Sorry, Our complimentary calibrations that were intended primarily for our customers and our products that were on our website were being severely abused by other companies/people. We started doing tech support for other companies products and we can't afford to do that.........We have a ton of time and money in R&D in all our products that we feel our customers may benefit from. There are many people/companies in this industry that feel the same way, unfortunately this industry this has become very bad about ripping off, and copying others ideas for free. I know I speak for many of us that are hard working, honest, and frustrated that this situation continues to seem get worse. Rant over....................
