Which multimeter for electricians is suitable for home use and is cost-effective?
It is still the analog MF-47 model. Although it is old and has never been improved, many data are still based on this old analog watch, especially in the repair of home appliances. As an electrician, it is more convenient to use an analog meter, because generally electricians do not have high requirements for accuracy, but they require quick measurement of continuity, and the reading of a digital meter jumping around is relatively slow. I work as an electrician now, and I often use an MF47 multimeter and two digital meters. When I first bought it, I thought it was new, but over time, I found it impractical. It has been in the locker for many years.
Multimeters for home use do not require high accuracy. You can just buy a digital multimeter, which is very cheap for tens of yuan. For industrial and maintenance purposes, it is better to use an analog multimeter. When using digital measurements, the digital response is too slow and is not suitable. For general measurements, just buy a meter with an accuracy of 2.5, and the price is very cheap. The price of a high-precision watch will be much higher. Whether it is worth buying depends on your needs.
The frequency of household use is low, and the measurement accuracy requirements are not high. A small analog multimeter will suffice. If you have the ability to use a microampere meter to make a general meter, it is very simple. If you add five diodes, a resistor and a two-pole double The toggle switch can be made into a dual-purpose meter for 22O voltage and continuity measurement (of course a small battery is required)
Determine the range and accuracy of the multimeter according to the voltage, current, and resistance range you are measuring. The multimeter suitable for home measurement has a voltage range of AC60v-500v; DC1v-600v; current 0.5MA-10A; resistance 1Ω-10kΩ. It is recommended to use the MF47 pointer multimeter.
