III. About your Presidium Diamond Mate
The Presidium Diamond Mate is a pocket-sized
instrument that instantly veries the authenticity of
diamonds based on their thermal properties.
It is based on an invention of Professor Julian
Goldsmid from the University of New South Wales in
Australia. Diamonds, with their exceptional heat
conductivity properties, are unlike any other simulants,
natural or synthetic, and are therefore not easily replicable.
As with all thermal testers in the market, the Presidium
Diamond Mate is not able to dierentiate between natural
diamonds and moissanite.
The Presidium Diamond Mate has been subjected
to thorough and extensive laboratory tests, and will
generally give a clear and reliable reading of the
gemstone being tested under proper use. However,
you are advised to conduct further supporting tests.
The Presidium Diamond Mate features the following:
• Retractable thermoelectric probe tip that ensures
constant pressure between probe tip and
gemstone
• Industry’s thinnest probe tip (0.6mm) for testing
gemstones as small as 0.02ct
• Metal alert buzzer to ensure that probe tip is in
contact with gemstone during testing
• No waiting time between tests
• Clear and easy-to-read LED display
• Low battery indicator
• Low battery consumption
Included in your package:
• Presidium Diamond Mate Tester
• User handbook
• Warranty card
• Protective carrying case
• 3 x AAA rechargeable batteries*
• AC adaptor/Charger (120/230 volts)*
* For PDMT-C only

1. GETTING STARTED with your Presidium Diamond
Mate
Powering up your Presidium Diamond Mate-A
This tester can be powered by either the use of an AC
adaptor (optional item sold separately) or through the use
of batteries. If AC adaptor is used, connect one end of
the AC adaptor to the tester (Fig. 1.1) and the other end
directly into an electrical outlet. Please ensure that only
the adaptor supplied by Presidium is used.
If batteries are used (3 x AAA batteries), take note of the
positive (+) and negative (-) directions of batteries when
inserting the batteries into the tester (Fig. 1.2). 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.
Fig. 1.1
Fig. 1.2
10
Powering up your Presidium Diamond Mate-C
Batteries will need to be charged for at least 6 hours
prior to the rst use. Simply insert the AC adaptor /
Charger (supplied with this model) into a
suitable electrical outlet. Your Diamond Mate can be
used while the batteries are being charged. A fully
charged battery should work continuously for 2 hours.
Batteries do not have to be removed when the AC
adaptor is in use.
Turning on your Presidium Diamond Mate
Remove the protective cover from the probe tip
(Fig 1.3).
Fig. 1.3
Fig. 1.4
Fig. 1.5
Press the [ON/OFF] button (Fig. 1.4) and wait for about
20 seconds to warm up the instrument.
While in this preparation mode, a Green light will blink
continuously. The light will stop blinking when it is
“READY” to be used (Fig. 1.5).
11
The tester will shut down automatically after 10 minutes
of inactivity.
Calibration
All testers have been calibrated during the manufacturing
process and no further adjustment or user intervention to
the tester is required.
Self-calibration should not be attempted. To minimize
any risks associated, users should contact Presidium
at service@presidium.com.sg or its service center for
assistance. In the event that users require the
manufacturer to re-calibrate the unit, the users will bear
the associated to/fro freight cost for the shipping of unit to
the service center.
Recommended testing conditions
The gemstone should be clean and dry before testing.
However, elaborate cleaning procedures are not normally
necessary (Fig 1.6).
The recommended testing temperature is 18°C-27°C or
65°F-80°F. Please allow the gemstone or jewelry piece
to adjust to room temperature prior to testing. Exposure
and/or operation of the tester outside room temperature
will aect the results and performance of the tester.
Battery information
Do not leave worn-out batteries in the battery
compartment as the batteries may corrode, leak, and
damage the tester. Batteries should be
removed when the tester is expected to be stored for an
extended period of time.
Fig. 1.6
12
To prevent inaccurate readings, replace with new
batteries as soon as the low battery
indicator lights up or starts to blink. A test should not be
performed when the battery power is low or weak.
Batteries do not have to be removed when the AC
adaptor is in use.
Cleaning your gemstone prior to testing
Prepare a clean tissue. Carefully retrieve the gemstone
with tweezers and place the gemstone face down on the
table (Fig. 1.7).
Gently rub the table of gemstone against the
tissue/jewellery cloth and place the gemstone on the
centre of the Test Pad (Fig. 1.8).
Fig. 1.7
Fig. 1.8
13
2. PERFORMING A TEST with your Presidium
Diamond Mate
Place the tip of the probe pen against the gemstone.
Apply minimal pressure to fully depress the tip into the
probe pen for correct reading. This is to provide steady
and constant contact between the probe tip and the
gemstone.
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 nger 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:
Place the gemstone on the metal stone rest and hold the
metal stone rest with one hand while holding the tester
with the other hand (Fig. 2.2).
Fig. 2.1
Fig. 2.2
Note : Metal stone rest is not provided by Presidium.
Tips for using your Presidium Diamond Mate
The probe tip must be placed at a right angle or
perpendicular to the facet of the gemstone for an
accurate reading.
14
Test should be conducted on the table of the gemstone.
In the event of any doubt, kindly test on the girdle of the
gemstones instead.
For proper operation of the tester, ngers must be placed
on the metal-plated serrated located on both sides of the
tester at all times.
To achieve optimum accuracy for tests involving very
small mounted gemstones (1.2 mm exposed diameter
and below), it is extremely important that no contact is
made on any mounted/ metal part of the jewelry piece.
To achieve optimum accuracy for tests involving very
small gemstones (10 points and below), it is important
to allow the gemstone to cool down before subsequent
tests.
It is advisable to take multiple readings regarding the test
results indicated.
Cleaning the probe tip
Please note that if the tester is being used for the rst
time, or if the tester has not been used for a week, it is
advisable to clean the probe tip using a piece of paper to
attain a consistent and accurate reading:
• Ensure the unit is switched o.
• Hold the probe pen with the pen tip forming a
right-angle (90-degree) with any paper or stone rest
(as provided). Gently move in a circular motion
without retracting the tip (Fig. 2.3).
• Repeat the same motion several times. The cleaning
process is completed and the tester is now ready
for use.

图 1.7
图 1.8
将宝石切平面抵住绵纸/首饰布轻轻擦拭，然后将宝石放
在检测台中央（图 1.8）。
27
2. 使用 Presidium Diamond Mate 执行检测
将探针笔的针头抵住宝石。 略微用力，使针头完全缩进
探针笔中，以获得正确读数。 这样做的目的是使探针头
和宝石之间保持稳定接触。
对于镶嵌首饰或镶嵌宝石：
一手拿住首饰或宝石，另一手拿住检测仪（图 2.1）。 为
了使检测仪正常工作，拇指和食指必须始终位于检测仪两
面的金属镀膜锯齿状部件处。 检测镶嵌首饰时应该小心
操作。 用户在执行检测前必须确保宝石镶嵌牢固，因为
宝石和镶托之间的空隙可能导致读数不准。
图 2.1
图 2.2
注：Presidium 不提供金属宝石底座。
如果检测的是裸石：
将宝石放在金属宝石托上，一手拿住金属宝石托，另一手
拿住检测仪（图 2.2）。
关于使用 Presidium Diamond Mate 的提示
为了获得准确读数，必须使探针头垂直于宝石的切割面。
28
应该在宝石的切平面上执行检测。 如有任何疑问，请在
宝石的腰棱上执行检测。
为了使检测仪正常工作，手指必须始终位于检测仪两面的
金属镀膜锯齿状部件处。
在检测非常小的镶嵌宝石（暴露直径不超过 1.2 mm）
时，为了达到最佳精度，切勿接触首饰的任何镶嵌/金属
部件。 否则检测结果很可能导致混淆，因为金属的导热
性很强，结果可能表明受测宝石是莫桑石。
在检测非常小的宝石（不超过 10 分）时，必须等宝石冷
却才能继续检测。
建议为显示的检测结果采集多个相关读数。
清洁探针头
请注意，如果检测仪是首次使用，或者检测仪已有一周未
使用，建议用一张纸擦拭探针头，从而获得一致而准确的
读数：
• 确保检测仪已关闭。
• 拿住探针笔，使针头与任何纸张或宝石托（检测仪
附带）成直角（90 度）。 慢慢做圆周运动，但
不使针头缩进（图 2.3）。
• 将同样的动作重复数次。 清洁过程即完成，此时即
可使用检测仪。
