Use this multimeter for: household outlets, fuses, wiring, general-purpose batteries, vehicle battery and charging system, automotive circuits and more.Note:
1. When the Meter is working at an effective voltage over 60V in DC or 30V rms in AC, special care should be taken because there is a danger of electric shock.
2. Before using the Meter, inspect the exterior casing. Do not use the Meter if it is damaged or if all or part of the exterior casing is removed. Look for cracks or missing plastic. Pay special attention to the insulation around the connectors.
3. If you have mistakenly connected the red test lead to the 500mA selection, then used this meter to test larger current(like 10A) or higher voltage, it might probably burn out the wires even the meter.
4. If you are the beginner, you should have known some basic physical concecpts and basic methods of using a meter, you also should have read the user manual carefully and known the consequences of misuse because any misuses will probably cause serious results.
