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 an accidental dropping of the unit. 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. One of the User's "bare" fingers must be touching the rear metal plate.· 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.· 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."DIAMOND TESTING" 1. Choose either: (A) the LARGE (normal) stone position when testing stones .08 Carat or larger (move the LARGE/SMALL STONE switch to the right). (B) the SMALL stone position when testing stones .08 Carat or smaller (move the LARGE/SMALL STONE switch to the left). 2. The ambient temperature should be between 65 F and 95 F for testing.3. Hold the diamond tester in your hand so that your fingers are in contact with the conductive panel (6). 4. With the other hand hold the stone to be tested by its setting. 5.

MIZAR Prestige Series II CZ and Diamond Tester1 year Manufacture WarrantyThe following info is directly from the Manufactures item manualPrestige 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 PARTS1. Probe2. Range Indicator3. Auto/Manual Range Adj.4. Wait/Low Battery Lamp5. Battery Compartment6. Conductive Panel7. Testing Platform for Loose Stones8. "ON" Button9. "OFF" ButtonOPERATIONAL CHECKOUT1. 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-OFFThe 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.
