Is everyone using the 6625AF now?

Hoopty · 07-27-2004 -- 23:53:53

We've started using ours at Nellis, but only to chart the 1060 boxes for now. I think more will come online when its resistors finally come in.

BTW, I get WTF but BOHICA?

MIRCS · 07-28-2004 -- 06:17:03

Yeah we have been using our system for over 2 years now. We have the Resistors...got them a few weeks back. They are nice and do speed things up.

BOHICA......Bend Over Here It Comes Again

Mr.Steve · 07-28-2004 -- 06:29:35

Here's one for you all.

WTF! it's the SOSDD!

MIRCS · 07-28-2004 -- 16:25:37

Well Steve SOSDD.........Same Old Sh!t Different Day

Well on to the 6625AF. I have done alot of test and research on this item in the reversal rates, samples....etc. For charting the SR1060's a reversal rate of 10 is all that is needed....I know what the book says.....use a rate of 60, but I also know the results I've gotten along with Ken Eddy @ AFMETCAL. For samples......set the samples for 30. This will give you the desired results. Also you can chart the 1 and 10M decade boxes in either manual bridge operation or by using the Test Utility. You CANNOT use the Transfer Standard Utility for the High Ohm boxes in bridgeworks. I have some data on the reversal and sample rates. If you want it to prove to the evil QA that you can get these results by using other rates than what the manual says.....reply requesting it, shoot me an email or PM me and I will be more than happy to send the data to you.

Another thing is you need to make and attach guards from the block in the back of the unit to the UUT. This is paramount expecially with High Ohms. And remember that this is an active guard and will have voltage present on it.

And for an alternate email charles.dale AT moody.af.mil

Also Doug at Barksdale has done alot of research. Truly if you have questions on the system ask. Doug is very knowledgeble compared to me. he is a K8 guy as I'm a K6 guy. Though don't let me being a K6 guy scare ya......I know the 6625AF.

Has everyone gotten the Scanner excerciser off of METWEB yet???

MIRCS · 08-26-2004 -- 21:15:59

Boxes may not be charted with the Transfer Utility. Chart whatcha need in the Test Utility. The results I get are the same....though it states that the Transfer Utility is only good for the calibration.....ie 50ppm. Everyone take note.......thanks Barksdale for that one.

If anyone is ever sincerely interested in the full history behind the original specification (which was modified for acceptance) for this automated secondary resistance measurement system and any of the contracting details in regards to the 6625AF please feel free to contact me directly anytime. Do you realize the original contract award was made in July of 1999? How many systems are actually being utilized around the world today?

Okay, here comes the fun part. We have been trying to cal the SR1050 boxes with the 6625 with a new K-Pro. So far, all we get is that that "Servo has railed" using the method that the K-pro calls for. If you are not already familiar with it, let me explain.
The 1050 box goes on channel 32 and the reference channel of 22 or 23, depending on what box you are doing. After the hook up ,putting in the values ,channels, and references into the computer, and hitting start it will start to run. Then the readout on the 6625 goes all green and says "error 2" which in turn produces a dialog box on the computer which states the servo has railed. According to the book this can mean that Rx and Rs are not connected or that the ratio is too high. Just by using the K-pro, this should not happed. At least, that is to assume that this has been tried before the K-pro was put out. Has anyone out there tried to run it with this new procedure? Maybe you know something we don't?

Do you have the 4310 resistors?

Can you copy and paste the setup in the new procedure on this thread?

?

Well, my question is now moot. It turns out that everyone I have talked to for help has not had the same level of difficulty getting their system to work. Since my original post, our system has gone nuts. We're working the issue right now but we'll see how this all turns out. As for the procedure, I don't have anywhere I can copy from, unless I sit down with the k-pro and type it out. The procedure is: 33K8-4-467-1 dated 20051030.

cobychuck · 02-17-2006 -- 15:16:54

We found the problem! Our whole system has to go back to Guildline for repair! At least I now know it wasn't something I was doing wrong.

cobychuck · 02-24-2006 -- 11:57:50

Okay, a little more detail on the system failure. We ran the acceptance test from the com data and found that the current for the servo was half of what it was supposed to be. The 6622 had to go to the company for repair. That's why we kept getting the servo has railed error. Like I said before, at least it wasn't something I did!

Dang!

If you had that thing running you could have saved some time on the 5700As! We did one earlier this week and the resistance ran itself (except for three readings that didn't meet the TAR) and was done overnight (took about 8 hours). We had to run the three manually, but it was still a time savings over the old way.
