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.
1. Perform the operational checkout as described above.
2. The twelve lamp
Auto/Manual Range Indicator is segmented as follows: 
3. The ambient temperature should be between 70°F and 88°F for "Auto"
Testing. Normally Lamp #3 will be lit.
4. Hold the diamond tester in your
hand so that your fingers are in contact with the conductive panel (6).
5.
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.
6. Guide the probe tip to the center of a facet on the stone.
7. 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.
8. Make sure the probe is perpendicular to facet of stone while
testing.
9. After each test the display should return to the original
lamp.
MANUAL TESTING RANGE
Manual testing can be used under all conditions (temperatures and stone
size).
Before testing a stone set the Range Indicator (2) to the correct
calibration position with the Range Adj. (3). The correct position is selected
from the calibration chart below. Selection of the calibration is based on the
stone size and surrounding temperature.
Under 0.06ct., set the Range Indicator Lamp to light on up to 6.
From
0.06ct. to 0.5ct, set the Range Indicator Lamp to light up to 4.
Over 0.5ct.,
set the Range Indicator Lamp to light on up to 2.
For example, when testing a
stone of about 0.3 carat in colder
temperatures, set the Range Indicator
Lamp to light on 3 and in warmer
temperatures set it to light on 5.
HELPFUL HINTS
· If the red Low Battery lamp remains on after twenty seconds replace
battery.
· Stones being worn, which may be well above room temperature can be
tested immediately using the manual mode. Simply set the range set point one
lamp number greater than what the calibration chart indicates or allow the stone
to return to room temperature before testing.
· When testing a small stone
avoid incidental heating of the stone by the probe; make good contact against
the stone on the first test attempt, otherwise allow the stone to return to room
temperature before retesting.
· Observation of display activity allows user
to determine a number of things: a) Diamonds cause rapid "movement up the
display" and large diamonds "move all the way to lamp eleven quickly. b) Cubic
Zirconias hardly "move up the display" at all. c) Other semi-precious gems
consistently "move up the display" various "distances" based on their size. d)
The only stone that comes close to reading as a diamond is the large sapphire or
ruby (corundum). It "moves up the range" very slowly compared to diamond and the
slow movement is a further indication of sapphire. Also the kind of color
usually allows easy rejection of colored sapphires. Large white sapphires can
approach the diamond range but these stones can easily be rejected because they
do not "sparkle" as diamonds do under normal incandescent lighting.
INTERPRETING THE INDICATION
METAL ALERT - The sounding of a continuous audible tone indicates that the
probe tip is in contact with either the users hand, the setting, or the testing
platform. The "Tone" is also accompanied by the display being momentarily turned
off. The remedy is to reposition the probe tip as described under "Auto" Test
section.
DIAMOND SIMULANTS - When testing Cubic Zirconiums, "Paste", Strass
and other diamond simulants no illumination of the green diamond lamp will be
observed. However, some diamond simulants may light one yellow lamp beyond the
initial set point.
DIAMONDS - Testing of a genuine diamond will cause the
green diamond lamp to flash (along with the red error light) and a discontinuous
beeping will sound.
MAINTENANCE
· Always place the protective cover over the probe immediately
after use. Probe tip damage is not covered in the warranty.
· The only
maintenance required is: (1.) cleaning the probe tip and (2) battery
replacement.
