6.1 Powering On/Off

• To turn on the thermometer, press the ON/OFF button.
• To turn off the thermometer, press the ON/OFF button again. The thermometer will automatically shut off after a period of inactivity to conserve battery life.

6.2 Measuring Temperature

1. Remove the protective probe sheath.
2. Insert the stainless steel probe into the thickest part of the food, avoiding bone or gristle. Ensure the probe tip is fully immersed.
3. Wait for the temperature reading on the LCD display to stabilize. This usually takes a few seconds.
4. Once the desired temperature is reached, remove the probe from the food.
5. Clean the probe immediately after use.

6.3 Switching Temperature Units (°F/°C)

To switch between Fahrenheit (°F) and Celsius (°C), press the °F/°C button located on the front of the thermometer.

6.4 Calibration

The PS100 thermometer features a calibration function to ensure accuracy over time. For best results, calibrate the thermometer using an ice bath:

1. Fill a glass with crushed ice and add cold water until the glass is full. Stir the mixture for a few minutes.
2. Insert the thermometer probe into the ice bath, ensuring the tip is fully submerged and not touching the bottom or sides of the glass.
3. Wait for the reading to stabilize. The temperature should read 32°F (0°C).
4. If the reading is not 32°F (0°C), press and hold the CAL button for a few seconds until the display adjusts to 32°F (0°C).
5. Release the CAL button. The thermometer is now calibrated.

7. Maintenance and Care

7.1 Cleaning

• The thermometer probe should be cleaned with hot soapy water or an antibacterial wipe after each use.
• The main unit is water-resistant, meaning it can withstand splashes and brief exposure to moisture. Do not submerge the entire unit in water or wash it in a dishwasher.
• Wipe the body of the thermometer with a damp cloth.
• Ensure the thermometer is completely dry before storing.

7.2 Storage

• Always store the thermometer with the protective probe sheath in place to prevent damage to the probe and for safety.
• Store in a clean, dry place at room temperature.

7.3 Battery Replacement

Replace the battery when the display becomes dim or the thermometer fails to power on. Follow the battery installation steps in Section 5.

8. Troubleshooting

• No Display / Dim Display: Check battery installation. Replace the battery if necessary.
• Inaccurate Readings: Perform a calibration using an ice bath as described in Section 6.4. Ensure the probe is inserted correctly into the food.
• Slow Readings: Ensure the probe tip is fully immersed in the food and not touching bone or gristle.
• Thermometer Not Turning On: Ensure the ON/OFF button is pressed firmly. Check battery.
