I recently bought an AuRacle AGT2 Gold Tester.
I am finding that my testing results are not repeatable and that the tester is basically unreliable.
I have followed the instructions carefully and have watched a number of YouTube videos on using the tester.
I am calibrating regularly using a 14K plumb calibration button.
Typical example… I calibrated with the 14kt plumb calibration button, then tested known 10kt and known 14kt gold sheet.
Both tested accurately, but then I retested the 10kt gold sheet and repeatedly got results around 14kt. I recalibrated with the button and tested the 10kt sheet again and the tester read 14kt.
Does anyone have any experience with this tester??
