The 5790B AC Measurement Standardis an ac voltage and current measurement or transfer standard designed for the most demanding calibration applications. It combines the accuracy one 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 plus-or-minus 24 ppm (one year, 23 degrees C plus-or-minus 5 degrees C).
The 5790B is designed to meet the complete ac voltage, current, and wideband verification requirements of the Fluke Calibration 5730A, 5720A, and 5700A Multifunction Calibrators; 5522A, 5502A, and 5500A Multi-Product Calibrators; plus other calibrators, amplifiers like the 5725A and 5205A/5215A, transfer standards, and ac voltmeters.
