Traceable Low Frequency AC Voltage Measurements

Christiaan S. Veldman

Abstract

The International Organization for Standardization (ISO) has developed a set of standards for the calibration of vibration and shock transducers. Method 3 of ISO 16063 part 11, deals specifically with the primary calibration of accelerometers over the frequency range 1 Hz to 10 kHz. Many NMIs have implemented the method over a wider frequency range. One of the difficulties faced by said NMI, is the provision of traceable low frequency AC voltage measurements.<br /> This paper considers low frequency AC voltage traceability options and investigates in more detail a measurement option defined as DC sampled AC measurements. As part of the investigation; 1) a calibration procedure is developed and implemented, 2) the measurement accuracy of the system is demonstrated.
