Before using the thermometer, please read the operating safety instructions and instructions.
When the surface measurement Voltage exceeds 24V DC/AC, the measurement needs to be stopped to avoid clicks.
Do not use in the microwave to avoid burning.
Before replacing the battery, be sure to unplug the temperature test lead from the thermometer to maintain safety.
1. If the battery is insufficient, please replace the battery to maintain the accuracy of the test.
2. When the thermometer is not used for a long time, please remove the battery from the thermometer and avoid storing it in a high temperature place.
3. Regularly use a soft damp cloth dipped in neutral detergent to gently wipe the shell, not use an abrasive cloth or solvent with soluble ability to wipe.
4. Repeatedly bending the thermocouple line will break it. Avoiding bending thermocouple wires, especially near corners, can extend the life of thermocouple wires.
