The multimeter bursts and burns out accidentally, how to break it?
First of all, be sure to use the correct gear and range, this is the most basic, do not measure the voltage with the current gear, the meter will burn. If this mistake is careless, it is easy to make.
Second, you must develop good habits.
Double check whether the table is abnormal before using it. It doesn't take long, but it has a great effect. For example, check whether the watch is damaged, whether the numbers or pointers are abnormal, especially when measuring high voltage, be sure to check the watch.
Again, the multimeter must be placed in a place that is not prone to moisture. Keep it dry and neat!
Last but not least, don't use a low-quality multimeter. Counterfeit goods are really the case for multimeters!
When the withstand voltage rating of the multimeter used is not enough, the multimeter will be broken down during measurement to cause a short circuit, which will cause an explosion due to the large current. The reason for the explosion was that the high temperature caused by the excessive current melted and vaporized the insulating material in the multimeter, resulting in local high-pressure gas. That is to say, we often see a puff of smoke that is not released in time. It all happened in an instant, and people must have no time to react. The chance of encountering such a switchboard trip is also very small, because if the time is very short, the switchboard will pass before it has time to react, and it will continue to remain closed.
