How to use a multimeter

Usage steps: 1. Prepare the multimeter and select the appropriate gear; 2. Insert the red and black test leads into the correct jack of the multimeter; 3. Connect the test leads of the multimeter to the object being measured; 4. Read the measurement results; 5. After the measurement is completed, switch the multimeter to the "OFF" position or turn off the power.

A multimeter is a multi-functional measuring instrument that can be used to measure voltage, current, resistance and other parameters. The following are the general steps for using a multimeter:

1. Get your multimeter ready and select the appropriate setting. According to the parameter to be measured (voltage, current or resistance), switch the multimeter to the corresponding gear.

2. Insert the red and black test leads into the correct jack of the multimeter. Generally speaking, the red test lead is inserted into the "VΩ" jack (for measuring voltage, resistance and continuity), and the black test lead is inserted into the "COM" jack (a jack shared by all gears, generally used for grounding).

3. Connect the multimeter’s leads to the object being measured. When taking measurements, make sure the multimeter's leads are connected correctly to avoid short circuits or open circuits.

4. Read the measurement results. Based on the readings of the multimeter, determine the voltage, current or resistance value of the object being measured.

5. After the measurement is completed, switch the multimeter to the "OFF" position or turn off the power.

It should be noted that when using a multimeter, avoid connecting the test leads reversely or short-circuiting to avoid damaging the multimeter. At the same time, be particularly careful when measuring high voltage or large current to avoid accidents. In addition, before using the multimeter, check whether its appearance is intact and whether the knobs and switches are flexible and reliable. If the multimeter malfunctions or is damaged, it should be stopped immediately and sent for repair.
