Chroma 66202数位功率表符合EN50564:2011/ IEC62301:2011标准针对功率量测要求
EN 50564:2011为标准针对家电类及办公室使用的电子产品，在无载状态下的功率量测规范及后续量测资料分析处理方式做定义。EN 50564:2011的内容是取得于IEC 62301:2011标准，因此这两个标准在功率量测规范及后续量测资料分析处理方式是相同的。
Chroma 66202数位功率表是可以完全符合EN 50564:2011在B.2.1章节对于功率量测设备所规范的要求，除此之外66202也可以完全符合4.4.1章节对于功率量测不确定度要求部份。基本上66202已通过KEMA实验室检验为符合IEC 62301:2005针对功率量测需求的功率表，目前已确认在300V x 100mA档位的功率量测准确度规格为0.1% Reading + 0.05% Range是小于EN 50564:2011所定义的不确定功率0.02W。
Chroma 66202对于EN 50564:2011在量测资料分析处理方式部份也提供了完整的解决方案，66202的电脑图形化介面软体(Softpanel)提供使用者容易操作的界面，可以依照标准所要求的方式来分析量测资料，同时可提供测试报告，记录所有的相关参数，如总谐波失真率、波峰因数、电压、电流、频率、有效功率，视在功率、功率因数等。

66200系列数位式功率表是用来量测单相交流电源的功率及其他电压电流参数，适用于大部份的电机电器产品。不同于一般传统用类比线路的方式，66200系列使用了类比转数位化16 bits的高解析度，zui高 250KHz的取样频率，及高速的数位讯号处理(DSP)技术。比起其他厂牌同等级的功率表，它能提供更多功能，及更快速量测出稳定及精确的数值。
66200系列数位式功率表系列有四个显示视窗，同时提供不同参数读取，使用者可以很容易的选择想读取的数值。每个视窗的七段显示器提供5 digits的量测解析度。另外于后背板有USB或GPIB介面供使用者选配，做数位控制使用。另外，机器的体积为2U的高度及一半标准机柜宽度，适用于系统整合。
型号66201为基本功能的机种，专为小功率产品测试使用，例如电池充电器、电压适调器、LCD监视器等。可量测参数包括了 :1. Voltage : Vrms, Vpeak+, Vpeak-2. Current : Irms, Ipeak+, Ipeak-3. Power : Watts, Power Factor, Apparent Power VA, Reactive Power VAR4. Current Crest Factor Frequency
型号66202数位功率表内部有两组量测电流感测器，可满足小电流的量测精准要求，也可适用大电流的应用。除了型号 66201可量测的参数外，66202还可以测量涌浪电流(Inrush Current)，总谐波失真率(Total Harmonic Distortion)及能量(焦耳)。因为多了这些功能，66202更能满足研发部门或品管部门的量测需求。
66200系列不仅提供平均模式，也提供了移动视窗法，让使用者设定时间长度，量测时会计算视窗内所有资料，所以不会遗漏任何讯号。除此之外也提供能量累积模式(INTEGRATION MODE)来量测功率，符合能源之星测试要求。
提供量测电压和电流的总谐波失真率(TOTAL HARMonIC DISTORTION)的功能，可直接显示在功率表上。而能源之星有些测试需要验证输入交流电压包含到 13 阶谐波成份的失真率需小于2%，66202数位功率表也提供了能让使用者定义谐波阶数N的设定，
使用者可以设定一个电流准位来触发开始量测电流的时间点A，另外可设定另一个参数延迟(DELAY)，用来延迟真正撷取电流波形的时间，可帮助忽略掉刚开始不需要的波峰B。还有另一参数TIME，为撷取波形的时间长度，这样66202数位功率表就会量测到C点的波峰电流。
提供图形化控制软体，透过USB或GPIB介面在电脑上控制及读取资料，还可观察电压电流波形、记录随时间变化的关系图，也可将长时间量测值储存至档案后供分析，符合能源之星要求每秒量测持续5分钟，再取平均值的要求。甚至66202可以量测谐波成分，进行IEC61000-3-2电流谐波限制的前测作业。
另外提供电源效率测试软件，整合了66202功率表、电子负载及交流电源，可依照能源之星的规范简单设定后，即可自动按法规步骤进行测试，并产生报告，相当适合研发及品保单位对电源的验证使用。
可选购A662003量测用治具组 (250V/15A)，方便接线测试。66202可选购50A/100A的外挂电流转换器来增加电流量测范围。
