3. 200 300 CIM CM 200 300 PS 210 215 218 can acquire one channel of data To collect data from more detectors in an instrument you can use a Star 800 MIB or a 9050 detector UV 1 Initial Wavelength Setting The UV 1 ProStar 320 wavelength setting that is programmed at time zero in the method will take effect when the method is run not when the method is activated Since the system monitors the baseline noise before the start of the method run the monitoring may be done at a wavelength different from that in the method This means that the calculated noise could be substantially different from what would have been calculated using the method wavelength To work around this problem enter manual control at the start of each session and manually set the UV 1 wavelength to the value in your method Alternatively create a short start up method which sets the wavelength and does not acquire data Use this method for your first run in a sample list End Monitor in Wrong State In certain circumstances you may get the message End Monitor in Wrong State in the message log of an instrument containing a ProStar Dynamax System This message results from a communication error with the PS 21x or SD 1 CIM and indicates that the Star Workstation was unable to properly monitor the noise signal before a run When this happens the run will continue but no data will be saved The most likely cause of this error is that your serial port is overloaded
