Overview

Unleash the power of precision with the Automated Voltage Divider System—a game-changer in the world of voltage measurement. The system boasts unmatched versatility and accuracy, perfect for meeting the rigorous demands of laboratory environments. With its self-balancing ratio instrument, you can easily scale between a Josephson-calibrated 10-V reference and any voltage between 1 mV to 1200 V. Say goodbye to manual calibration, as automatic self-calibration guarantees ratios to nine significant digits with linearity deviations of less than 0.02 ppm.

The system comprises of two units—the MI model 8000C Binary Voltage Divider (1 mV to 10 V) and the model 8001C (10 V to 1200 V). Plus, a 10 V source, a detector, and a 10 V reference for unparalleled traceability. The MI model 8000C comes equipped with a built-in 20-channel scanner, enabling you to measure up to twenty 10 voltage references automatically. With 5 input ranges, the model 8001B is versatile and can handle a range of measurement requirements. Both units are controlled by the MI 8000C operating software, making automatic measurements a breeze.

* We have attempted to include all reasonable considerations for our uncertainty budgets but your uncertainty budgets should be re-assessed considering your environment, operating conditions and metrological needs. As this is a ratio device, the results that we show can easily be improved upon.
** Lower Voltages, e.g. 100 mV, 10 mV, 1 mV the resolution of the DMM (Detector) becomes the dominant uncertainty.
