Fluke 5790AAC Measurement StandardDescriptionFluke 5790A AC Measurement StandardFrequency range: 10Hz - 1MHz; AC voltage range: 70µV - 1000V. Unit also compatible with a 40 current shunts, and a wide band voltage option extends frequency range to 30MHz.Fluke 5790A/AN OPT 03 Measurements/Features:The 5790A covers an alternating voltage range of 700 µV to 1000V, and a frequency range of 10Hz to 1 MHz. A wideband voltage option extends frequency range to 30 MHz to meet the calibration requirements of Fluke 5700A, 5720A and 5100 Series Wideband Options.The 5790A is also compatible with Fluke A40 and A40A Current Shunts, which permit you to make ac/dc current transfer measurements up to 20A.The 5790A may be used alone or as a transfer standard with an external dc source. In either case the normally tedious switching and calculations are performed automatically by the 5790A, and the resulting ac/dc difference is displayed directly on the easy-to-read vacuum fluorescent displa
