Question:

Can you tell me the advantages and disadvantages of the multimeter and the direct current bridge for measuring resistance?

Can you tell me the advantages and disadvantages of the multimeter and the direct current bridge for measuring resistance?

Answer:

The bridge is accurate.Multimeter is two wire, four wire bridge should be, can eliminate the measurement of small resistance test, resistance, multimeter doesn't work. You can look at both two-wire and four wire testing methods
1 accuracy, general measurement procedures should be simple, certainly not the multimeter measurement accuracy is not the same, with another advantage is the measurement function table than the bridge, in addition to measure the resistance can also measure the voltage, current, digital meter can also be measured C, L and PE, measurement the signal frequency and so on.
In general, DC bridge resistance element adapted to accurately measure resistance smaller, measurement accuracy can reach 0.01, the measuring steps than 12000 measuring resistance is relatively complex, and the multimeter to measure resistance measurement only to 0
