  • Agilent 34401A Service Guide.pdf

    Agilent 34401A Service Guide.pdfIEC Measurement Category II includes electrical devices connected to mains at an outlet on a branch circuit. Such devices include most small appliances, test equipment, and other devices that plug into a branch outlet or socket. The 34401A may be used to make measurements with the HI and LO inputs connected to mains in such devices, or to the branch outlet itself (up to 300 VAC). However, the 34401A may not be used with its HI and LO inputs connected to mains in permanently installed electrical devices such as the main circuit-breaker panel, sub-panel disconnect boxes, or permanently wired motors. Such devices and circuits are subject to overvoltages that may exceed the protection limits of the 34401A. Note: Voltages above 300 VAC may be measured only in circuits that are isolated from mains. However, transient overvoltages are also present on circuits that are isolated from mains. The Agilent 34401A are designed to safely withstand occasional transient overvoltages up to 2500 Vpk. Do not use this equipment to measure circuits where transient overvoltages could exceed this level. Additional Notices Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC This product complies with the WEEE Directive (2002/96/EC) marking requirement. The affixed product label (see below) indicates that you must not discard this electrical/electronic product in domestic household waste. Product Category: With reference to the equipment types in the WEEE directive Annex 1, this product is classified as a "Monitoring and Control instrumentation" product. Do not dispose in domestic household waste. To return unwanted products, contact your local Agilent office, or see www.agilent.com/environment/product for more information. Agilent 34138A Test Lead Set The Agilent 34401A is compatible with the Agilent 34138A Test Lead Set described below. Test Lead Ratings Test Leads - 1000V, 15A Fine Tip Probe Attachments - 300V, 3A Mini Grabber Attachment - 300V, 3A SMT Grabber Attachments - 300V, 3A Operation The Fine Tip, Mini Grabber, and SMT Grabber attachments plug onto the probe end of the Test Leads. Maintenance If any portion of the Test Lead Set is worn or damaged, do not use. Replace with a new Agilent 3413

  • 热计量表MBUS总线接线标准

    热计量表MBUS远传总线接线标准1.M-BUS介绍M-Bus(是Paderborn大学的Dr.Horst Ziegler与TI公司的Deutschland GmbH和TechemGmbH共同提出的,)专门用于公共事业仪表的总线结构,称Meter-Bus,简称M-Bus.M-Bus仪表总线属于局域网(local Area Net-work,简称LAN),是处于同一幢建筑或方圆几公里远地域内的专用网络,被用于连接远程监控计算机和工作站、测量仪表等设备,以便资源共享和数据传输。M-Bus仪表总线具有LAN的3个基本特征:(1)范围,(2)传输技术,(3)拓扑结构。LAN具有星形、环形和总线形拓扑结构。M-Bus一般采用总线形拓扑结构。如下图M-Bus仪表总线可以满足由电池供电或远程供电的计量仪表的特殊要求。当计量仪表收到数据发送请求时,将当前测量的数据传送到主站,(主站可以是手持单元、计算机或其它终端),主站定期地读取某幢建筑中安装的计量仪表的数据。一般而言,挂接在仪表总线上的计量仪表的数目可达数百个,数据传输距离达数千米。在总线上传送的数据具有高度的完整性和快速性。通信线选择通常选择2芯1.0mm2的RVVP多股铜线线,电源及通信线复用。网络最远距离不宜超过1000m,最大负载数量不宜超过256户。安装注意事项
