Qualify/Calibrate???

[d.evans]

In the Probe utilities window, there are a few different "operations" from which to choose. What is the difference between "Calibrate Tips" and "Qualification Check"? I almost always choose "Calibrate Tips". But have wondered what the diff. really is. In the manual (3.7) the glossary says they are basically the same.

"Qualify
To qualify also means to calibrate, or determine the position (of a probe tip, for
example)."- p.1507

huh? Never used the other, only qualify tips.

The only time I have used Qualify is to check the calibration of the angles used, you select all the probe angles just like when you calibrate but when you select qualify it runs through what appears to be the calibration routine but when you look at the results what you see is the difference in the X,Y Z and diameter of all angles. Baically compares the angles to make sure they all calibrated well.

Thanks for the tip!

Qualification Check.......

A Qualification check will check the newly measured values against the last Calibration. This could be used if the Probe Head has been accidentally 'Knocked' instead of re calibrating all the tips, you could check 2 or 3. if they're OK then you wouldn't need to re-cal. Not much use in my opinion!! Never use it!!!

Haven't used "qualify" yet, but I will. I just got through with the "calibrate the unit" routine that error maps the PH9A for the tips you specify using a "T" shape tip configuation. The yaw, pitch, and roll are all calculated for the orientations you specify. I ran through this exercise for each A and B 7.5 degree increments, afterwards I was able to install a new probe configuration and calibrate only a few tips (I chose 9, min would be 4) and at the end of the process I had active selectable tips for the new configuration in all of the orientations error mapped in the "calibrate the unit" routine. So "qualify tips" can be used in the future to decide whether tips need to be calibrated but not necessarily all orientations will need to be checked. I'll have any orientation I should ever need, the ability to build and calibrate almost any probe configuration I should ever need, the ability to calibrate the new configuration very quickly, and verify any calibrated confuguration quickly as well.

Time will tell just how accurate this is, I'll let you folks know if I encounter problems.

I must have tried to do it wrong.
I select 3 different tip angles but keeps asking me to define 3 tps for calibrate the unit.
Also will this even work in 3.5 cad or do I need a later version or cadd ++ for this?

Tom,

I think this is a new feature in 3.7 mr3. To check from the probe utilities window select measure, the measure probe window pops up, in the type of operation box there should be a calibrate the unit selection.

Good luck,

yep.. I got that far when I hit ok thats when it keeps asking me for 3 tips. I figured it was a version thing..
Left behind again....lol

[tking]

Nope, if you got that far it's asking for a "t" shaped tip to run through the routine with. If you'd like I can get you a phone # to call me at to walk you through it. I'd try typing it here but I type with 2 fingers and I don't have that much time. Email address is available on the forum, send me one and I'll return with a phone #.

What is this "T" shaped tip that is being referred to in this thread? I've never seen one.
