用户手册 Unilyzer 902/ 901介绍 现在，数量越来越多的非线性负载例如电脑、办公设备和频率转换设备接入到电网之中。这 类电器设备对电网中的电能质量造成不好的影响，同时，往往这些设备对电网中的干扰也较 老型设备更加敏感。 由此产生了对先进便携式电能质量测量仪器的需求。现代电力工程师繁忙而实际的工作对测 量仪器提出了另一项重要的需求，即：易于操作！电能质量测量仪器必须简单、直观、易于 安装，方便取得测量结果，从而制订如何改善电能质量的行动计划。 Unilyzer 902 / 901 采用防尘防雨的 IP65 封装，是户外型仪表，可以测量所有电能质量参数， 包括长时间同时测量塌陷/浪涌和瞬变。Unilyzer 902 / 901 的设计适合任何电网场合，例如供 电分局、远程通信设施、工厂和商业建筑等。Unilyzer 902 / 901 为满足新的通信趋势要求，设 置了多种通信选择，可以用普通的 RS-232，内置调制解调器（选件）或以太网（选件）。这 样的设计使 Unilyzer 902 / 901 既是便携式电能质量分析仪，又可作为在线式电能质量监测仪 （它与在线式电能质量监测仪 UP-2210 使用了同样的监测系统软件），这充分体现了“便携 仪器是在线监测系统的补充”理念。 祝贺您选择了我们的 Unilyzer 902 / 901！如果您对我们的仪表有任何问题，请直接联系我们或 向我们的本地代表处询问。 顺颂商祺, 瑞典联合电力公司
尚沃采暖产品使用说明
感谢您购买尚沃采暖产品。
您购买的尚沃采暖产品在出厂前已进行了测试和检验以保证其产品质量,希望您能使用满意。
在使用本产品前,请您仔细阅读使用说明书。
由于不遵守使用说明书中规定的注意事项,所引起的任何故障和损失均不在厂家的保修范围之内,厂家亦不承担任何相关责任。
请妥善保管好使用说明书。
如有疑问,请与当地的经销商联系。
一、尚沃采暖产品低温辐射供暖系统优点：⑴舒适性尚沃采暖产品低温辐射电热供暖系统是以红外线低温辐射为主要能量传递方式的产品。
试验证明人体处在低温辐射环境中，就如同置于阳光下，人体的实感温度要高于室内空气温度2—3℃，从而提高了生活环境舒适度。
同时在低温辐射条件下，室内空气的对流速度大幅度降低，使室内减少灰尘，无噪音，室内无冷点和热点，温度均衡，使人无干燥感，温度柔和如阳光般感觉。
尚沃采暖电热板产生的远红外线波长在6—18μm区域内，人长期处在这样的环境中可以改善人体微循环，促进新陈代谢，增强细胞活力，同时有调节神经系统和呼吸系统，舒筋活血，提高人体免疫力等功能。
⑵经济性尚沃采暖产品低温辐射供暖系统供暖效果好，升温快。
由于实现了分户、分室供暖，可根据气温和需要随意调节各室温度，亦可节约运行费用。
系统效率高，当室温设定为16℃时，能达到20℃的取暖效果，室温每降低一度可节约5%的能源。
由于室内周围物体温度高于空气温度，在短期关闭供热系统时，室内周围物体散发的热量会起到保持室温稳定的作用。
试验表明低温辐射电热系统停电6小时，室温仅下降2℃。
⑶安全性尚沃采暖产品的生产符合GB/T 19001-2000—ISO 9001:2000标准，并通过国家红外及工业电热产品质量监督检验中心直检，以及相关《家用和类似用途电器的安全通用要求》GB4706.1—1998、《家用和类似用途电器安全室内加热器的特殊要求》GB4706.23—1996标准的检验。
产品绝缘强度高、阻燃、防水、防潮、耐腐蚀、免维修、使用寿命长（通过10万小时老化试验）。

第二章 使用说明 第一节 开始前的检查
开机前应先检查各旋钮开关动作是否正常，天线及电源是否妥当。 一. 面板上接扦件：
1. 检查一下天线架设是否妥当。收听。
耳机阻抗为 600Ω，如果用其他耳机插入也可收听，但由於阻抗不匹配，收听效果(响 度，清晰度等) ，将变坏些。 二. 面板上的旋钮和开关： 1. 波段开关正反向旋转是各波段定位应正确，然後放在准备收讯的波段。 2. 频率调谐旋钮在名波段度盘标线范围内应运转自如，度盘有”锁紧”旋钮可以锁定。 3. 带宽选择开关，三个位置应跳步清晰，然後放在”宽”位置。 4. “报话” 开关有三个位置：报，话 和 晶校，旋钮在”报”位收第幅报，在”话”位置收话 和调幅报，，旋钮在”晶校”位时可容配合校正使用，校正频率度盘的刻度；同时也可 防止接收机输入端击穿，起强讯号保护作用。 5. “校正” 在保护罩内，报话开关在晶校位，旋开保护罩，可用螺丝起止旋动校正，使指 针对准相应的校准点刻度。 6. 自动增益开关，为控制自动增益断接用。 7. 照明小开关控制照明灯，少用照明灯可节约用电。 8. “射频增益” 旋钮用以控制高放和中放的增益。旋钮在 180˚范围内应运转平滑。 三. 电源检查： 使用电池盒时，应注意电池正负极接法是否正确(电池负极与电池盒的弹簧相接触) ； 使用交流供电时，应检查交流换能器 110/220 选择开关位置是否正确，整机接上电後， 电压指示表应指示在 9.5~12.5 伏(绿色区域内) 。

Packages Features and Benefits– Operation down to 2.5V– Micropower consumption for batterypowered applications– High sensitivity for direct reed switchreplacement applications– Omnipolar, output switches with absolutevalue of North or South pole from magnet 3 pin SOT23 (suffix SO) 3 pin SIP (suffix UA)Functional Block Diagram Application Examples–Solid-state switch– Handheld Wireless Handset Awake Switch – Lid close sensor for battery powered devices –Magnet proximity sensor for reed switch replacement in low duty cycle applicationsChopper stabilized amplifier stage2．DescriptionThe SS239 Omnipolar Hall effect sensor IC is fabricated from mixed signal CMOS technology. It incorporates advanced chopper-stabilization techniques to provide accurate and stable magnetic switch points.The circuit design provides an internally controlled clocking mechanism to cycle power to the Hall element and analog signal processing circuits. This serves to place the high current-consuming portions of the circuit into a “Sleep” mode. Periodically the device is “Awakened” by this internal logic and the magnetic flux from the Hall element is evaluated against the predefined thresholds. If the flux density is above or below the B OP /B RP thresholds then the output transistor is driven to change states accordingly. While in the “Sleep” cycle the output transistor is latched in its previous state. The design has been optimized for service in applications requiring extended operating lifetime in battery powered systems.The output transistor of the SS239 will be latched on (B OP ) in the presence of a sufficiently strong South or North magnetic field facing the marked side of the package. The output will be latched off (B RP ) in the absence of a magnetic field.Typical Application CircuitSEC's pole-independent sensing technique allows for operation with either a north pole or south pole magnet orientation, enhancing the manufacturability of the device. The state-of-the-art technology provides the same output polarity for either pole face.It is strongly recommended that an external bypass be connected (in close proximity to the Hall sensor) between the supply and ground of the device to reduce both external noise and noise generated by the chopper-stabilization technique. This is especially true due to the relatively high impedance of battery supplies.Internal Timing CircuitPin Definitions and DescriptionsSOT Pin №SIP Pin №Name Type Function1 1 VDD Supply Supply Voltage pin2 3 OUT Output Open Drain Output pinGroundpin3 2 GNDGroundTable 1: Pin definitions and descriptionsAbsolute Maximum RatingsParameter Symbol Value UnitsSupply Voltage (operating) V DD 6 VmASupply Current I DD 5Output Voltage V OUT 6 VOutput Current I OUT 5mA85°CtoOperating Temperature Range T A -40150°CStorage Temperature Range T S -50toESD Sensitivity - 4000 VTable 2: Absolute maximum ratingsExceeding the absolute maximum ratings may cause permanent damage.

CMOS makes this advanced technique possible. The CMOS chip is also much smaller than a bipolar chip, allowing very sophisticated circuitry to be placed in less space. The small chip size also contributes to lower physical stress and less power consumption.Installation CommentsConsider temperature coefficients of Hall IC and magnetic, as well as air gap and life time variations. Observe temperature limits during wave soldering.
