8. Applications
The TOOLTOP ET14C is suitable for a wide range of applications, including:
- Home appliance overhaul
- Circuit board inspection
- Power supply and electronic equipment maintenance
- HVAC pipe testing
- Floor heating leak detection
- Power company inspection
- Industrial temperature measurement

8.1 Floor Heating Leak Detection
Follow these steps for effective floor heating leak detection:
- Pressurize the various branches of underfloor heating.
- Inject hot water into the leaking branch of the underfloor heating system.
- Check the condition of the underfloor heating system in 20 minutes.
- Use the thermal imaging instrument with emissivity set at 0.9-0.95.
- Identify temperature anomalies/leaks along the route.
- After finding the leakage point, open the floor tile for repair.

8.2 Circuit Board Inspection
For detailed circuit board inspection, especially with the macro lens:
- Slide the macro lens onto the thermal imaging lens.
- Align the thermal imaging device with the components that need to be tested.
- The best measurement distance is 2.5 centimeters.
- The temperature at the short-circuit point is higher than the surrounding color, making it brighter.
- The color of the circuit breaker point is dark or even not shiny.

11. Maintenance
- Cleaning: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners or solvents.
- Storage: Store the device in its protective storage bag in a cool, dry place when not in use.
- Battery Care: If storing for extended periods, remove the battery and store it separately. Recharge the battery periodically to maintain its health.
12. Troubleshooting
12.1 Image Lag During Calibration
Issue: The thermal image experiences a lag of about 1-2 seconds periodically.
Solution: This is a normal phenomenon. The device includes a mechanical control calibration plate in front of the thermal imaging detector. It performs non-uniformity correction every 10 seconds to ensure accurate measurements. This brief lag is part of the calibration process and does not indicate a malfunction.
13. User Tips
- For precise PCB circuit board inspections, it is highly recommended to use the version of the ET14C that includes the macro lens.
- When using the macro lens, ensure the device is held approximately 2.5 cm from the target for the clearest image.
- Regularly check and adjust the emissivity setting based on the material being measured to ensure the most accurate temperature readings.
