Microwire-wound resistors in high value resistance measurements in VNIIM

VNIIM provides traceability of high-resistance measurements using single and transfer resistance standards comprising resistors wound with a cast microwire in glass tegument (CMW). Accuracy of 100 kOhm - 10 GOhm measurements is of ppm order and is confirmed by a number of key and bilateral comparisons. Resistance unit transfer from 1 GOhm to 1 (100) TOhm is carried out using T-shaped imitators made of microwire resistors.
