1. If the “ ” symbol appears on the LCD , it means that the battery power is insufficient. Please replace the battery to maintain the accuracy of the test.
2. Loosen one screw on the battery cover of the thermometer, take off the battery cover, and replace it with four 1.5V (SIZE AAA) UM-4 R03 batteries.
3. When the TASI600 / 601 dual-input K thermocouple wire digital thermometer is not in use for a long time, please take out the battery from the thermometer and avoid storing it in a place with high temperature and high humidity.
Periodically use a soft damp cloth dipped in a neutral detergent to gently wipe the case, do not use emery cloth or solvents with dissolving power to wipe.
