福禄克Fluke 438-II 电机效率和电气性能综合测试仪
Fluke 438-II 电能质量和电机分析仪

438-II 是理想的便携式电机分析测试工具，可帮助您定位、预测、防止和排除三相和单相配电系统的电能质量问题，同时为技术人员提供所需的机电信息，从而有效地评估电机性能。

测定工频电机以及由特定变频驱动系统驱动的电机的关键参数，包括转矩、转速、机械功率和效率
绘制电机降额系数与负载对比图（符合 NEMA/IEC 准则），执行动态电机分析
计算机械功率和效率，无需使用机械传感器，只需连接输入导线，一切便准备就绪
测量电压、电流、功率、视在功率、功率系数、谐波失真和不平衡度等电源参数，以确定影响电机效率的特性
识别暂降、暂升、瞬变、谐波和不平衡等电能质量问题
PowerWave 数据技术可捕获快速变化的 RMS 数据，显示半周期平均值和波形来描述电气系统动态特性（发电机起动、UPS 切换等等。）
波形捕获功能可在所有模式下针对检测到的每个事件捕获 100/120 个周期 (50/60 Hz)，无需设置
自动瞬态模式可在电压高达 6kV 时，在所有相位上同时捕获 200 kS/s 的波形数据
兼容 Fluke Connect?* — 通过仪器在本地查看数据、通过 Fluke Connect 移动应用程序和 PowerLog 430-II 桌面软件查看数据
工业应用安全等级：进户线和下游使用的安全等级为 600 V CAT IV/1000 V CAT III

When we got to the house, Charlie finally spoke.

　　"Um… you'll need to call Renée." He hung his head, guilty.

　　I was appalled. "You told Mom!""Sorry."I slammed the cruiser's door a little harder than necessary on my way out.

　　My mom was in hysterics, of course. I had to tell her I felt fine atleast thirty times before she would calm down. She begged me to come home— forgetting the fact that home was empty at the moment — but her pleaswere easier to resist than I would have thought. I was consumed by themystery Edward presented. And more than a little obsessed by Edwardhimself. Stupid, stupid, stupid. I wasn't as eager to escape Forks as Ishould be, as any normal, sane person would be.

　　I decided I might as well go to bed early that night. Charlie continuedto watch me anxiously, and it was getting on my nerves. I stopped on myway to grab three Tylenol from the bathroom. They did help, and, as thepain eased, I drifted to sleep.

　　That was the first night I dreamed of Edward Cullen.
