NOTE: This was posted by Jason on the 'old' forum:

Hello All,

My company has a set of standards (ranging from 1" - 24") that we sent out to be calibrated by a certified QS company. This set
is considered the "Master A" set which is the calibrated set. We also have another set consisting of the same standards, but we
consider this set to be the "Working B" set and this set is not calibrated. We have 4 pairs of tubular "C" outside diameter
micrometers ranging from 12" - 24". My question is: What is the appropriate method or procedure to verify our micrometers
are accurate using both sets?

We want to set up our system so that our operators will "work" with the "B" set & then every 6 months to a year, check the mics
agains the "calibrated A" set. Could this work for us & how would you record all of our actions.

Thanks...

Jason,

Dick responded to your original posting (which I reposted here) on the 'old' forum. I know you saw Dick's response, but for others it was/is as follows:

-------snippo------

Posted by Dick Lyons on Sunday, 28 June 1998, at 8:38 a.m., in response to Calibration & Verification, posted by Jason on Friday, 26 June 1998, at 6:04 p.m.

Calibrate your "Working B" set by comparing them to you calibrated "Master A" set. Now you can be confident that the operators have accurate standards to work with. This also allows the operators to double check their mics and other equipment against a known measurement anytime between calibration intervals.

Note from Marc: These 'comparisons' have to be documented in your Calibration System...

There are several software programs available that will provide you with the ability to record your calibration data as well as guide you in developing a good calibration system. Try downloading a GAGEtrac demo from from CyberMetrics Corp. at http://www.visit.com

Note from Marc: This url may be (pretty sure it is) incorrect. Hey Dick - What Say You??

to get an idea of what is out there. There are other packages but I just happened to have that one in front of me. Good Luck.

---------snippo--------

Now - Your last post on the 'old' forum:

I guess this message is for Dick Lyons who replied to a recent inquiry that I had... Dick, thanks for the reply. If there is anyone else out there with some knowledge of my needs, please feel free to reply to.

Dick, you suggested that I should look at CyberMetrics at www.visit.com, so I could download Gagetrac. I tried opening up this site, but I cannot get to it. Is this the correct address? It would be great if I could download something that is inexpensive to keep track of my company's calibration & verification procedures.

For those reading this message for the first time, I'll restate my inquiry. My company has 2 sets of standards that range from 1" - 24". One set is considered the "Master A" set which is the calibrated set. The other set is the "Working B" set which is not calibrated. We want our operators to use the "work" mainly with the "working B" set & periodically (6 months to a year) veryify their mics against the "Master A" set. I am looking for some formal inexpensive way to record our data and to meet QS requirements. Our data system doesn't necessarily have to be some high price computer software system either....but, of course, I'm sure that is more preferred.

If someone had a form that they use to keep track & control their calibration &/or verification procedures for their measuring instruments, it would be great if you could attach an example to my e-mail address:

my_con@email.msn.com

Marc Note: E-mail me a copy and I'll post it for everyone!

---------snippo-------

Now - This is in response to your Sunday posting on the 'old' forum.

You can make a form in a FilemakerPro, Access (if you support Bill G.) or another other database (FoxPro comes to mind) for ease, or just make a form in excel or other software. I've seen small companies actually comply with a paper system (but I don't recommend paper systems). The form needs the basics (like equipment type, serial number, etc.), but the main items are: reference point(s) being checked, 'before' reading(s) and 'after' readings.

You would be best off purchasing calibration software which addresses all the issues. The tradeoff between time maintaining a 'borderline' compliance system and just purchasing the software is - well, buy the software... You'll save in the short run, not to mention the long run... You won't regret it!

More and more registrars in QS are requiring proof of competancy in MSA so be careful. Someone in your company really (no kidding) has to understand MSA as a whole (the David Letterman Sky-Cam view) and be able and ready to explain how you 'comply'.

Try a search for CyberMetrics. I did this morning and was successful. There were several CyberMetrics listed but I selected CyberMetrics Corp. and went right to their page. If that doesn't work for you, give them a call at 1-800-777-7020 and have them send a demo disc.

Hope one of the above gets you the info your looking for.

Does this work? Hey Marc & Company....this new forum is kind cool & quite different from you previous forum. Is the other forum still accessible & if so, how much longer? When I post a message here, will I get my replies directed to my personal e-mail address, like the other forum did?

Well, for now, that's all I'll ask. I'll come back with my QS questions later.

The old forum remains up. I plan to leave it there as an info resource but *not* for any new posts.

I'm not sure about all of the software features yet. I know if you initiate a thread you have an e-mail option. I haven't seen where people responding have that same option. There are pros and cons to this software like all other software.

Jason, Microsoft Access is an excellent program to set up your data base. When you look at the sample software consider how many gages you need to conduct your verification on. Many of these software packages may have a lot more whistles and buzzers than you need. However, if you are not familiar with gage R&R protocol, you may want to have that included in the package. Many companies have talented personnel that write and design data bases, you may be able to complete your program by utilizing internal programers.

Use caution if you use microsoft's Access - it is not Y2K compliant. I forget whether they hacked a temporary pivot date fix or library lookup. But - testing has shown it is flakey (as is most microsoft software).
