2. PERFORMING A TEST with your SAM

Depress the tip of the probe pen against the gemstone.
Ensure the tip is fully depressed for consistent pressure
between the tip and gemstone for correct reading.
For mounted jewelry or gemstones:
Hold the jewelry or gemstone with one hand and the
tester with the other hand (Fig. 2.1). For proper
operation of the tester, the thumb and index finger must
always be placed on the metal-plated serrated part
located on both sides of the tester at all times. Care
should be taken when testing mounted jewelry. User
must ensure that the stones are securely mounted before
conducting a test as gap between stone and setting might
lead to inaccurate reading.

For testing loose gemstones:

metal stone rest with one hand while holding the tester
with the other hand (Fig. 2.2).
