DC resistance traceability is provided by the Quantum Hall Resistance Standard and AC resistance traceability is provided by calculable AC resistors. While standard capacitors at TÜBİTAK UME are calibrated by the BIPM, standard inductors are calibrated at the primary level by using a Maxwell-Wien Bridge constructed by TÜBİTAK UME.
DC resistance measurements can be performed from 100 µΩ up to 100 TΩ. While DC resistance measurements up to 1 GΩ are performed by using commercial resistance bridges, resistance measurements between 1 GΩ and 100 TΩ are carried out by a Wheatstone Bridge set up in the Impedance Laboratory.
AC resistance traceability is provided by calculable AC resistors. The AC values of the calculable resistors can be determined by calculation while their DC resistance values are determined by using the Quantum Hall Resistance Standard and Cryogenic Current Comparator. AC resistance measurements are generally used for RLC meter calibrations. These measurements can be carried out between 10 Ω and 2 MΩ
The traceability of capacitance is obtained by means of Fused-Silica standard capacitors that are calibrated by BIPM. Andeen Hagerling AH2500A and AH2700A capacitance measurement bridges are used for capacitance calibrations. Capacitance measurements can be performed from 1 pF up to 1 mF. Capacitance calibrations above 1 µF are carried out by using four terminal pair capacitance measurement bridges set up in the laboratory. Measurement frequency for capacitance measurement is up to 30 MHz for Agilent 16380 type capacitors.
Traceability of inductance measurements is obtained by the Maxwell-Wien inductance measurement bridge, which is set up in the laboratory, from AC resistance and capacitance units. Inductance measurement range is between 100 µH and 10 H, however inductance measurements in the order of nH can be carried out by means of recent studies in the laboratory.
AC voltage ratio measurements are usually used for inductive voltage dividers and strain gauge measurements. The traceability is provided by primary level inductive voltage ratio measurement bridge set up in the laboratory.
