 DIAMOND MATE

The PERSIDUM Diamond Mate has developed to distinguish between a diamond and its stimulant, it makes use of the fact that a diamond Conducts heat better than any known diamond stimulant material. Other properties of diamond, such as its high refractive index, can be closely matched by other materials and they are therefore less useful in identifying this most precious gemstone.

The PERSIDUM Diamond Mate utilizes the same patented principle and basic design of electronic circuitry as all of its predecessors. The Heat Tip consists of two linked thermometers, one of which is heated electrically while the other is cooled by gemstone being tested. The difference between the temperatures of two thermometers is a measure of the heat conductivity of the gemstone and gives rise to an electrical output that is amplified on a LED level mater. The meter reading thus indicates the heat conductivity.

Features:

1.1 NO waiting time between test, the recovery time after each test is approximately 2 seconds, the tester can be used continuously without the need to stop.

1.2 Available in two models:

a) For model: Diamond Mate-A –it operates on 3 X AAA /IR03/ AM4 alkaline batteries or directly from an electrical outlet (200V/ 110v ac) with an AC adapter. (AC adapter and alkaline batteries for this model).
b) For model: Diamond Mate-B –it operates on 3 X Nicad rechargeable batteries or directly from an electrical outlet (220V / 110V ac) with an AC adapter, (Batteries and AC adapter/ charger are included for this model).

1.3 Pocket size- measuring only 160 X 30 X 20.5 mm.

1.4 Low batteries indicator- a small red light will appear to indicate low batteries.

1.5 Metal detector- an audible intermittent deep will alert the user when the probe tip is in contacted with any metal.

1.6 Measured diamond- the LED level meter will instantly light up to the green zone the same time an audible continuous deep will alert the user of a successful test.

1.7 Low battery consumption- the alkaline batteries in the “Diamond Mate-A” will last 3 times longer than any other diamond testers in the market.

Preparing the Presidium Diamond Mate for use:

2.1 a) Model: Diamond Mate-A this Model operates on 3 X AAA alkaline batteries, simply insert the batteries , simply insert the batteries into the battery compartment of the instrument and note + symbols, only alkaline batteries should be used to optimize the life of your instrument, This model was tested to operate continuously for 7 hours using alkaline batteries, it also operates efficiently using an AC adapter connected directly to a suitable electrical outlet, use only the adapter (optional) supplied by the manufacturer.
b) Model: Diamond Mate –C when you receive the instrument from your dealer, the NICAD batteries will need to be charged for 6-8 hours prior to use, simply insert the AC adapter/Charger (supplied with this model) into a suitable electrical outlet, while operated as normal via the AC source without any interference, A fully charged Nickel cadmium batteries will operate the instrument continuously for 2 hours.

2.2 Switch on the unit and wait for a bout 25 seconds to warm up the instrument, while in this preparation mode, a green light will blink continuously the light will stop blinking when is “ READY” to be used.
2.3 Use just enough pressure to depress the protruding probe tip at right angle to the facet of the stone until it retracts completely into the housing, this will result in the lighting up of the red LED when a stimulant is being tested and the green LED with a continuous audible beep when a diamond is being tested.
2.4 The PRESIDIUM DISMOND has been completely calibrated in the factory and no further adjustment/calibration is required.
2.5 This unit comes with an auto power down feature.

 

How to perform a test with your Diamond Mate:

3.1 Prepare your gemstone and testing must be done at room temperature, Hold the unit at approximately right angle to the facet of the gemstone that you are going to test, Apply just enough pressure to the probe to allow it to retract completely into the housing, with the fully retracted probe, it will automatically maintain a steady and constant contact between the probe and the facet of the gemstone where the measurement is taking place.
3.2 The LED will display the test result instantly with the lights rising rapidly to its maximum value within one or two seconds and thereafter it will fall gradually.
3.3 If the reading reaches the green zone, an audible continous beep will activate signalizing that a diamond is being identified and if the light stopped at any red zone, a stimulant is being identified.

Note: This instrument can also be used as an aid to distinguish some known stimulant (colour stone) such as:

Sapphire vs Tanzanite
Sapphire vs Iotite
Sapphire vs Spinel

Sapphire vs Topaz
Sapphire vs Glass


However further examination is recommended for final analysis of stimulant
3.4 When the probe is in contact with any metal detector . your fingers must be in contact at all time with the metal plated serrated parts conveniently located on both sides of the tester. This user friendly feature wads designed in such a way that most user’s fingers will automatically be contact with the serrated components.


Important notes.


4.1 The gemstone must be clean and dry before testing, elaborate cleaning procedures are not necessary . The tip of the tester probe must also be clean to ensure proper contact with the gem. It is a good habit to rub the probe tip gently a Crosse a bond paper surface before testing and do it periodically.
4.2 For accurate testing, the instrument must be operated at room temperature (65-80◦F/18-27◦C) Prior to any testing ,always allow the gems/ jewellery pieces to adjust to room temperature.
4.3 For testing of very small diamonds (10 points and below ) the LED on the green zone may not light up its maximum range. It is not uncommon to have only one green light lighted up. For measuring small loose stones , it is advisable to use a stone try ( optional) to achieve optimum accuracy
4.4 Change batteries or recharge the batteries as soon as the low battery indicator light appears.
4.5 The PRESIDIUM DLAMONDMATE has undergone thorough and extensive laboratory tests and checks. Ii will give a clear and reliable indication of whether or not a particular gemstone is a diamond or otherwise.
4.6 Under no circumstances shall PRESIDIUMINSTRUMENT PTELID, the manufacturer, or any of its distributors be liable for Direct or Indirect Damages Sustained Connection with the PRESIDIUM DLAMONDMATE.

Maintenance

5.1 The probe tip of the instrument is very delicate and it should be handled carefully.
One must exercise caution when removing the protective cap so as not to damage the tip. When the instrument is not in use, always replace the cap to protect to the probe tip.
5.2 One must stop suing the instrument when the low battery indicator is lighted up. This is to prevent any inaccurate measurements.
5.3 Do not leave batteries in the battery compartment as they may corrode and cause damage to the instrument is to be stored for an extended period of time.
5.4 I is advisable to have the instrument serviced calibrated once a year.
