How do electricians choose a multimeter that is suitable for their own use
A multimeter is one of the necessary tools for electrical workers or enthusiasts of electronic circuits, and the selection of a multimeter depends on the actual situation. All brands have the functions of a multimeter, and choosing the one that suits you is the best.
For example, as an electrician, when using a multimeter for AC, there should be more DC voltage, resistance level, on/off buzzer level, and capacitance level. As long as the voltage level, resistance level, capacitance level, and range are sufficient, it is sufficient.
If it is used in electronic circuits, in addition to meeting the previous conditions, there should also be a three-level tube measurement gear and a temperature measurement gear. Especially the capacitance measurement gear should meet the needs of measurement. Many capacitors on the circuit board have a capacity of 1 picosecond, so the capacitance measurement range of a multimeter must be able to measure small capacity components on electronic circuits. Some multimeters measure capacitance by inserting the pin of the capacitor into the capacitance measurement port on the meter. Some multimeters do not need to be inserted into the meter for measurement, as long as the gear is set to the capacitance measurement gear, the capacitance can be directly measured with two probes.
Multimeters have both manual and automatic ranges, and they are compatible with each other. The advantage of automatic range is that it can avoid setting the wrong measurement gear and burning the multimeter. Of course, its price is higher than that of a manual range multimeter. In short, there are many brands and styles of multimeter, and choosing a suitable one for your own use is the best.
