The thermometer supports both Celsius (℃) and Fahrenheit (℉) units. The unit can be switched using the fine-tuning temperature buttons located on the back of the module (refer to Figure 5). Pressing the button will toggle between the two units.
5. నిర్వహణ
To ensure optimal performance and longevity of your digital thermometer, follow these simple maintenance guidelines:
- శుభ్రపరచడం: Wipe the display and module casinమృదువైన, పొడి గుడ్డతో జి. రాపిడి క్లీనర్లు లేదా ద్రావకాలను ఉపయోగించకుండా ఉండండి.
- ప్రోబ్ కేర్: Keep the NTC waterproof probes clean. If used in liquids, rinse them with clean water after use and dry thoroughly.
- నిల్వ: When not in use for extended periods, store the thermometer in a dry environment within its specified working temperature and humidity ranges.
6. ట్రబుల్షూటింగ్
This section addresses common issues you might encounter with your digital thermometer.
6.1 No Display / Incorrect Readings
- శక్తిని తనిఖీ చేయండి: Ensure the power supply is connected correctly and provides a stable DC voltagఇ 4V మరియు 28V మధ్య.
- వైరింగ్: Verify that all wires, including the power supply and probe leads, are securely connected to their respective terminals. The device has reverse connection protection for the power input, but incorrect probe wiring can lead to no readings or erratic behavior.
- ప్రోబ్ ప్లేస్మెంట్: Ensure the NTC probes are properly immersed or placed in the environment where temperature is to be measured.
- పర్యావరణ పరిస్థితులు: Confirm that the working temperature and humidity are within the specified ranges (-10~+65 ℃, 10~80% humidity without condensation).
6.2 సరికాని రీడింగ్లు
- దర్యాప్తు పరిస్థితి: Inspect the NTC probes for any physical damage or corrosion. A damaged probe may provide incorrect readings.
- జోక్యం: Ensure the probes and wiring are not exposed to strong electromagnetic interference, which could affect accuracy.
- క్రమాంకనం: While the device is factory calibrated, significant discrepancies might require professional recalibration or replacement of probes.
7 వినియోగదారు చిట్కాలు
- For the most accurate temperature readings, ensure the NTC probes are fully immersed in liquids or have good thermal contact with the surface/medium being measured.
- When measuring temperatures in different environments (e.g., car interior and exterior, or different sections of a refrigerator), position the probes strategically to get representative readings.
- Utilize the ℃/℉ switchable feature to display temperatures in your preferred unit.
