1. Principles and Features of the X-MET8000 Spectrometer

1.1 Working Principle

The X-MET8000 spectrometer operates based on X-ray fluorescence (XRF). When X-rays strike a material, they dislodge inner-shell electrons, creating vacancies. Electrons from higher energy levels fill these vacancies, releasing energy in the form of characteristic X-rays. By detecting and analyzing these emitted X-rays, the device can determine the elemental composition of the material.

1.2 Key Features

• Wide Element Range: Analyzes elements from magnesium (Mg) to uranium (U).
• Portability: Lightweight and rugged design for on-site measurements.
• High Accuracy: Equipped with advanced calibration options, including empirical and fundamental parameter (FP) calibrations.
• Touchscreen Interface: Intuitive controls and customizable menus.
• Battery Powered: Operates with a rechargeable battery for field use.
• Safety Features:
  • Proximity Sensor: Prevents accidental X-ray exposure.
  • X-Ray Shutter: Indicates when the X-ray source is active.

2. Usage Methods and Best Practices

2.1 Startup Procedure

1. Switching On:
   • Hold the power button for five seconds until the device powers on.
2. Login:
   • Use the default passwords: Operator (1111) or Supervisor (0000). Change passwords for security.
3. Calibration:
   • Use the factory calibration or perform a custom calibration depending on the sample type.

2.2 Measurement Procedure

1. Prepare the Sample:
   • Ensure the sample surface is clean and smooth to avoid measurement errors.
2. Position the Device:
   • Place the measurement window firmly against the sample. Ensure full coverage of the proximity sensor.
3. Take Measurements:
   • Pull and hold the trigger to activate the X-ray source. The results screen refreshes every two seconds.
   • Release the trigger once the measurement is complete.

2.3 Data Management

• Batch Mode: Average measurements from multiple samples for consistency.
• Report Generation:
  • Export results via USB, network share, or directly to a printer.

2.4 Maintenance

• Daily Cleaning: Wipe the measurement window with isopropyl alcohol.
• Weekly Maintenance: Inspect connectors, batteries, and protective films for wear or damage.
• Battery Care: Avoid overcharging to prolong battery life.

3. Troubleshooting and Error Codes

The X-MET8000 includes a robust diagnostic system to alert users to errors. Below are some common error codes, their meanings, and potential solutions.

3.1 Common Error Codes

Error Code	Meaning	Possible Causes	Solutions
ID-14	Proximity sensor not detecting a sample	Sample not fully covering the window, sensor malfunction	Clean the sensor, ensure proper sample placement, or replace the sensor.
ID-07	Low battery	Battery voltage too low	Recharge or replace the battery.
ID-21	Calibration error	Incorrect calibration settings or sample mismatch	Recalibrate using the correct method or replace the reference sample.
ID-30	Detector error	Issues with the X-ray detector, such as contamination or damage	Inspect and clean the detector; contact technical support if needed.

3.2 ID-14 Error: In-Depth Analysis

The ID-14 error occurs when the sample proximity sensor fails to detect the sample, causing the device to halt measurements. This can result from:

• Improper Sample Placement: The sample does not fully cover the sensor or has an irregular surface.
• Sensor Contamination: Dust, oil, or debris on the sensor blocks detection.
• Hardware Failure: Issues with the infrared emitter or receiver in the sensor.

Solution:

1. Inspect the sample for proper placement and cleanliness.
2. Clean the proximity sensor with a lint-free cloth and isopropyl alcohol.
3. Test the sensor using a multimeter or infrared camera. Replace if necessary.

   • Ensure the device is not pointed at people or animals during operation.
   • Use only in accordance with local X-ray safety regulations.
2. Avoid Misuse:
   • Do not operate the spectrometer with a damaged proximity sensor or X-ray shutter.
3. Store Properly:
   • Keep the device in a dry, dust-free environment when not in use.
4. Use Genuine Accessories:
   • Only use approved batteries, chargers, and protective films to avoid device damage.
