Or pointer type MF-47 type, although old, and there is always nothing to improve, but a lot of data is still based on this old pointer table, especially in home appliance repair. Doing electrician is more with the pointer table is more smooth, because the general electrician on the accuracy requirements are not high, but requires rapid measurement of the pass, digital table jumping around the readings are slower. I now do electricians, often use is a MF47 multimeter, digital table has two, just buy when you feel fresh, time long felt impractical, locker for many years.

Family multimeter, accuracy requirements are not high, just buy a digital multimeter can be, dozens of yuan a very cheap. Industrial use and maintenance or pointer multimeter better, with digital measurement of digital reflection is too slow, not applicable. General measurement to buy precision 2.5 level table can be, the price is also very cheap. The price of high-precision table will be much higher, is it worth buying, it depends on the need.

Low frequency of family use, the measurement accuracy requirements are not high, general small pointer on the table, if you have the ability to use a micro-ampere meter head to do a through the table is very simple, if coupled with five diodes, a resistor and a two-knife double-throw knob switch can be made into a 22O voltage and measurement of through the dual-use table (of course, also have to be a small battery).

To determine the multimeter gear and accuracy according to the voltage, current, resistance range you are measuring. Suitable for home multimeter measuring voltage range AC AC60v-500v within; DC DC1v-600v within; current 0.5MA-10A within; resistance 1Ω-10kΩ within. It is recommended to use MF47 type pointer multimeter.
