5. Setup Instructions
- Prepare Mounting Location: Identify a suitable location for embedding the digital thermometer display unit. Ensure the embedding hole dimensions (45.5 x 26 mm) are met.
- Install Display Unit: Carefully insert the digital thermometer display unit into the prepared embedding hole. Ensure it is securely seated.
- Connect Temperature Sensor: Connect the K-type thermocouple sensor to the designated input terminals on the back of the display unit. Observe polarity if indicated (typically red for positive, blue for negative, or as marked on the device).
- Mount Temperature Sensor: Install the M6 threaded K-type temperature sensor at the point where temperature measurement is required. Ensure good thermal contact for accurate readings.
- Connect Power Supply: Connect a DC 12V ±2V power supply to the power input terminals of the display unit. Pay close attention to polarity (red for positive, black for negative). The device features reverse connection conservation, but correct connection is always recommended.
- Verify Connections: Double-check all connections to ensure they are firm and correctly polarized before applying power.

6. Operating Instructions
- Power On: Once all connections are secure and verified, apply power to the DC 12V input. The LED display will illuminate.
- Initial Reading: The display will show the current temperature measured by the K-type thermocouple sensor. Allow a few moments for the reading to stabilize.
- Temperature Monitoring: The thermometer continuously monitors and displays the temperature. The refresh rate is approximately 4 times per second.
- Reading Interpretation: The displayed value is in degrees Celsius (℃). Ensure the temperature is within the specified range of -30℃ to 800℃.
- Power Off: To turn off the device, disconnect the DC 12V power supply.

7. Maintenance
- Cleaning: Regularly wipe the display unit with a soft, dry cloth. Avoid using abrasive cleaners or solvents, as these can damage the display or casing.
- Sensor Inspection: Periodically inspect the K-type thermocouple sensor for any signs of damage, corrosion, or wear. Ensure the M6 thread connection remains secure.
- Environmental Conditions: Ensure the thermometer is operated and stored within appropriate environmental conditions to prevent damage from extreme temperatures or humidity.
- Power Supply: Use only a stable DC 12V ±2V power supply to prevent electrical damage.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display when powered on. | No power, incorrect power connection, or faulty power supply. | Check power supply (DC 12V ±2V). Verify power cable connections and polarity. Ensure the power source is active. |
| Inaccurate temperature readings. | Poor sensor contact, damaged sensor, or sensor not properly connected. | Ensure the K-type thermocouple sensor has good thermal contact with the object being measured. Check sensor cable connections for looseness or damage. Replace sensor if damaged. |
| Display shows "---" or error code. | Sensor disconnected, open circuit in sensor, or temperature out of range. | Verify sensor connection. Check if the measured temperature is outside the -30℃ to 800℃ range. If the sensor is damaged, replace it. |
| Display flickers or is unstable. | Unstable power supply or strong electromagnetic interference. | Ensure a stable DC 12V power supply. Relocate the device away from strong electromagnetic fields. |
