• Keep the gauge dry. Precipitation and all types of
liquids or moisture can contain minerals that will
corrode electronic circuits. If your gauge does get
wet, remove the battery, and allow the gauge to dry
completely before replacing it.
• Do not use, store or expose the gauge in dusty and
dirty areas. Its moving parts and electronic
components can be damaged.
• Do not use, store or expose the gauge in hot areas.
High temperatures can damage or shorten the life of
the gauge, damage batteries, and warp or melt
certain plastics.
• Do not use, store or expose the gauge in cold areas.
When the gauge returns to its normal temperature,
moisture can form inside the gauge and damage
electronic circuit boards.
• Do not attempt to open the gauge other than as
instructed in this handbook.
• Do not drop, knock, or shake the gauge. Rough
handling might break internal circuit boards and ne
mechanics.
• Do not use harsh chemicals, cleaning solvents, or
strong detergents to clean the gauge.

Inserting the battery into your Presidium Electronic
Gem Gauge
1. Pull the battery slider sideway outward using either
ngernails or a screwdriver.
2. Place a CR 2032 3V battery with the (+) sign facing
upward in the battery compartment and close by
pushing the battery slider sideway inward (Fig. 1.1).
3. The use of alkaline batteries is preferred, as it should
generally give approximately two and a half hours of
continuous operation, while the use of ordinary
batteries will give a shorter working life.

Battery information
Do not leave worn out batteries in the battery
compartment as the batteries may corrode, leak or
damage the gauge. Batteries should be
removed when the instrument is expected
to be stored for an extended period of time.
1. GETTING STARTED with your Presidium
Electronic Gem Gauge

• The Presidium Electronic Gem Gauge should be held
in the palm of either hand. Control the Slider with the
thumb (Fig 2.1).
• When measuring loose stones, pull the Slider (Fig. 2.2)
and place the stone on the Slider platform. The base of
the stone should be parallel to the platform to prevent
it from moving.

When measuring mounted stones, insert the jewelry
attachment to the gauge (Fig. 2.4) and place the stone
between the jewelry attachment and Slider anvil.
• Slowly close the Slider (Fig. 2.5), the reading will be
shown directly on the display window. Press MM/Ct
(Fig. 2.3) to convert between dimension in millimeter
or weight in carat.
