Usage Precautions:
1. Do not touch the probes directly with your hands to avoid electric shock and ensure personal safety during testing.
2. Before use, inspect the test probes to ensure there is no damaged insulation or exposed metal.
3. Do not use the current and voltage ranges interchangeably to prevent damage to the instrument.
4. It is best to remove the batteries when not in use for a long time to prevent battery corrosion of other internal components of the instrument.
5. If you do not know the magnitude of the voltage or current to be measured, start with the highest range and then select the appropriate range based on the measured value.
