编号：毕业设计说明书题目：脉冲信号参数测试仪院（系）：电子工程与自动化学院专业：电子信息科学与技术学生姓名：xxxxxxxxxxxx学号：xxxxxxxxx指导教师：xxxxxxxxxxxxxx职称：xxxxxxxxxxxx理论研究实验研究工程设计工程技术研究软件开发2013年5月20日摘要脉冲参数测试仪是在信号类常用的一种仪器，用它可以测量峰峰值、有效值、频率、上升沿和下降沿时间，占空比等的仪器。

这种功能比较齐全的仪器现在大多数都是比较大型的台式的，手提便携式的功能还没那么完善，便携式的比较少，能测得东西也没那么多，而且便携式的测量精度没有台式的测量精度高。

现在便携式的测量仪器普遍用的就是万用表，可以测量直流电压、电阻、电流、电容等等。

本次是用超低功耗的控制芯片MSP430F5438A做为主控芯片，可以测量峰峰值、频率、占空比、上升沿和下降沿时间的参数，由于板子做得不怎么好，所以测的量精度不高。

Keep pipe and tubing lengths to a minimum with inside clean and free of dirt and chips. Pipe joint compounds should be used sparingly and applied only to the male pipe - never into the female port. Do not use PTFE tape to seal pipe joints - pieces have a tendency to break off and lodge inside the unit, possibly causing malfunction.2.Install unit so that air flow is in the direction of arrow. Installation must be upstream of and close to devices it is to service (valve,cylinder, tool etc.). Mounting of regulators may be in any position;mounting of filter/regulators must be vertical as shown in figure.3.Gauge ports are located on both sides of the regulator body for your convenience. It is necessary to install a gauge or pipe plug into each port during installation.4.To protect regulator units against rust, pipe scale, and other foreign matter, install a filter on the upstream (high pressure) side as close to the regulator as possible.Miniature Filter / RegulatorManual Drain Filter(Relieving)Miniature & Economy Regulators(Relieving)Operation of Regulator1.Before turning on air supply , turn adjusting handle counterclockwise until compression is released from control spring. Then turn on air supply and adjust regulator to desired secondary pressure by turning adjusting handle clockwise. This permits pressure to build up slowly,preventing any unexpected operation of the valve, cylinders, tools,etc., attached to the line. Adjustment to desired secondary pressure can be made only with primary pressure applied to the regulator.2.To decrease regulator pressure setting, always reset from a pressure lower than the final setting desired. For example, lowering the secondary pressure from 550 to 410 kPa (80 to 60 PSIG) is best accomplished by dropping the secondary pressure to 350 kPa (50PSIG), then adjusting upward to 410 kPa (60 PSIG).Operation of Filter / Regulator1.Both free moisture and solids are removed automatically by the Filter / Regulator.2.Manual drain filters must be drained regularly before the separated moisture and oil reaches the bottom of the element holder. Automatic drain models (pulse drain) will collect and dump liquids automatically .They are actuated when a pressure drop occurs within the filter.3.The filter element should be removed and replaced when the pressure differential across the filter is excessive.Service!Caution: SHUT OFF AIR SUPPLY and exhaust the primary and secondary pressure before disassembling unit. (Units may be serviced without removing them from the air line.)Servicing Regulator:Note: See Figure 1, 2, & 3 to aid with this procedure.1.Unlock the adjusting knob by pulling upward (with the unit in an upright position.) Then turn adjusting knob counterclockwise until compression of the control spring has been removed.2.Remove the bonnet from body. Then remove o-ring (7), piston, lip seal (9), and control spring to service the bonnet subassembly.Unscrew seat (8) to service the poppet (17), return spring (5), and /or poppet seal (6).Note:On filter / regulator units, the poppet assembly & poppet returnspring may be accessed by removing filter element.3.Clean old grease from unit and inspect seals for sign of wear (nicks,cuts, and scratches). Repair kits are available which contain the parts which are typically replaced.4.Apply a light film of grease to all seals and sliding surfaces using the grease packet supplied with repair kit.WARNINGTo avoid unpredictable system behavior that can cause personal injury and property damage:•Disconnect electrical supply (when necessary) before installation,servicing, or conversion.•Disconnect air supply and depressurize all air lines connected to this product before installation, servicing, or conversion.•Operate within the manufacturer’s specified pressure, temperature,and other conditions listed in these instructions.•Medium must be moisture-free if ambient temperature is below freezing.•Service according to procedures listed in these instructions.•Installation, service, and conversion of these products must be performed by knowledgeable personnel who understand how pneumatic products are to be applied.•After installation, servicing, or conversion, air and electrical supplies (when necessary) should be connected and the product tested for proper function and leakage.

They are suitable for use in normal industrial environments, but should not be located in areas where they could be subject to direct sunlight, an impact blow, nor temperatures outside of the rated range. As with most plastics, some chemicals can cause damage. Polycarbonate bowls should not be exposed to chlorinated hydrocarbons, ketones, esters and certain alcohols. They should not be used in air systems where compressors are lubricated with fire resistant fluids such as phosphate ester and di-ester types.Metal bowls are recommended where ambient and/or media conditions are not compatible with Polycarbonate bowls. Metal bowls resist the action of most such solvents, but should not be used where strong acids or bases are present or in salt laden atmospheres. Consult the factory for specific recommendations where these conditions exist.TO CLEAN POLYCARBONATE BOWLS USE MILD SOAP AND WATER ONLY! DO NOT use cleansing agents such as acetone, benzene, carbon tetrachloride, gasoline, toluene, etc., which are damaging to this plastic.!。
