6. Выпраўленне непаладак

If you encounter issues with your XGZP6897D sensor, consider the following troubleshooting steps:

• No Output/Incorrect Readings:
  • Праверце блок харчавання voltage (VDD) is within the specified range (e.g., 5Vdc or 3.3Vdc depending on model).
  • Check all electrical connections for proper contact and continuity.
  • Ensure N/C pins are floating and not inadvertently connected.
  • Confirm the 0.1µF capacitor is correctly installed between VDD and GND.
  • Check if the pressure medium is non-corrosive and compatible with the sensor.
  • Ensure pressure ports are correctly connected (Port 1 high, Port 2 low).
• Unstable Output:
  • Check for electrical noise in the system; consider additional filtering if necessary.
  • Пераканайцеся, што электразабеспячэнне стабільнае і без ваганняў.
  • Verify the operating temperature is within the compensated range.
• Пашкоджанне датчыка:
  • Inspect for physical damage to the sensor housing or pins.
  • Recall if the sensor was exposed to over-voltage, over-current, or incompatible media.
