Important Notice - PRESIDIUM Synthetic Ruby Identifier User Handbook Manual

It is known that due to impurities or transition metal ions that are
usually found in natural rubies, these stones are able to absorb
deep UV light. Thus the UV transmittance ability of such stones is
low. For synthetic flame fusion rubies, it was found that they usually
did not contain such trace elements or impurities. Hence, the UV
transmittance ability of synthetic flame fusion rubies is high, allowing
the UV wavelength to pass through the stone.
This knowledge was shared with the Gem and Jewelry Institute of
Thailand (GIT) which recognised and endorsed this methodology of
utilizing the UV-VIS-NIR spectroscopy to measure the transmittance
for identifying synthetic and natural rubies.
Believing this was a radical new methodology to identify certain
gemstones, GIT also loaned Presidium a substantial sample size
of both natural and synthetic ruby stones for testing and identifying.
Presidium was able test these stones using the Synthetic Ruby
Identifier and have the tests confirmed using GIT's advanced
laboratory equipment. Working closely with researchers at GIT who
readily shared their gemmological knowledge, testing trials for the
Synthetic Ruby Identifier were also conducted by GIT for Presidium.
V. Important notice
• Keep the device dry. Precipitation and all types of liquids or moisture
can contain minerals that will corrode electronic circuits. If your
device gets wet, remove the battery and allow the device to dry
completely before replacing it.
• Do not use, store or expose the device in dusty, dirty areas. Its
moving parts and electronic component may get damaged.
• Do not use, store or expose the device in hot areas. High
temperatures can damage or shorten the life of the device, damage
batteries, and warp or melt certain plastics.
• Do not use, store or expose the device in cold areas. When the
device returns to its normal temperature, moisture can form inside
the device and damage electronic circuit boards.
• Do not attempt to open the device other than as instructed in this
handbook.
• Do not drop, knock, or shake the device. Rough handling may break
internal circuit boards and fine mechanics.
• Do not use harsh chemicals, cleaning solvents, or strong detergents
to clean the device.
• Do not paint the device. Paint can clog the moving parts and prevent
proper operation.
