PreparationPreparation work must be perfectly pleted by user before installation personnel arrive.1. Requirements for working environment: (1) Analysis room: away from place with corrosive gases (acidic gas, alkalic gas), dust, shock or interference (2) Workbench: stable, 30~50cm away from wall: length width height (min) =(~) (~) (3) Ambient temperature filling of silica wool and agent must be of proper tightness, otherwise gas flow may be impacted. (2) Coat inwall of tube end openings with a little vacuum silicone grease, mount tube to true positionFill purifying agent in oxygen purification tube and analysis gas purification tube as the figure below。 hold down left button and move mouse (Selected characters get blue, called highlighting selection. At this, they can be modified, namely newlyinput characters cover original characters.)。 at this, the software will automatically correct singlepoint coefficient, meanwhile new correction coefficient will be shown in rear of “corrected C/S coefficient”. For confirming the new coefficient, click “save coefficient” (or click “close” to refuse improper coefficient)。 Select all: select all items in current list。 measurement device can be started to verify gas circuit is well sealed by gas charging. High frequency induction heating device can be started for trial analysis only if normality is verified in full.V.

Software introductionAnalysis software of CS206 is based on Windows operating platform, suitable for Windows 2000 and Windows XP (Windows XP preferred).II. Installation of analysis softwareThe analysis software is in associated pact disc. For installing it on puter, click its installation program “setup” and follow installation suggestions (default installation directory: c:\BAOYING TECH\CS ANALYSIS\)。 50Hz177。10% Frequency, 50Hz177?！?77?！?77。2% Power, 5KVA Ground resistance≤4Ω4. Working gas: oxygen concentration 179。2%。 its shortcut icon can turn up on desktop and shortcut launch bar, upon selection during installation.III. System building modeMicroputer system of CS206 adopts upperlower puter technology. PC interface adopts RS232 data exchange technology. These build munication system work mode involving upper and lower puter. Single chip microprocessor is for data acquisition and status control. Upper and lower puter are assembled for data processing management, input and manmachine dialog. Upper puter is a mercial one of known brand. Windows 2000/Windows XP operating system is adopted to support the analysis so
