Accuracy, on the other hand, refers to how close a measured value is to the true or actual value of the jewelry's composition. For a Jewelry Checking Machine, this means if a piece of gold is genuinely 18K (75% gold), an accurate machine will report a value very close to 75.0%. VRAY Jewelry Checking machines boast impressive accuracy specifications, such as 0.1% for gold (VR-X5) and 0.003 for 9999 gold (VR-H5, VR-S7). This exceptional accuracy is achieved through the integration of advanced technologies like high-performance Si-PIN proportional detectors (in VR-X5) and customized Si-PIN detectors (in VR-H5, and US-sourced in VR-S7), which precisely capture the characteristic X-ray signals. Furthermore, our machines utilize a stable PDT (50 KV) full mirror-focused tungsten X-ray tube and a precise Φ0.8mm collimator, ensuring optimal excitation and targeted analysis. The stable operating environment, supported by dedicated T-shaped heat dissipation without external cooling, also contributes to consistent detector performance. Achieving high accuracy is paramount in the jewelry industry to prevent misrepresentation, ensure fair trade, and provide correct valuations for precious metals. While precision indicates reproducibility, accuracy confirms the measurement's validity against the true composition, minimizing systematic errors and ensuring reliable identification of metal purity and type.
Operating a VRAY Jewelry Checking Machine is a straightforward process designed for efficiency and accuracy. Follow these steps for proper usage:
Power On: Turn on the machine and then open its dedicated software application.
Instrument Preheating: Allow the instrument to preheat for approximately 10 minutes. This stabilizes the internal components for accurate readings.
Calibration: Place the designated calibration sample in the detection area and perform the instrument calibration as prompted by the software. This ensures measurement accuracy.
Sample Placement: After successful calibration, carefully place the actual jewelry sample you wish to analyze into the detection area.
Initiate Test: Close the machine's cover securely and press the "start" button to begin the analysis.
Await Results: The machine will now perform the analysis. Generally, a preliminary analysis result will be displayed within 3 seconds, with the complete, final analysis result available in approximately 30 seconds.
Print/Save Report: Once the test is completed, select the "Print" icon to generate a report. You have the option to print an A4 report or use a Bluetooth thermal printer. Alternatively, you can save the report digitally without immediate printing.
Proper maintenance is crucial for ensuring the longevity, accuracy, and consistent performance of your VRAY Jewelry Checking Machine. Adhere to these routine maintenance practices:
Daily Cleaning: Wipe the outer shell of the machine with a clean, soft, or lint-free cloth every day to prevent the accumulation of dust and debris.
Test Window Inspection: Before each use, visually inspect the test window (detector film) for any foreign objects, contamination, or smudges. Keep it impeccably clean and transparent to ensure accurate X-ray penetration and signal detection.
Regular Fan and Vent Cleaning: Clean the machine's fans and ventilation outlets regularly. This prevents blockages that can lead to overheating and ensures efficient cooling of internal components.
Environmental Control: Maintain the room temperature between 15-30°C and humidity below 70%. Avoid exposure to excessive moisture or direct sunlight, as these conditions can negatively impact the sensitive electronics.
Voltage Stability: Always use a voltage stabilizer or an Uninterruptible Power Supply (UPS) to protect the machine from unstable voltage, which can damage critical components like the X-ray tube and motherboard.
Avoid Prolonged High-Load Use: While VRAY machines are designed for efficiency, avoid prolonged continuous high-load operation. It's advisable to allow the machine to rest periodically or turn off its internal cooling (if applicable, or simply allow internal components to cool down) after extended use to prevent overheating and prolong component lifespan.
