How to use

Insert the 1.5 V battery according to the polarity markings, then switch the thermometer on. Select the preferred temperature unit if applicable. Insert the stainless steel probe into the food or liquid until the sensing tip reaches the center of the item being measured, taking care to avoid contact with bone or container walls for an accurate reading. Read the temperature from the illuminated display; typical response time is a few seconds. After use, wipe the probe clean with a damp cloth or sanitizing wipe and allow it to dry before storing.

Usage recommendations

For reliable results, calibrate or verify the thermometer periodically against a known reference (ice bath for 0 °C or boiling water for approximately 100 °C at sea level). Avoid immersing the display or battery compartment in water. When measuring high-temperature items, take care to protect hands from heat and ensure the probe tip is fully inserted into the thickest part of the food for an accurate internal temperature.
