How to measure the resistance value accurately with digital multimeter?

Answer:

A multimeter is a portable instrument for measuring various items. It can be used to measure AC voltage and DC voltage,Current, resistance, etc. In addition, it can also roughly judge the electrode and performance of capacitors, transistors and other components. Widely used in electrical maintenance and inspection. Today's multimeter has more and more functions, such as measuring inductance, capacitance and frequency,Transistors, parameters, etc., so they are called "multimeter"". The common multimeter is divided into two categories: pointer, multimeter and digital multimeter.
Digital multimeter than analog multimeter is more convenient, and it is more accurate than the Analog Multimeter, such as fluke multimeter, measurement accuracy of general models can reach the 0.2 level, while the Analog Multimeter only the highest level 0.5, is generally 1.5, the two are not in a sort of. In addition, some fridrik multimeter resistance gear can adjust zero, namely, the multimeter cast in the resistance block, two rod short circuit, a small button click the multimeter behind the measuring resistance is well adjusted.
The range of digital multimeter is its own automatic adjustment, measuring the resistance when the selection knob to measure the resistance block, then directly to two table rod at the two ends of the resistance (a firm), multimeter will automatically display the measured resistance.
