DC & Low Frequency

The Absolute Calibration Volt is derived from a Fluke 7000 Nanoscan DC Reference System, within twelve months our in-house volt calibration uncertainty will be sub/ppm. A divider system allows the generation and measurement up to 100,000 volts. Our state-of-the art ATE system allows the automatic calibration of most modern Digital Multimeters. DC resistance calibration measurement is by substitution method up to 0.1ohm using the Kelvin Bridge at currents up to 100A resulting in uncertainties from 20ppm. 0.1 to 10kohm is measured using potentiometric techniques with uncertainties from 1ppm. A substitution method completes the range up to 4Tohm. AC resistance calibration using a ratio transformer bridge at 1 k Hz from 0.1 to 10Kohm result in uncertainties of 0.02%.
