1. GETTING STARTED with your Presidium Multi Tester III

Powering up your Presidium Multi Tester III

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.

Fig. 1.1

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. 1.2

Turning on your Presidium Multi Tester III

Remove the protective cover from the probe tip (Fig.1.3).

Fig. 1.3

Press the [ON/OFF] button located at the back of the
tester (Fig. 1.4). and wait for about 20 seconds to warm
up the instrument.

Fig. 1.4
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).

Fig. 1.5
The tester will shut down automatically after 10 minutes

of inactivity.

11

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
[e-mail] 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).

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 the room
temperature would affect 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 or damage the tester.
Batteries should be removed when the tester is expected
to be stored for an extended period of time.

To prevent inaccurate readings, replace with new battery

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).

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. 1.8

13

2. PERFORMING A TEST with your Presidium Multi Tester III

Place the tip of the probe pen against the gemstone and

press the test button. Apply sufcient pressure on the tip

for correct reading.

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.

Fig. 2.1

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. 2.2

Tips for using your Presidium Multi-Tester III

The probe tip must be placed at a right angle or
perpendicular to the facet of the gemstone for an
accurate reading.

14

Tests 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 rubber pads 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.
The test results will likely result in confusion, as metal
is highly conductive and results may indicate that a
Moissanite is detected instead.

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 if any doubt exists
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 off.

• 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.

Fig. 2.3

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.

16

4. TAKING CARE of your Presidium Multi Tester III

• The probe and wire tip is extremely sensitive and

should be handled with care, especially during the
removal of the protective cap from the pen tip. Always
replace the protective cap of the pen tip when the
probe is not in use. Caution should be taken so as
not to damage the probe and wire tip.

• Do not leave worn out batteries in the battery

compartment as the batteries may corrode, leak or
damage the tester. Batteries should be removed
when the tester is expected to be stored for an
extended period of time.

Your tester is a product of extensive design and
craftsmanship and should be treated with care.

Thank you for taking time to go through the user
handbook which will enable you to understand your
recent purchase better.

图 1.5

如果连续 10 分钟不工作，检测仪将自动关闭。

25

校准

所有检测仪在制造过程中都经过校准，不需要对检测仪作
进一步调整或用户干预。

推荐的检测条件

宝石接受检测前应清洁干燥。但是通常不必执行复杂的清
洁程序（图 1.6）。

图 1.6

建议的检测温度为 18°C – 27°C（65°- 80°F）。在
检测前请让宝石调整至室温。在室温范围外暴露和/或操
作检测仪都会影响检测结果和检测仪的性能。

电池信息

切勿将用完的电池留在电池匣内，因为电池电解液可能出
现泄露，从而腐蚀或损坏检测仪。如果预计要将检测仪存
放较长时间，应取出电池。

为防止读数误差，请在低电量指示灯亮起或开始闪烁时尽
快更换新电池。当电池的电量低或微弱时，不应执行检
测。

在使用交流适配器时不必取出电池。

在检测前清洁宝石

准备一张干净的绵纸。用镊子小心地夹起宝石，将它的切
平面朝下放在纸上（图 1.7）。

26

图 1.7

将宝石切平面抵住绵纸/首饰布轻轻擦拭（图 1.8）。

图 1.8

27

2. 在 Presidium Multi Tester III 上执行检测

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。

对于已镶嵌的珠宝或宝石：

对于已镶嵌的珠宝或宝石：
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
面的橡皮防滑把手处。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

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）。

图 2.2

关于使用 Presidium Multi-Tester III 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。
执行检测时应该让宝石的切平面朝下。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
橡皮垫处。

28

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。

如果对显示的检测结果有任何疑问，建议用户获取多次检
测读数。

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，使笔尖与任何纸张或宝石托（检测
仪附带）成直角（90 读）。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。
