidth. There isn't a 'go/nogo' level above which a change is recorded. For example, If there were an instantaneous voltage change of 5V, a drop and subsequent recovery lasting only 3-5mSec, are the specifications such that the flickermeter will measure that? The response to such a change is very small indeed. Should it measure it as 2 step functions? I gather from EN61000-3-3, that measurements of each half-cycle (at the zero crossing) are analyzed. However, looking at Appendix A of 60868, table A1 the meter MUST have the capacity to measure voltage changes as great as 1620 per minute. It follows that the sample time would have to be in the range of 600uSec rather than 10mSec. 1620 per MINUTE, 27 per second. For Dmax does the meter only analyze adjacent half cycles with respect to voltage changes? I'm not sure what that means. Does it average very fast voltage changes that occur during a those measurement periods? Yes, averages them into insignificance with two bandpass filters in cascade; the first has a pass band of 0.05 Hz to 35 Hz for 50 Hz instruments or 42 Hz for 60 Hz instruments, the second is a narrow filter centred on 8.8 Hz. The bandwidth of this filter is not specified; what is specified is the transfer function of the two filters in cascade. These filters model the effects of voltage fluctuations on the light output of 60 W gas-filled coiled-filament lamps, different, of course, for 230 V and 120 V lamps. -- OOO - Own Opinions Only.

RE: LabVIEW Example Codes for a Position Controller
Please see comments in a previous thread on instrument control software, as I should not repeat my dogma (or my catma) Do not understand your question, because a VISA driver is directly usable by LV (if you want me to consider LV to be 'useable'). FWIW, I wrote a (simplistic) driver while at a previous employer for an older version of this box; a boring chore. If you are concerned about demonstrating control of your code (IEC 17025), then your best bet would be to write a DLL in C, then import to LV, then use the Call Library Function Node.vi via Tools/Import/Shared Library. Finally, if the driver is compiled with a .NET tool, just use the LV .NET palette to get at all of the available nodes. There is certain to be an app note available on the NI developer zone website.

From: John Woodgate Sent: Thursday, August 23, 2007 2:11 PM Tarver, Peter writes: In a practical sense, for solder be effective, you probably need a solder pot, a flux and a short, neatly twisted tip at the end of the thermocouple wires. Sacred cow say, 'Do not twist'. No, I don't know why, either. Only the contact between the wires at the extreme 'inboard' end of the twist is effective as the thermojunction, though. The rest only adds mechanical strength. The twist could be as little as a half turn and is only intended to bring the two conductors into contact with one another, prior to soldering. The heating effects of the solder pot could allow the wires to be drawn away from one another, due to either different coefficients of expansion or stresses in the wires due to local hardening (from processing or being bent in handling ...) I don't twist the ends when I weld thermocouples, but I've seen instructions on welding that say to do so. The point nearest the 'free' ends of the thermocouple wire is where the temperature will be measured and will act as the junction. If a twist is a cm long, there's probably 9 mm of irrelevant (to temperature measurement) wire at the end. Possible oxidation of the conductors and relatively high ohmic contact increases the inaccuracy of a measurement. As Bob Johnson pointed out, open-circuits are a big problem, but on some occasions, especially when I've leant thermocouples out, the insulation is abraded during removal. If care is not taken, it's very easy to not notice bare wires near one another. An anecdote: I once created a set of sixty+ 20' long, 30AWG, Type T thermocouples to measure temperatures in a hydrogen fuel cell to be placed in a large environmental chamber (20' left about 3'on the outside of the chamber). Made from scratch, it took about five hours to make this batch. The customer insisted on removing the thermocouples, rather than allowing one of our staff to do so, to whom I gave instructions to be careful with them. Their method: yanking on the wire where it exited the enclosure. I was not pleased with what was returned to me. Some sections I cut out were four and five feet long. Regards, Peter L.

Flickermeter response time
All, My question is not regarding the flickermeter per-se but the measurement of the voltage fluctuations: Dmax specifically. I don't have a copy of IEC1000-4-15, nor can I seem to find the information from the older IEC 60868. What is the specification for the fastest response time for a voltage change? That is, at what point should a voltage change be recorded (….displayed, measured)? For example, If there were an instantaneous voltage change of 5V, a drop and subsequent recovery lasting only 3-5mSec, are the specifications such that the flickermeter will measure that? Should it measure it as 2 step functions? I gather from EN61000-3-3, that measurements of each half-cycle (at the zero crossing) are analyzed.However, looking at Appendix A of 60868, table A1 the meter MUST have the capacity to measure voltage changes as great as 1620 per minute. It follows that the sample time would have to be in the range of 600uSec rather than 10mSec. For Dmax does the meter only analyze adjacent half cycles with respect to voltage changes? Does it average very fast voltage changes that occur during a those measurement periods? Thanks for any insight.
