How do electricians choose a multimeter that suits their own needs?
A multimeter is one of the essential tools for electrical workers or enthusiasts of electronic circuits. When choosing a multimeter, it is necessary to make the decision based on the actual situation. All brands of multimeters have common functions, and the best choice is the one that suits you the most.
For example, for electricians, they often use the AC and DC voltage functions of the multimeter. The resistance range, continuity buzzer range, and capacitance range are also frequently used. As long as the voltage range, resistance range, and capacitance range are sufficient for their needs, it will be okay.
If it is used for electronic circuits, in addition to meeting the above conditions, it should also have a range for measuring transistors and a range for measuring temperature. Especially for the capacitance measurement range, it must meet the measurement requirements. There are many capacitors on the circuit board with a capacity of 1 picofarad. Therefore, the capacitance measurement range of the multimeter must be able to measure the components with small capacities on the electronic circuit. For some multimeters, when measuring capacitance, it is necessary to insert the leads of the capacitor into the capacitance measurement port on the meter for measurement. For some multimeters, there is no need to insert them into the meter for measurement. Just switch the range to the capacitance measurement range, and you can directly measure the capacitance value of the capacitor with two test leads.
Multimeters come with manual ranging, automatic ranging, and also those that are compatible with both manual and automatic ranging. The advantage of automatic ranging is that it can prevent the multimeter from being burned out due to setting the wrong measurement range. Of course, the price of multimeters with automatic ranging is higher than that of those with manual ranging. In short, there are many brands and models of multimeters, and choosing the one that suits your own use is the best.
