SAFETY NOTE
Please pay attention to the warning which indicates a situation or action that poses a danger to the user and may cause damage tothe instrument or the equipment under test. The instrument strictly follows GB4793.1 safety requirements for electric instruments and safety standard IEC61010 to design and produce, which is under the safety standards of double insulation, overvoltage standards (CAT II 1000V, CAT III 600V) and pollution level 2. Please read the operation manual carefully before operation, or the protection function will weakened or lost.
3-1. Please check whether the insulation surface of the test leads is intact before use it. If you found the insulation surface of the test leads or the cover of the meter is obviously damaged, or you think it can’t work anymore, please do not use the meteragain.
3-2. When you using the test leads, your fingers should be put after the finger protective part.
3-3. When the voltage under tested is higher than DC 36V and AC 25V RMS, be careful to prevent electric shock.
3-4. Do not operate the meter if battery case and back cover is not fixed.
3-5. The signal under tested should not be over range, in case to avoid the electric shock.
3-6. It is forbidden to change the range by the range knob under measurement. 
3-7. Do not test the voltage by connecting the current terminal or at the current range.
3-8. When replacing fuses, please use the same type and specification fuses.
3-9. Do not change the inner circuit of meter, to avoid damage of the meter. 
3-10.When the LCD displays symbol, replace the batteries in time to ensure the measuring accuracy.
3-11. Please comply with local and national safety regulations. Wearing personal protective equipment (such as approved rubber gloves, face masks, and flame-retardant clothing etc.) to prevent the injury from electric shock and arc when charged conductors are exposed.
3-12. Do not store and operate the meter under the condition of high temperature, high humidity, combustible (flammable),
explosive and strong magnetic place.
3-13. Wipe the case with a damp cloth and detergent, do not use abrasives and alcohol etc.
