The following innovative features are included in your Hunter Air Purifier.•High Particulate Efficiency: The HEPA filter will remove 99.97% of 0.3 micron particles from the air that passes through the filter.•Odor Removal: The activated carbon pre-filter helps remove odors such as cooking, smoke,and pet smells from the air. It also traps lint, hair, and other large particles to help extend the life and performance of the HEPA filter.•Ionizer: The ionizer improves the quality of air in the room by releasing negative ions into the air that attract positively charged dust, smoke, and pollen particles.•Quiet: The air purifier has been designed to operate quietly and efficiently. You can choose among three speeds to best meet your needs at different times.•Filter Counters: Filter maintenance is critical to the performance of the air purifier. To help you determine when to change the filters, the pre-filter and HEPA filter, the unit has built inlife counters that keep track of the life remaining of each filter.41913-014Air Purifier ComponentsFig. 1 - Illustration of the Air Filtration SystemHow the QuietFlo ® Air Purification System WorksAs the air is pulled into the purifier, the activated carbon pre-filter absorbs odors and catches large particles. Then, the air travels through the HEPA filter where the smaller particles are collected. Then, the ionizer releases negative ions into the air that attract positively charged dust, smoke, and pollen particles. Finally, the clean, purified air is released back into the room.Fig. 2 - Air Purifier Components RECESS FORFINGERS TOPULL OPEN FRONT GRILL FRONTGRILLFig. 3 - Inside Surfaceof Front GrillGRILLVENTS TAPETABS HOOKPollen & Allergens Odors Bacteria Pre-Filter 99.97% – .3 Microns541913-01Display and Control KeysThe display and control keys allow for easy operation of the air purifier.UP/DOWN KEYS : Adjusts the blower speed and turns the unit on and off.PRE-FILTER RESET : Resets the Carbon Pre-Filter Life Counter.FILTER RESET : Resets the HEPA Filter Life Counter.IONIZER KEY: Turns the ionizer on and off.HEPA FILTER LIFE COUNTERKEYPAD LOCKED INDICATORCARBON PRE-FILTER INDICATOR41913-016Initial OperationThis section provides basic instructions on the use of your air purifier. After following these initial directions, please continue reading this booklet to learn how to operate the more advanced features of your air purifier.Basic Operation of the Air Purifier:1.Take the air purifier out of the box and remove the clear plastic protective bag.Place the unit on a firm level floor.2.Before turning on the air purifier, you need to confirm that the filters are firmly in place and have not become loose during shipping. To check the filters, first open the front grill. Release the front grill by placing your fingers behind the tabs and pulling forward. Refer to Figs. 2 and 3 (pg. 4).3.Next, check the HEPA filter by pressing firmly on all four corners of the filter to ensure that it is fully inserted into the filter opening.4.The carbon pre-filter is mounted inside the front grill with hook tape. Confirm that it properly covers the grill vents. You may notice a few black particles com-ing off the pre-filter. Those particles are part of the odor-removing activated car-bon and will be collected on the filter during use.5.Place the front grill back onto the unit. First, line up the tabs on the bottom of the grill with the openings on the purifier base and then push the top of the grill forward until it is closed. Refer to Figs. 2 and 3 (pg. 4). NOTE: This unit will not operate unless the grill is in the correct position.6.Plug the unit into a 120V electrical outlet and press the UP key. The air puri-fier will start with a low blower speed.e the UP/DOWN keys to adjust the blower speed to the desired level (0 = Off,1 = Low,2 = Medium,3 = High). Refer to Fig. 5.Fig. 5Filter Life CountersThe pre-filter and filter are critical to the proper operation of the air purifier. To help you know when to change the filters, your Hunter Air Purifier has Filter Life Counters that will monitor the percentage of life your filter has left. Although the exact life of the filters de-pends on the environment, the table below gives typical usage times of the filters.Table 2: Typical Usage Times of the FiltersFilter Type Typical UsageActivated Carbon Pre-Filter2000 hoursHEPA Filter8000 hoursThe display shows the percentage of life left since the counter was reset. NOTE: The per-centage level drops in 5% increments.The values of the Pre-Filter and Filter Life Counters are stored in the air purifier’s memory. The unit may be unplugged and moved or stored without losing the Pre-Filter and Filter Counter values.To properly track filter usage, the Pre-Filter and Filter Life Counters should be reset each time the filters are changed. Refer to Changing the Pre-Filter (pg. 9) or Changing the Filter (pg. 10) for instructions on how to reset the counters.Locking/Unlocking the KeypadOnce you enter the desired speed, you may want to lock the keypad to prevent accidental changing of the speed. When the keypad is locked, all keys will be disabled. If you press a key, the Keypad Locked Indicator will be displayed on the screen for 1-2 seconds.To Lock or Unlock the Keypad:1.To lock the keypad, press and hold the UP/DOWN keyssimultaneously for 2-3 seconds. The Keypad Locked In-dicator will appear on the display. Refer to Fig. 6. After releasing the keys, the Keypad Locked Indicator will dis-appear.2.To unlock the key pad, press and hold the UP/DOWNkeys simultaneously for 2-3 seconds. The Keypad Indi-cator will disappear and the keypad will be functional.Fig. 6741913-0141913-018Resetting the Air PurifierIn the unusual situation that the unit or the display is exhibiting erratic behavior, you may want to reset the air purifier. If you still have problems after resetting the air purifier, please contact Hunter for additional assistance (refer to Technical Assistance, pg. 12).To Reset the Air Purifier:1.Unplug the unit for at least 30 seconds.2.Plug the unit back in.Using the IonizerUsing the ionizer improves the quality of air in the room. Negative ions are released into the air and positively charged dust, smoke, and pollen particles are attracted to the negative ions. These particles settle out of the air and can be vacuumed up during normal cleaning.These particles are also more easily captured by the HEPA filter as they pass through the QuietFlo ® Air Purification System. To ensure the best air circulation in the room, we rec-ommend that you place your air purifier six (6) inches away from any walls.To turn the ionizer on or off:1.To turn the ionizer on, press the IONIZER key. The Ion-izer Indicator will appear on the display. Refer to Fig 7.2.To turn the ionizer off, press the IONIZER key. The Ion-izer Indicator will disappear.Fig. 7Cleaning Your Air PurifierProper maintenance of your Hunter Air Purifier will help ensure years of trouble free service.Follow these steps to properly maintain your air purifier:1.Approximately every 90 days, the outside of the unit should be cleaned with a soft,damp cloth.2.If needed, the front grill can be removed from the unit and cleaned with soapy water.Simply remove the pre-filter before exposing the grill to water.3.Follow the instructions in Changing the Pre-Filter and Changing the Filter (pgs. 9 and10) to determine when and how to replace the filters.NOTES:•The air purifier must be unplugged during the cleaning process.•Be sure the unit is completely dry before plugging in and using.•Never immerse unit in water.Changing the Pre-FilterWhen the Pre-Filter exceeds 2000 hours (refer to Filter Life Counters for additional infor-mation, pg. 7), the Pre-Filter Life Counter will display 0% life remaining and the Pre-Filter indicator will flash as a reminder that you should replace the pre-filter. To maintain proper odor-removing capability and overall filtration performance, the pre-filter should be changed every 2000 hours (approximately 6 months of use). If necessary, the pre-filter can be changed more often. Proper maintenance of the pre-filter will help extend the life of the HEPA filter. Refer to Obtaining Replacement Filters (pg. 11) if you need help finding replacement filters.To change the pre-filter and reset the Pre-Filter Life Counter:1.First, turn off and unplug the air purifier.2.Next, remove the front grill.

Power OutputIndustrial VRS Magnetic Speed SensorsDESCRIPTIONPower Output VRS sensors are designed for driving lowresistance loads at large air gaps in applications where larger actuators may be used.Passive VRS (Variable Reluctance Speed) Magnetic Speed sensors are simple, rugged devices that do not require an external voltage source for operation.A permanent magnet in the sensor establishes a fixedmagnetic field. The approach and passing of a ferrous metal target near the sensor’s pole piece (sensing area) changes the flux lines of the magnetic field, dynamically changing its strength. This change in magnetic field strength induces a current into a coil winding which is attached to the output terminals.The output signal of a VRS sensor is an ac voltage that varies in amplitude and wave frequency as the speed of themonitored device changes, and is usually expressed in peak to peak voltage (Vp-p).One complete waveform (cycle) occurs as each target passes the sensor’s pole piece. If a standard gear were used as a target, this output signal would resemble a sine wave if viewed on an oscilloscope.Honeywell also offers VRS sensors for general purpose, high output, high resolution, high temperature and hazardous location applications, as well as low-cost molded versions.FEATURES• Self-powered operation• Direct conversion of actuator speed to output frequency • Simple installation • No moving parts• Designed for use over a wide range of speeds • Adaptable to a wide variety of configurations• Customized VRS products for unique speed sensingapplications• Housing diameter: 5/8 in (M16)• Housing material/style: stainless steel threaded • Terminations: MS3106 connector, preleaded • Output voltage: 70 Vp-pPOTENTIAL APPLICATIONS• Engine RPM (revolutions per minute) measurement onaircraft, automobiles, boats, buses, trucks and rail vehicles• Motor RPM measurement on drills, grinders, lathes andautomatic screw machines• Motor RPM measurement on precision camera, taperecording and motion picture equipment• Process speed measurement on food, textile, paper,woodworking, printing, tobacco and pharmaceutical industry machinery• Motor speed measurement of electrical generatingequipment• Speed measurement of pumps, blowers, mixers, exhaustand ventilating fans• Flow measurement on turbine meters• Wheel-slip measurement on autos and locomotives • Gear speed measurementPower Output2 /sensing5/8 INCH (M16*) SENSORS (All dimensions for reference only. mm/[in]) *Contact Honeywell for availability of metric mounting thread versions.General SpecificationsTest Condition SpecificationsParameter Characteristic Parameter Characteristic Parameter Characteristic Min. output voltage 70 Vp-p Inductance 85 mH max.

网络分析仪简史

网络分析仪简史（60~80年代）如何简化元件表征早期的网络分析仪量化元件的阻抗是非常慢的。

Art Fong 803A VHF桥在50年代是非常具有创新的仪器，第一次直观的给出了未知待测器件的幅度和相位读数。

但是测量起来非常慢而且非常繁琐。

完整的测试装置如下图所示，在获得一个测试频点的结果之前需要一步一步的调整和校准每个仪器的控制。

即使对于一个有经验的用户得出这个结果也需要几分钟，准确量化DUT需要测量大量的不同频点。

过程最耗时的部分之一就是使用已调谐到感兴趣频点的417A VHF接收机平衡803A VHF桥。

第一个改进是将这套系统中的两台仪器用采用全新矢量测量概念的单台仪器HP 8405A代替。

8405A是1966年推出矢量电压表，具有2通道的宽带毫伏表，可以同时测量1~1000MHz的幅度和相位，全量程内具有100mV的灵敏度和0.1 的相位分辨率。

得益于60年代早期采样技术的进展和HP开发的热载流子二极管，8405A这种矢量电压表的概念演化成为一系列仪器，最终成为矢量网络分析仪。

就在8405A推出一年之后的1967年，两种新的矢量电压表被制造出来，音频和中频范围的4800A，RF-VHF频段的4815A。

他们都内置了全频测量所需的信号源，从而将上图所示的装置减少成一台单一的独立仪器。

顶部 4800A，5Hz~500kHz，左下角：4815A 0.5~108MHz，右下角8405A：1~1000MHzS参数的引入其他非常重要的演变是由矢量电压表带来的测量概念。

使得相对于标准参考值的未知阻抗评估成为可能。

不同于先前描述2端口网络的“Y”或者“H”参数，“S”或“散射”参数由输入和输出端口的传输线特征阻抗决定。

分散参数很快成为表征比如RF和微波频段晶体管这样的线性有源器件的标准。

另外，由于S参数可以由50欧姆负载测量获得并用反射系数作为单位，也可以直接描绘在史密斯圆图上。

1967年 8410A 直接史密斯圆图显示最后一步将阻抗随频率变化的函数直接描绘在史密斯圆图上需要2个改进。
