Digital Multimeter ADCMT 7482

Description

The 7481/7482 is an 8½-digit digital multimeter with high resolution of 0.01 ppm, equipped with DC voltage, DC current and resistance measurement functions. It is suitable for use in research and development fields or calibration organizations, and calibration of inspection systems for electronic components or semiconductors.
The 7481/7482 achieves high-resolution measurement such as 10 nV for DC voltage measurement, 100 fA for DC current measurement and 1 μΩ for resistance measurement, and also guarantees high relative accuracy 5 ppm per year for voltage measurement and 8 ppm per year for resistance measurement. The 7482 also has AC measurement capability, and AC voltage measurement can be made from 10 Hz to 2 MHz using the True RMS method.
In addition, the self-calibration function allows high-accuracy measurement at any time, and external calibration can be performed with a smaller number of standards.
