Measurement standards available at the Centre:

The National standard of DC voltage unit 1 V and 10 V with standard uncertainty 20 nV. The standard is based on Josephson effect and the voltage is defined by means of fundamental physical constants and frequency. The National standard of the scale of DC Voltage in the range 10 V - 1000 V. The scale is derived from the primary standard based on Josephson effect through the resistance divider and DC comparator. Standards are maintained at the SMU Quantum Standards and Direct Quantities Laboratory.

The National standard of Electrical resistance of nominal value 1 Ohm. The standard consists of group of seven wound resistors. The scale derived from the unit covers the range 0.1 m - 10 T. The National standard of Electrical capacity of nominal value 10 pF at 1000 Hz is formed by two standard capacitors GR 1408. The scale derived from this unit covers the range 1 pF - 100 µF at frequency 1 kHz. Standards are maintained at the SMU Electrical Resistance and Capacitance Laboratory.

The National standard of RF voltage is based on the thermistor and thermoelectric measurement conventers, in which the effect of RF energy is detected. The range covered by the standard is (0.1 - 1) with frequencies (0.05 - 1000) MHz. The standard of RF power is based on the thermoelectric measurement heads, in which the effect of RF energy is detected. The range covered by the standard is (1 - 20) mW up to frequency 18 GHz. Standards are maintained at the SMU High-frequency Quantities Laboratory.

The standard of Root-mean-square of AC voltage and current is based on thermoelectric comparator FLUKE 540 B. The covered range are: for U ef (0.1 - 1000) V at frequencies (40 Hz - 40 kHz) and Ief up to 20 A at frequency 50 Hz. The standard of the AC power and energy is based on AC/DC comparator, the DC voltage calibrator datron 4808, the set of standard resistors and on the inductance voltage divider. It civers range Uef up to 220 V, Ief up to 5 A at frequency 50 Hz. Standards are maintained at the SMU Low-frequency Quanitities Laboratory.
