Multimeter purchase and use precautions
Pointer Multimeter
The so-called pointer multimeter, that is, the pointer swing angle to display the corresponding value. At present, the pointer multimeter is basically not much on the market, the most classic or Nanjing MF47 pointer multimeter, this multimeter is well loved by people. Pointer multimeter with pointer to indicate the number, although the reading is not too convenient, but according to the pointer deflection angle to judge the components good or bad.
Digital Multimeter
The so-called digital multimeter is a multimeter with an LCD screen that displays values directly. Digital multimeter is now the mainstream instrument, reading is more convenient, and it is more intelligent. Various voltages, currents, resistance size values are directly displayed on its LCD screen, at a glance. And some digital multimeter can not distinguish between gears, can automatically select the range.
How to choose and buy
If it is only for family measurement, for example, to detect whether the sockets at home have electricity, whether various electrical appliances leakage. Then there is no need to buy some high-precision meters, and there is no need to buy a multimeter with many functions. For example, some multimeter can measure the size of capacitance, for home use, there is no need to buy with this function. Only need to buy a 20-30 yuan between the multimeter can meet the requirements, for example, shown in the picture below this, only need 30 yuan to hand, small and convenient.
If it is used for simple home appliance repair, such as the usual repair of a small home appliance, electric fans, kettles, washing machines and other such appliances. You can consider buying a multimeter with the function of measuring capacitance. Because in the repair of electric fans, generally need to measure the size of the fan start capacitance, using it can determine the capacitance is good or bad.
If used for precision occasions, the multimeter measurement value accuracy requirements are higher. Then the domestic victory and Unidux instrument has not been able to meet the use of requirements, which will need to use the Fluke instrument. Used partners should know, Fluke instrument price is more expensive, but its zero degree and product quality that is very high.
