Use a multimeter should pay attention to the following matters:

1)Measuring current and voltage can not spin the wrong gear. If you mistakenly use electric block or current block to measure voltage, you can easily burn meter. When the meter is not in use, it is best to block a spin to the ac voltage top gear to avoid damage due to improper use.

2)When measuring DC voltage and DC current, pay attention to "+" "-" polarity, do not pick the wrong. If found pointer to open reversal, both immediately swapped bar table to avoid damage to the pointer and header.

3)If you do not know the size of the measured voltage or current, you should use the highest gear. And then choose the appropriate gear to test, in order to avoid excessive damage to the hands deflected header. The closer the gear selected measured value, the more accurate the measured value.

4)When measuring resistance, do not hand the ends (or two sheet metal parts of the rod) touched element naked to avoid body resistance and the measured resistance in parallel, the measurement results are not accurate.

5)When measuring resistance, such as the two tables short stick, tune "zero ohm" knob to the maximum. Pointer is still not up to 0:00, this phenomenon is usually due to insufficient battery voltage caused by the table, you should put a new battery can only be accurately measured.

6)When the meter is not in use, do not spin the resistance profile, because there are a battery, such as easy to make two tables accidentally shorted rods collide not only consume the battery, even when serious damage to the meter.
