- Abstract:
- In this paper is presented the method for comparison of high value resistance standards by using the modified Wheatstone bridge and picoammeter as current detector, instead of low-impedance current-sensing transimpedance amplifier. Basically, the resistance ratio r can be measured on nominal levels 1:1, 10:1 or 100:1, ensuring the traceability chain from the reference standards of 10 MΩ and 1 GΩ for the range of interest 10 MΩ to 100 GΩ.
