I would like to buy a multimeter that is more accurate than this.
For friends of electricians, multimeter convenient and practical essential. Many friends in the selection of multimeters feel that the accuracy is more important, and even require multimeters to be a few thousandths of the accuracy. In fact, I think that for ordinary maintenance work, accuracy is really not as important as you think, of course, except for the maintenance of certain precision circuit boards.
For example, measuring the voltage of a motor, the voltage is 380V and 383V for the judgement of the line fault has no effect. Multimeter is not a cutting-edge technology, different brands of multimeter error is not much difference. I think that compared to accuracy, it is more important to be of high quality, durable, not easily broken, and not fall off the chain at critical moments.
There are two main types of multimeters: pointer meters and digital meters.
Pointer multimeter input impedance is low, low accuracy, but it is strong anti-interference ability, can visually reflect the size of the change.
Digital multimeter input impedance is high, high accuracy, intuitive readings, feature-rich, such as measuring voltage, current, temperature, capacitance what can be. Because the digital meter uses instantaneous sampling, so it is easy to appear digital jump phenomenon.
If you are a novice to start, I recommend starting with the pointer multimeter. Although the beginning of contact with the pointer multimeter will feel the reading trouble, but used to it, you will love her. A lot of circuit testing, in fact, do not need to read, just need to see the pointer to that side of the deflection can be. If it is a digital meter, you also need to compare the results before and after the measurement to know the circuit.
MF50 and MF47 are both classic models of pointer multimeter, and MF47 models are generally used for the introduction and teaching of electricians. As for the pointer multimeter brand, "Nanjing Jinchuan Electric Meter Factory (formerly Nanjing Electric Meter Factory)" is an old brand, although the new model is not so solid, hold in the hand light, but the quality of the pointer multimeter is also very good, it is worth having.
