OPERATING INSTRUCTIONS FOR THE CERES CZECKPOINT XL DIAMOND TESTERCongratulations on purchasing the new CZeckpoint XL, the latest generation diamond tester from Ceres Electronics Corporation, the pioneer in electronic gemological products. The CZeckpoint XL is rugged and simple to operate and will provide years of service, provided that these instructions are followed carefully. Failure to read this manual carefully and follow its instructions could lead to improper identification of gemstones and/or to damage to the product. HOW IT WORKSOne of the properties unique to natural diamond is the ability to conduct heat very rapidly. All common diamond simulants such as Glass and Cubic Zirconia are typically poor conductors of heat. Ceres Electronics was first to recognize the importance of this significant difference in thermal conductivity as a practical, simple method of gem identification. The thermal gem-testing technique, developed and patented by Ceres Electronics, is now universally accepted by gem and jewelry professionals. WHAT IT CAN AND CANNOT DOThe CZeckpoint XL has been designed to assist the professional jeweler and gemologist who can visually identify older diamond simulants such as YAG, Sapphire, or Titanite, but who may have some difficulty in spotting CZ gems, particularly smaller stones set in gold or silver. For this purpose the CZeckpoint XL provides a fast, reliable, and universally accepted method to confirm the user's judgment. While Ceres thermal conductivity testers have been proven themselves as inexpensive and practical aids to identify diamond-like gems, positive identification should be confirmed by the use of more sophisticated methods of evaluation, coupled with the experienced skills and judgment of the user. The CZeckpoint XL is not intended to identify Moissanite. For proper identification of Moissanite, the user must use the CZeckpoint XL in tandem with the Ceres Secure II Moissanite Detector. PERFORMING A TESTRemove the protective cover from the probe tip and move the power switch from the Off to the On position. The Red (READY) light will flash for approximately 15 seconds as the probe tip is warmed up. At the conclusion of the warm-up period, the READY light may go out very briefly, but the READY light will reilluminate and will remain on, and you will hear a short beep. The CZeckpoint XL is now ready to operate. To perform a test, place the probe tip squarely against the facet of the gemstone, using sufficient pressure for the spring-loaded metal tip to retract partially into its plastic housing. Press firmly and quickly, but do not press so hard that the probe tip retracts fully into the housing. FEATURESMetal Warning Buzzer The CZeckpoint XL incorporates a Warning Buzzer indicating that the probe tip has come in contact with metal. Since gold and silver share diamond's high thermal conductivity, many diamond testers provide a diamond reading when you are actually touching the metallic setting of CZ jewelry. For proper operation of the Warning Buzzer, you must hold the piece of jewelry in one hand while touching the CZeckpoint XL's ribbed Contact Plate with the thumb of your other hand. Although it is possible that the Green (DIAM) light could illuminate when metal is contacted, the Warning Buzzer will also sound, indicating that you must retest. Automatic Battery Shutoff The CZeckpoint XL's advanced circuitry includes a feature that will automatically turn the unit off if it has been idle for approximately 90 seconds. If the instrument has turned itself off, simply move the power switch to the Off position and then back to On to restart. REPLACING THE BATTERIESThe CZeckpoint XL operates on three "AAA" alkaline batteries. Do not use lithium-ion or nickel-cadmium rechargeable batteries in this product - use of improper batteries could cause damage and may be a fire hazard, and will void the limited lifetime warranty. The batteries will require replacement when the Red (READY) light becomes dim or goes out entirely. When this occurs, remove the old batteries and replace them with fresh ones, making sure to observe the correct battery polarity as indicated on the label inside the battery compartment. Please note that the CZeckpoint XL's battery connectors can become tarnished when the product is used under humid conditions or when the batteries are changed very frequently. If tarnishing occurs, clean the connectors with alcohol and a cotton swab. TROUBLESHOOTINGSERVICE AGREEMENTIn the event that your CZeckpoint XL is not performing to your expectations, we strongly recommend calling Ceres Electronics' Customer Service Department before returning it for repair. Many problems can be solved quickly and easily over the telephone, without the need to return the unit for service. Specifically, make sure you have cleaned the probe tip thoroughly before shipping, as this is the most common cause of improper function. WARNINGThere are no user-serviceable parts in the unit. Do not take it apart, as there are areas on the circuit that when touched will give an uncomfortable electrical shock. Evidence of tampering also voids the Limited Lifetime Warranty. WARRANTY AND DISCLAIMER CERES ELECTRONICS CORPORATION WARRANTS THAT THIS CERES CZECKPOINT XL WILL BE FREE FROM DEFECTS IN MATERIAL AND WORKMANSHIP FOR AS LONG AS YOU OWN IT. THIS WARRANTY EXTENDS ONLY TO THE ORIGINAL PURCHASER OF THIS INSTRUMENT AND DOES NOT INCLUDE THE PROBE TIP, BATTERIES, OR BATTERY CONNECTORS, WHICH ARE WARRANTED FOR TWO (2) YEARS. In the event of a defect during the warranty period, CERES ELECTRONICS CORPORATION should be notified and the purchaser should return the instrument to CERES ELECTRONICS CORPORATION, freight prepaid, properly identified, and with proof of purchase date. The sole obligation of CERES ELECTRONICS CORPORATION, after reasonable opportunity to inspect the instrument, will be to repair or replace the defective instrument, or any part of the instrument that is proven to the satisfaction of CERES ELECTRONICS CORPORATION to have been defective at the time of purchase, or that has become defective in normal use during the warranty period, at its option and at no charge to the purchaser. The above warranty is void if the instrument has been serviced by anyone other than CERES ELECTRONICS CORPORATION or has been altered, abused, misused or used for purposes other than those for which it was designed or used in a manner contrary to the unit's operators manual.
