精密交流電壓和電流測量變得輕鬆

5790B 交流測量標準是一款多功能交流測量和傳遞標準，，由於它兼具熱傳遞標準的準確性和數字多用表的易用性，絕對交流電壓測量不確定度低至± 24 ppm (1 年，23 ± 5 ℃ )，因此可用於滿足福祿克計量校準部5730A、5720 和5700A 多功能校準器；5522A、5502A、5520A 和5500A 多產品校準器；其他校準器、放大器，如52120、精密交流電壓和電流輕鬆測量5725A 和5205A/5215A，以及傳遞標準和交流電壓表等交流電壓、交流電流和寬帶性能全面校準的要求。5790B 可涵蓋600 μV 至1000 V 的交流電壓範圍以及10 Hz 至1 MHz 的頻率範圍，寬帶電壓選件將頻率範圍更可擴展至30 或50 MHz。

5790B 可與Fluke A40B 電流分流器組合在一起使用，直接顯示電流測量結果，無需人工計算。5790B 既可單獨作為測量設備使用，也可與外部直流標準源進行比對作為傳遞標準使用。無論哪種情況，通常極為繁瑣的開關切換將由5790B 自動進行，並在醒目的6.5 英寸全彩色電容觸摸屏上顯示測量獲得的交流/ 直流偏差。

Precision ac voltage and current measurements have never been this easy

The 5790B AC Measurement Standard is a multi-purpose 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 (one year, 23 °C ± 5 °C). The 5790B is designed to meet the complete ac voltage, ac current and wideband verification requirements of the Fluke Calibration 5735A, 5720A, and 5700A Multifunction Calibrators; 5522A, 5502A, 5520A, and 5500A Multi-Product Calibrators; plus other calibrators, amplifiers like the 52120, 5725A and 5205A/5215A, and transfer standards and ac voltmeters.

The 5790B covers an alternating voltage range of 600 μV to 1000 V, and a frequency range of 10 Hz to 1 MHz. Wideband voltage options extend frequency range to 30 or 50 MHz.

The 5790B in combination with the Fluke A40B Current Shunts now allow you to make direct, absolute or relative current measurements without the need to perform any calculations.

The 5790B may be used alone as a measurement device or as a transfer standard when compared to an external dc source. In either case the normally tedious switching and calculations are performed automatically by the 5790B, and the resulting ac/dc difference is displayed directly on the easy-to-read 6.5-inch full-color capacitive touch screen display.
