Specification: Origin: Mainland China Hign-concerned Chemical: None Precautions for use: 1. During the test, do not touch the probe directly with your hands to avoid electric shock and ensure personal safety. 2. Before use, check the test probe to ensure that there is no damaged insulation layer or exposed metal. 3. Do not use the current and voltage ranges alternately to prevent damage to the instrument. 4. It is best to remove the battery when not in use for a long time to prevent the battery from corroding other internal components of the instrument. 5. If you do not know the size of the voltage or current to be measured, start with the highest range and then select the appropriate range according to the measured value.
