Line impedance stabilisation network hm6050 - 2 电源阻抗稳定网路
Line impedance stabilisation network 电源阻抗稳定网路
Results were also run for different high ( relative to the line impedance ) impedance values , including 900 ohms 此结果也在不同(相对于线路阻抗)的阻抗值上运行了,包括900欧姆。
Furthermore , the phone line is continually cheaked by the unit so that changing line impedances due to weather or other factors are automatically compensated 另外,装置仍持续性地检查电话线路,以自动补偿由于天气或其他因素而造成线路阻抗的变化。
A type of micro - ohmmeter based on the technique of current reversed 4 - line impedance measurement is designed , which can be testified to meet the requirement and have a good repeated accuracy 摘要设计一种基于四线制电流倒向技术的微弱电阻测量仪,经实验验证,该测量仪可以很好地满足测量要求,并具有良好的重复测量精度。
