• Keep the tester dry. Precipitation and all types of
liquids or moisture can contain minerals that will
corrode electronic circuits. If your tester gets wet,
remove the battery, and allow the tester to dry
completely before replacing it.
• Do not use, store or expose the gauge in dusty and
dirty areas. Its moving parts can get damaged.
• Do not use, store or expose the gauge in hot areas.
High temperatures 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.
• 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 the ne mechanics.
• Do not use harsh chemicals, cleaning solvents, or
strong detergents to clean the gauge.
• Do not paint the gauge. Paint can clog the moving
parts and prevent proper operation.
If your gauge is not working properly, kindly contact

IV. IMPORTANT NOTICE

1. GETTING STARTED with your Presidium Dial
Gauge
The Presidium Dial Gauge should be held in the palm of
either hand. Control the slider with the thumb (Fig. 1.1).
Ensure that the needle pointer is pointing to zero. If it is
not directed at zero, adjust it using the Fine Adjustment
knob.
Turn the knob of the instrument either clockwise or
anticlockwise to realign pointer to “0” position when
necessary. Zeroing adjustment is necessary when using
with jewelry attachment. (Fig 1.2)
Fig. 1.1
Fig. 1.2

10
When measuring loose stones, pull the Slider (Fig.2.1)
and place the stone on the Slider platform. Note that 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. 2.2) and place the stone
between the jewelry attachment and slider anvil.
2. PERFORMING A TEST with your Presidium Dial
Gauge
Fig. 2.1
Fig. 2.2

11
Slowly close the Slider (Fig. 2.3), the reading will be
shown directly on the Dial Face. With one measuring
done, the Dual Dial Face will show you three readings:
diameter in millimeter, weight in carat and ring size.
Functions of your Presidium Dial Gauge
Use the Wedge Shape Points when measuring:
- Stones mounted in rubbed over settings
- Interiors of empty settings
- Ring size
Use the Projecting Probe when measuring:
- Depth of mounted stones
- Width and length of large, loose stones, especially
fancy cuts
Use the Jewelry Attachment when measuring:
- Depth of stones in high settings
- Depths of stones in settings with small holes
Fig. 2.3

12
In the rst revolution, when the pointer travels from 0 to
0, it reads 0-10mm on the millimeter scale. At the same
time, it shows a direct carat conversion of 0.01-3.65ct on
the red carat conversion scale.
For example: Reading directly on the red scale, a round
brilliant cut diamond measuring 4mm diameter will have
an estimated weight of 0.23ct.
In the second revolution, it reads 10.1-20mm and a direct
carat conversion of 4.21-29.14 on the black color carat
conversion scale.
For example: Reading directly on the black scale, a round
brilliant cut diamond measuring 12mm diameter will have
an estimated weight of 6.29ct.
In the third revolution, the pointer will not go further after
23+mm, and it reads 20.1-23mm. No conversion was
provided for stones above 20mm.
The Range Indicator indicates each time the pointer
passes “0” 10mm or 20mm should be added to the
reading.
