"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
