Instructions for Use

1. Handling and Storage:

   • Store in a dry, cool place away from direct sunlight.
   • Handle with care to avoid mechanical damage.

2. Mounting:

   • Solder the leads to the PCB using a temperature-controlled soldering iron.
   • Ensure the soldering temperature does not exceed 350°C to prevent damage.
   • Allow the thermistor to cool naturally after soldering.

3. Electrical Connections:

   • Connect the thermistor in series or parallel as required by your circuit design.
   • Use appropriate wire gauge to minimize resistance and ensure reliable connections.

4. Temperature Measurement:

   • Use the resistance-temperature relationship to determine the temperature.
   • The resistance can be measured using a multimeter or an analog-to-digital converter (ADC).

5. Calibration:

   • Calibrate the thermistor using known temperature points to ensure accuracy.
   • Use the beta value and nominal resistance to calculate the temperature based on the measured resistance.

6. Environmental Considerations:

   • Avoid exposing the thermistor to environments with high humidity or corrosive gases.
   • Ensure proper ventilation if used in enclosed spaces.

7. Testing:

   • Test the thermistor in a controlled environment to verify its performance.
   • Compare the measured resistance values with the expected values for different temperatures.

8. Troubleshooting:

   • If the thermistor does not provide accurate readings, check for loose connections, damaged leads, or contamination.
   • Replace the thermistor if it shows signs of physical damage or inconsistent readings.
