Don't test metal，Don't wear gloves. 【About Maintenance】 1. The probe of the diamond thermal conductivity meter is very sensitive and requires careful protection. When not in use, the protective cover should be covered. 2. When the ready indicator is very dark, it means that the battery will be exhausted and the battery should be replaced in time. 3. If the instrument will not be used for a long time, please remove the battery. 4. For accurate detection, it is recommended to calibrate once a year.
