Voltage reference 3000AC

PRECISION REFERENCES AND STANDARDS • Calculable AC voltage reference source • Accuracy in the order of 10ppm • Traceable to any DC voltage multimeter with suitable accuracies The 3000AC provides laboratories with a fully traceable AC voltage source with accuracies in the order of 10ppm that can easily be verified with a DC voltage multimeter with accuracies in the 4ppm to 10ppm region. Using the latest in DAC technology and zener references, a digitally generated waveform with a calculable RMS value is generated at fixed frequencies up to 1kHz, enabling verification of high accuracy multimeters at better than 4:1 test uncertainty ratio. As the 3000AC is calibrated before use, there is no long-term drift to consider, and using a fully solid state design provides unrivalled accuracy and simplicity in use.
