Calibrating current sources using A40B Series Current Shunts and the 5790B AC Measurement Standard
The Fluke Calibration 5790B AC Measurement Standard is a multipurpose ac measurement and transfer standard designed for the most demanding calibration applications. It combines the accuracy you would expect from a thermal transfer standard with the ease of use of a digital multimeter. Absolute ac voltage measurement uncertainties are as low as 24 ppm for one year in a 23 °C ± 5 °C environment. The 5790B in combination with the Fluke Calibration A40B Current Shunts allow you to make absolute or relative current measurements that are shown directly on the display as a current readout. This feature provides a very simple method to expand the 5790B’s functionality to make precision current measurements.
