B. Human Errors when TESTING
i. Testing on calibration disc and result does not show “14K”
Sometimes, to ensure your device is working accurately,
you may wish to test on the provided Calibration Disc
which is of 14K gold. If you do not get “14K” as your result
when testing on the calibration disc, these could be the
possible cause and suggested solutions.
Possible causes:
• Calibration was done incorrectly, calibrating on wrong
material
• Calibration disc is not clean
• Wrong color of gold selected in <<Settings>>
• Probe tip has been worn out
• Sliding/moving when doing calibration
Suggested solutions:
• Re-calibrate again using provided Calibration Disc
• Ensure calibration disc is clean by cleaning it with
eraser provided
• Go to <<Settings>> and ensure ‘Yellow Gold’ or ‘White
Gold’ corresponding to the color of the test sample,
has been selected and set
• Remove the worn probe tip and replacing it with a
new one (It is recommended to change the probe
tip if calibration errors are persistent and/or incorrect
reading of calibration disc occurs more than 3 times)
• Prevent sliding/moving until the on-screen progress
bar is completed during calibration
ii. Non-conductive samples tested with results as ‘Not Gold’
Non-conductive samples should never test as ‘Not Gold’ as
‘Not Gold’ refers to conductive metals that do not contain gold.
Possible causes:
• Size of non-conductive sample/gold sample is less
than 2.5mm thickness
• Testing liquid when dispensed has touched the
conductive plate instead of the sample
Suggested solutions:
• Ensure that when testing a small/thin gold sample
of less than 2.5mm thickness, the sample is placed
across both the conductive and non-conductive plates
on the Testing Platform and the probe pen is held to
the part that is on the non-conductive plate.
