Digital multimeter PK pointer multimeter, who is better!
Multimeter , listen to the name, we know that it has a lot of roles, is the electrician masters * love. General multimeter can measure DC current, AC and DC voltage, resistance, etc., in addition, there are some can measure other parameters, such as AC current, capacitance, inductance, etc., more special can also measure the temperature.
According to the different ways of its display, the multimeter can be divided into digital multimeter and pointer multimeter.
Nowadays, the popularity of the market is mainly digital multimeter, pointer multimeter gradually be replaced.
So why is the digital multimeter more and more popular, while the pointer multimeter is more and more eliminated?
Pointer multimeter internal structure is relatively simple, so relative to the digital multimeter, the production cost is much lower, the function is also relatively small, and the digital multimeter internal is multi-purpose integrated circuits, although the cost is higher than the pointer type, but its function is more, such as capacitance, inductance, frequency, temperature and so on can be measured.
Modern industrial technology is more and more advanced, the times need a multi-functional power detector meter birth, and will become mainstream, pointer type multimeter will naturally be eliminated, but relative to the digital multimeter, it also has its own unique advantages!
First of all, the internal pointer multimeter is generally no amplifier, so the internal resistance is relatively small, which leads to its higher sensitivity.
Secondly, as mentioned above, the internal structure of the pointer multimeter is relatively simple, so the cost is lower.
Finally, the voltage output of the pointer multimeter is higher, and the current is also larger, so it can be very convenient to test the light-emitting diode.
In conclusion, everything has its own advantages, just digital multimeter and pointer multimeter a comparison, the advantages are stronger, so it will become a mainstream product!
