The Research on the High-precise Measuring Method of the DC Bridge and Resistance Box
LV Guang-ming · Quality and Technical Supervision Research · 2013
When using the geometric chain bridge to measure resistance value 100 Ω and below, its accuracy could not reach 0.0005 error level. Applying the method of the measurement of incomplete balance and dummy zero, especially for standard resistance of its value 100 Ω and below, it can eliminate the effects of parasitic potential. The experimental consequences demonstrated that the measurement results could satisfy with 0.0005 error level.
