Congratulations on your purchase of the Prestige Series II,

the world's finest diamond tester. With this unique

Instrument you will obtain the most information about the

stones you are testing. You also will have the versatility

of selecting between the "auto" mode with valuable

sensitivity or the "manual" mode which allows for

adjustments for extremes in temperature or stone size.

IDENTIFICATION OF PARTS

1. Probe

2. Range Indicator

3. Auto/Manual Range Adj.

4. Wait/Low Battery Lamp

5. Battery Compartment

6. Conductive Panel

7. Testing Platform for Loose Stones

8. "ON" Button

9. "OFF" Button

*PRIOR TO TESTING, IT IS RECOMMENDED THAT THE

TIP OF THE PROBE BE CLEANED BY GENTLY WIPING

ACROSS A CLEAN SHEET OF PAPER *

OPERATIONAL CHECKOUT

1. Rotate the Thumbwheel (3) in a counter-clockwise

direction beyond the "click".

2. Press the "ON" button (8).

3. The Wait Lamp (4) will be lit.

4. All other display lamps will remain extinguished for

the wait period, which is typically less than nine

seconds at room temperature. The time can increase

with low temperatures or a weak battery. After the

wait period there is a single beep.

5. If the waiting time exceeds twenty seconds or the Wait

Lamp fails to extinguish replace the battery.

6. The Diamond Tester is ready to use after the Wait Lamp

extinguishes and a display lamp (#1 to #8) is lit. In the

"Auto" mode display lamp 3 is normally lit after the

unit has warmed up, typically ten to twenty seconds.

7. If the ambient temperature is not within the range of

the automatic circuitry (70-88 F, 21-31 C) the diamond

tester is still able to test a stone by testing with the

Manual Range Adjust (3).

8. When testing is completed press the "OFF" button.

Always turn off the unit after testing to increase

battery life.

"AUTO-SET"

This adjustment affects the sensitivity of the "automatic

range" only. It is pre-set at the factory to lamp #3. If you

prefer a higher sensitivity for diamonds you may adjust

the "auto-set" (through the bottom of the front label) to

lamp #4. To make this adjustment, turn the thumbwheel

(3) fully counter-clockwise until clicked. Turn the unit on

and wait twenty seconds to allow the probe to reach

maximum temperature. Then with a jeweler's screwdriver

adjust the "Auto-Set" to "the center of" lamp #4. If you

prefer a lower sensitivity follow the above procedure and

adjust to "the center of" lamp #2.

This adjustment will

not affect the Manual mode.

AUTOMATIC SHUT-OFF

The Diamond Tester will automatically shut off after 90

seconds of inactivity. Whenever the "On" button is

pressed the timer resets to 90 seconds. If the unit is shut

off before you have completed your test simply press the

on button and continue your testing as soon as the

display comes on. Always press the "OFF" button after

testing to prolong battery life.

PREPARATION PRIOR TO TESTING A STONE



The presence of dust, dirt, film and moisture on a stone may produce an inaccurate indication. Therefore, it is

prudent to routinely clean the surface of each stone to be tested by using a damp soft clean fabric followed by

drying using a dry soft clean fabric.



Remove the protective cover from the probe.



The tip of the probe should be cleaned frequently by wiping the tip across the surface of a piece of bonded

paper or a business card. Copier paper and fax paper are to be avoided.



The tip of the probe may be damaged by accidental drop. Always place the protective cover over the probe

immediately after use. Probe tip damage is exempted from the warranty.



During testing the users hands should be clean and dry. Do not wear gloves.



The stone to be tested should be allowed to reach room temperature.



For maximum accuracy, minimize handling of the stone prior to testing. If the item to be tested consists of a

setting containing many stones requiring more than ten seconds to test user must avoid heating the setting

with his hand; allow the item to be untouched for about fifteen seconds.



Loose stones may be placed on the testing platform (9) at any time and be tested immediately.



Best results are obtained by performing tests in still air. Avoid fans, drafts or air movement from air

conditioning or heating sources. Avoid breathing directly on the probe tip while testing.

"AUTO" TESTING

"Auto"-Testing can be performed when the temperature is within 70-88 F and the stone size is between .08 and .75

Karats. For all other conditions use the manual mode and adjust to the calibration chart (p.3). The automatic testing

mode ("Auto"-Testing) is achieved by rotating the thumbwheel counter-clockwise until a "click" is felt.

Perform the operational checkout as described above.

The twelve lamp Auto/Manual Range Indicator is segmented as follows:

The ambient temperature should be between 70F and 88F for "Auto" Testing. Normally Lamp #3 will be

lit.

Hold the diamond tester in your hand so that your fingers are in contact with the conductive panel (6).

With the other hand pick up the stone to be tested by its setting or place a loose stone in the appropriate

well in the testing platform held with that hand.

Guide the probe tip to the center of a facet on the stone.

Touch the probe tip to the stone so that the probe tip is firmly and squarely against the facet of the

stone. Excessive force which might bend or break the tip must be avoided.

Make sure the probe is perpendicular to facet of stone while testing.

After each test the display should return to the original lamp.

10.

As always some stones require further testing to determine what they are. In the case of some

Moissanite Stones especially the "Forever One" Moissanite stone try using UV lignt on the stone while

testing will help like the ones used for counterfeit money e.t.c.
