Abstract:
1. A testing apparatus for determining the content of precious metal within an object being tested, comprising: a meter including: a probe connected to said meter and including: a calibration system operably associated with said microprocessor to operate a calibration procedure that utilizes a calibration test reading from an application of said fiber tip of said probe to a known test specimen and compares said calibration test reading with a theoretical test reading stored in said look-up tables where said theoretical test reading corresponds to said known test specimen, said calibration procedure developing a calibrated response curve by applying an algorithm corresponding to the theoretical test reading in comparison to said calibration test reading so that all subsequent test readings will be adjusted to said calibrated response curve, said calibrated response curve comprising a response curve for said known test specimen from the look-up tables adjusted by the difference between said calibration test reading and said theoretical test reading, said calibrated response curve being used for all subsequent test readings for said probe until said calibration system is subsequently operated to create a new calibrated response curve.
