Reading Test Results On Your - PRESIDIUM Multi-Tester III (PMuT III) User Handbook Manual

3. READING TEST RESULTS on your Presidium Multi Tester III
The test results are indicated as follows:
1. Red LED lights up:
• Gemstone with high thermal conductivity such as
sapphire or topaz is detected.
• Gemstone with low thermal conductivity such as
glass or cubic zirconia will not give any reading on
the tester.
2. Yellow LED lights up:
• Moissanite is detected.
3. Green LED lights up:
• Diamond is detected with a continuous audible beep.
• Metal is detected with an intermittent beep at "Metal"
segment.
Note: For stones with lower thermal inertia, the
Presidium Gem Tester / Color Stone Estimator (PGT/
CSE) or the Presidium Duo Tester (PDT) can be used to
further differentiate the type of simulants as they detect
a wider simulant range.
