Calibration of electrical measuring instruments

Electrical calibration includes:

• AC and DC voltage from 0 to 1000 V with the best accuracy of 0.018 % and 0.001 %.
• AC and DC current from 0 to 30 A with the best accuracy of 0.05 % and 0.01 %.
• AC and DC current up to 3000 A with the current coil, the accuracy of 0.3 %.
• AC and DC power from 0.4 mW to 4.8 kW with the best accuracy of 0.05 % and 0.06 %.
• AC and DC power up to 900 kW with the current coil, the accuracy of 0.03 %.
• Resistance from 0 Ω to 1 TΩ with the best accuracy of 0.002 % and 0.1 %.
• Capacitance from 10 pF to 100 uF with the best accuracy of 0.05 %.
• Inductance from 10 uH to 10 H with the best accuracy of 0.1 %.
• Frequency from 0.1 Hz to 20 MHz with the best accuracy of 0.005 % and 0.01 %
