What is your experience of measuring current with a multimeter?

Place the red pen on the desired current level and the black pen on the common end, and then connect it in series to the circuit under test. Amazing experience.

You must pay attention to the amount of voltage and current, and you are also afraid that you will be electrified, and you may be hurt if you are not careful, so be very careful and don't get distracted.

Using a multimeter to measure the current, I was very nervous and scared, and the current measurement was not a joke.

A multimeter is a tool used to measure voltage, current, and resistance, so if you have time and conditions, you can try it yourself.

Measuring current with a multimeter is often not so clear, understand, because this operation is very troublesome.

To understand how the current works, and the process of measuring is very complicated, I feel like a physics student after the measurement.

There is a small point to pay attention to, that is, do not touch the metal part of the watch pen, so as not to introduce human body resistance and cause measurement errors.

A small reminder is not to touch the metal part of the watch pen, so as not to introduce resistance into the human body and cause measurement errors.

Actually, if I use this, I will find it very troublesome, because the operation is very troublesome, and then I don't know much about this thing.

What is the experience of this indescribable? But you can only try it for yourself, who will know.

Not yet with a clamp ammeter.

It is still necessary to use a regular instrument, even if the operation is wrong, there will be no danger.

1. The gear should be consistent with the type of current to be measured. That is, according to the type of AC and DC of the current to be measured, the correct gear is selected, alternating current.

Compatible with AC gear and direct current.

Corresponding to DC gear.

2. Choose the appropriate range, otherwise, it is very likely to cause the multimeter to be burned.

If you do not know the size of the current to be measured, you should choose the maximum range. For example, a digital multimeter with a 20 amp range can measure the current of kilowatt electrical.

3. Connect the multimeter in series on the live line of the electrical appliance. To do this, the first step is to disconnect the electrical switch. The second step is to unplug the plug and connect the meter in series; The third step is to plug in the plug and close the switch. At this point, the reading of the multimeter is sought.

4. Note: It is very dangerous to use this method to measure the current of high-power electrical appliances, and it is easy to burn the meter. It is recommended to use a clamp ammeter.

This makes it safe and easy to do.
