A. Types of Error Messages when TESTING
During testing, you may encounter the following messages
appearing on screen to inform you of a possible error.
i. ‘Connection lost’
This (Fig 6.1.1) indicates a loss of contact between the
probe pen and the gold sample.
Possible causes:
• Probe pen sliding/moving on the gold sample/jewelry
• Uneven/rough surface of gold sample/jewelry such
that contact is not fully made between the probe pen
and the gold
Suggested solutions:
• Hold the probe pen against the gold sample and
ensure this position is maintained until the on-screen
progress bar is completed during testing
• Prevent sliding/remove during testing with a steady
hold
• Find the flattest surface on the gold sample and hold
the probe pen steadily at that area, making sure there
is full contact when testing
