3. Operating Instructions
3.1 Taking a Temperature Reading
- Unfold the probe to turn on the thermometer.
- Insert the stainless steel probe into the thickest part of the food, avoiding bone or gristle.
- The temperature will display on the LCD screen within 2-3 seconds.
- For optimal accuracy, ensure the probe tip is fully inserted into the food.
3.2 Using the HOLD Function
Press the 'HOLD' button to freeze the current temperature reading on the display. This is useful when you need to remove the thermometer from the food to read the temperature more clearly. Press 'HOLD' again to resume live temperature readings.
3.3 Finding the Thermal Center (for thick cuts)
For accurate readings in thick cuts of meat, push the probe past the suspected center, then slowly pull it back. The lowest temperature displayed during this process indicates the thermal center of the food.

4. Maintenance and Care
4.1 Cleaning Instructions
The Smak DT-68 thermometer is waterproof, allowing for easy cleaning. However, it is recommended to hand wash only the probe and avoid completely immersing the entire unit in water for extended periods. Wipe the body with a damp cloth. Do not place in a dishwasher.
4.2 Storage
The thermometer features a folding probe for safe and compact storage. It also has a built-in magnet for attachment to metallic surfaces (like a refrigerator or grill side) and a hanging hole for convenient storage on hooks.

5. Troubleshooting
5.1 Device Does Not Turn On
- Ensure the probe is fully unfolded.
- Check the battery. Replace the CR2 battery if it is depleted or incorrectly installed.
5.2 Inaccurate Readings
- Ensure the probe is inserted into the thickest part of the food, away from bones.
- Allow sufficient time (2-3 seconds) for the reading to stabilize.
- Perform a calibration check using ice water (0°C / 32°F) or boiling water (100°C / 212°F at sea level). If the reading is off, the thermometer may require recalibration or battery replacement.
