Tensão AC Referência de Precisão Transmille 3000AC

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.


- Calculable AC voltage reference source
- Accuracy in the order of 10ppm
- Traceable to any DC voltage multimeter with suitable accuracies
