How to Use

To use the thermometer, turn it on and off using the largest button on the side. To adjust between Fahrenheit and Celsius, use the top left button. Activate the data hold function by pressing the D/H button on the front panel while the thermometer is in the food until the number begins to flash. Press the button again to release the temperature.

The MAX hold function is triggered by pressing the power and temperature buttons simultaneously. This action clears the memory so you can place the thermometer on a dishwasher rack and run a normal wash cycle. After it's removed from the dishwasher, you can press the temperature button for about three seconds to view the maximum recorded temperature. Press the button again for about three seconds to return the device to normal.

    At last an accurate thermometer! In the past, I have not been able to get a true reading when roasting a standing rib, lamb rack, etc. Others were not fast enough; therefore not accurate.
