IS-HF-AccUViewLEDEx-100125 Rev 0 9Calibration ErrorIf this screen is displayed after calibration is complete, the internaldiagnostics have determined that the calibration fluid or the flowthrough cuvette requires replacement. Check the calibration fluid andcuvette and then recalibrate or restore the factory calibration. Theinstrument cannot be used without performing one of these operations.See Restoring Factory Settings section for more information.To recalibrate, press the MODE key and start the calibration sequenceagain.Restore Factory SettingsIf the instrument is unable to perform a calibration due to a low lampoutput, bad calibration standard or a dirty cuvette, the instrument willdisplay CAL and Err on the display. If the problem is determined to bea poor calibration or low lamp, fix the problem and recalibrate. If theproblem cannot be determined, the instrument must be restored to thefactory calibration and configuration settings.To restore factory settings:1. Push and hold the  button.2. Push and release the  button and then release the  button.The instrument has now been restored to it’s original factory settings.Instrument Configuration(CONFIG Mode)The instrument has the ability to be customized at any time duringoperation. CONFIG Mode has been split into sub-menus to facilitateinstrument configuration. While in Configuration Mode, the instrumenthas a time-out feature that automatically returns the system operationto AUTO mode after a 15 minute period.To enter CONFIG Mode:1. Press the MODE/EXIT button until the arrow next to CONFIG isilluminated.2. Press the  button. You are now in CONFIG Mode.3. To exit CONFIG Mode, press the MODE/EXIT button.Selecting the Output (O/P)The first configuration sub-menu is the O/P. The O/P options are:• 4-20 for the 4-20 mA output• 485 for the RS-485 and modbus• OFF if no outputs are required1. Using the  and  buttons, select the desired output.2. Once the desired output has been selected, press the  button toset it.The next prompts will depend on the output selected. For RS-485 andModbus, certain combinations of settings are not allowed and somemenus will not appear based on previous selections.Setting the 4-20 mAIf the 4-20 mA output was selected, you will be asked to set the 4mA(4MA) and 20mA (20MA) %T or ABS limit levels.1. Select the %T or ABS level you wish to assign to the 4MA settingusing the  and  buttons. The factory setting is 90%T or 0 forABS.2. Once the desired level has been selected, press the  button to set it.The 4MA level cannot be set higher than the 20 MA level.3. Select the %T or ABS level you wish to assign to the 20MA settingusing the  and  buttons. The factory default setting is 100%T or2 for ABS.4. Once the desired level has been selected, press the  button to set it.The 20MA level cannot be set lower than the 4MA level.Setting the Error LevelIn case of an error in the AccUView LED Ex, the 4-20 mA reading canbe used to indicate a problem by sending the output to either:• 4.00 mA• 2.00 mA• 0 mA• OFF - In the case of OFF, the 4-20mA is unaffected by any errorcondition. OFF is the factory default setting.1. Select the desired ERLV using the  and  buttons.2. Once the desired level is selected, press the  button to set it.Configuring the RS-485 PortIf the instrument is wired for this option and the I/O selection ischanged to 485, prompts will appear for setting the baud rate and theaddress.Setting the Baud Rate1. Select the desired baud rate (1200, 2400, 4800, 9600 or 19200) foroperation of the I/O using the  and  buttons. Factory setting is19200 baud.2. Once the desired baud rate is selected, press the  button to set it.Restoring the factory settings allows the use of the AccUViewLED Ex with reduced accuracy. The original problem stillexists and must be determined and corrected before accurateoperation of the AccUView LED Ex will be resumed. TheAccUView LED Ex will always reset to %T and factory defaultsafter restoring.NOTICEScreen Display - Setting the Error LevelScreen Display - Calibration ErrorScreen Display - Setting the 4-20 mA limitsScreen Display - Setting the Baud Rate
