它与 5725A 升压放大器、52120 跨导放大器和 5205A/5215A 放大器(现已过时)兼容。所有这些都可以通过 MET/CAL Plus校准软件实现自动化 。
该5700A和5720A为五功能的校准旨在满足最苛刻的电气校准工作。它们提供直流和交流电压、电流和电阻。宽带电压选项可将整体交流带宽扩展至 10 Hz 至 30 MHz。两者都与 5725A 和 5205A/5215A 放大器兼容。自 1988 年推出以来,5700A 在性能、可靠性和质量方面赢得了全球声誉,因此它是整个政府和行业的首选校准器。
自 1988 年投入使用以来,5700A 经历了不断改进,成为 5700A 系列 II,这是福禄克有史以来生产的最可靠的高精度校准器之一。5700A 被视为全球校准标准,可提供高价值以及涵盖 5 1/2 至 7 1/2 位数字万用表的准确度。此外,它还提供与 5720A 相同的易用性、低拥有成本、坚固耐用的设计、简化的支持和建立信心的功能。
5700A 和 5720A 的技术指标均通过选择的置信水平进行说明。现在,您可以使用 Fluke 传统上发布的保守的 99% 规格,或者在许多国际程序中推荐的更激进的 95% 规格。除了允许您用少量风险换取更好的性能之外,95% 的置信水平规格还允许更轻松地进行测量比对。对于任何输出,按下 SPEC 键即可获得这两种规格。
5700A 和 5720A 都具有工件校准功能。只需要三个人工标准——一个 10V dc 参考和 1Ω 和 10 kΩ 电阻参考来校准所有范围和功能到完整的规格。前面板说明提示操作员进行连接并输入每一步。校准器控制整个过程,只需大约一个小时,而使用传统方法需要几个小时。
在此过程中,外部工件的指定值被传输到 5720A 内的大量多维参数中。校准器接管建立比率和进行比较以及控制测量过程的手动计量功能。
为确保信心,5700A 和 5720A 可以根据自己的内部标准进行自我检查,以确保一切都按预期工作。这些结果可以打印出来或下载到计算机上。
5720 和 5700 校准器可以通过使用 5725 升压放大器提高其性能。5725A 放大器将最大直流和交流电流增加到 11A,用于校准流行的低成本手持数字万用表的高电流范围。它还将校准器的交流伏赫兹产品扩展到 30 kHz 时的 1100V 和 100 kHz 时的 750V,以满足高精度台式和系统仪表的校准要求。
Product Description:
The 5700A and 5720A are five-function calibrators designed to address the most demanding electrical calibration workload. They source direct and alternating voltage and current and resistance. A wideband voltage option extends overall ac bandwidth to 10 Hz to 30 MHz.
In service since 1988, the 5700A has undergone continuous improvements to become the 5700A Series II, one of the most tested and reliable high precision calibrators Fluke has ever produced. Considered the calibration standard worldwide, the 5700A delivers high value as well as accuracy covering 5 1/2 to 7 1/2 digit dmms. Plus it offers the same ease of use, low cost of ownership, rugged design, simplified support and confidence building features as the 5720A.
Specifications for both the 5700A and 5720A are stated with a choice of confidence levels. Now, you can use the conservative 99% specifications that Fluke traditionally publishes, or more aggressive 95% specifications recommended in many international procedures. In addition to allowing you to trade a small amount of risk for better performance, 95% confidence level specifications allow easier measurement intercomparisons. Both specifications are available at a press of the SPEC key for any output.
Both the 5700A and the 5720A feature Artifact Calibration. Only three artifact standards -- a 10V dc reference and 1Ω and 10 kΩ resistance references are required to calibrate all ranges and functions to full specifications. Front panel instructions prompt the operator to make connections and inputs each step of the way. The calibrator controls the process, which takes only about an hour, compared to several hours using traditional methods.
During the process, assigned values of an external artifact are transferred to a large array of multidimensional parameters within the 5720A. The calibrator takes over the manual metrology functions of establishing ratios and making comparisons, as well as controlling the measurement process.
To assure confidence, the 5700A and 5720A can check themselves against their own internal standards to assure everything is working as expected. Those results can be printed out or downloaded to a computer.
The 5720 and 5700 calibrators can increase their performance with the use of the 5725 boost amplifier. The 5725A Amplifier increases maximum direct and alternating current to 11A for calibrating the high current ranges of popular low-cost, handheld DMMs. It also extends the calibrator’s alternating Volt-Hertz product to 1100V at 30 kHz and 750V at 100 kHz to cover the calibration requirements of high accuracy bench and system meters.
