摘要
为正确利用精密数字多用表具有的噪声抑制能力强、稳定性高、线性度好、分辨力高以及采样速率快等优点,对其进行进一步开发,利用比较、直接测量和间接测量等方法,可使其替代检测器、比较仪,在直流电压、电阻、电流等参数的校准/检定和测试工作中发挥更大作用。
The precision digital muhimeter has the characteristics of high noise inhibiting ability, stability, linearity, resolution, and sampling rate. Based on these characteristics, with the methods of comparing, direct measurement and indirect measurement, multimeter can be used in place of detector and comparator, to calibrate and test the DC parameters such as DC voltage, DC current, and DC resistance.
