Active Guarded Wheatstone Bridge for High Resistance Measurements up to 100 T Omega at TUBITAK UME

2018    Erkan, Omer; Gulmez, Gulay; Turhan, Enis; Hayirli, Cem

We present an active guarded Wheatstone bridge, developed at TUBITAK UME, for high resistance measurements between 100 M Omega to 100 T Omega up to 1000 V. The guarded box connections and special low noise cables were used to reduce noise and leakage currents causing measurement errors. This has enabled us to perform stable measurements at higher resistor values.
