This field is for entry of the average ozone chamber pressure as indicated by the front panel pressure field during calibration in the FLOW mode SOFT KEY DESCRIPTIONS INIT ALL The INIT ALL soft key will initialize the screen to produce a calibration curve with a slope of 1 and an intercept of zero In addition the Pressure field will be initialized to standard sea level pressure plus 10 PSIG SAVE DATA This soft key is used to record data in the system and update DAC Digital to Analog Converter device 011 DAC 011 is the device used to directly command voltage levels to the ozone generator Once this device has been updated the ozone data in the calibration table is no longer used Once all data is entered and saved you should exit out of ozone calibration to allow the system to use the new data After saving the data all TRUE ozone data will revert to the TARGET ozone data getting the system ready for a second set of TRUE data if necessary In this way the ozone calibration data can be compounded allowing it to be fine tuned for greater accuracy OPERATION When ozone calibration is required you should use the FLOW MODE to run all the calibration points of interest Refer to the OZONE CALIBRATION procedure in the APPENDIX for details Environics Series 9100 25 Revision 8 April 2013 5 7 3 DEVICE ADC Analog to Digital Converter This area is used to enter the calibration data for the different ADC devices in the s
5. A calibration point is really made up of two parts target ozone and total flow With these two parts the system can relate them back to the ozone module flow which is typically 500 sccm and the maximum ozone which is typically 26 PPM at 500 sccm For example an ozone setting of 1 PPM 13 0 slpm is equivalent to 26 PPM 500 0 sccm The formula for computing the command to the ozone module is as follows Target O3 Total Flow Ozone Module Flow Ozone Module 03 Environics Series 9100 24 Revision 8 April 2013 TARGET OZONE The entry for this field is the target ozone value entered in the flow mode When an entry is made in this field the system will use the previous ozone calibration data to compute the Target Volts TARGET VOLTS This is a display only field that shows the voltage applied to the ozone module This value is computed from the Target Ozone Target Flow and the previous ozone calibration data TARGET TOTAL FLOW This field is for entry of the target total flow value used in the flow mode for running ozone When an entry is made in this field the system will use the previous ozone calibration data to compute the Target Volts TRUE OZONE This field is for entry of the actual ozone as measured by your ozone standard while in FLOW MODE TRUE TOTAL FLOW This field should duplicate the flow rate entered into the TARGET TOTAL FLOW column for the respective ozone point PRESSURE
6. In addition the calibrate mode also displays several messages related to the system operation 1 The selected flow calculation method used by the calibration tables single slope and intercept or multi point linear interpolation 2 Whether or not the optional ozone pressure transducer is being used to correct ozone generation 3 Whether or not all flow will be shut off if the actual flow through the system drops below 50 of the target flow Refer to the System Configuration Settings section pg 37 for details on how to change these settings CALIBRATION The system is using a multi point linear interpolation for computing flows Ozone adjust pressure gaug is on Stop flows when low flow detected is on MFC DE FLOW Calibrate Mode Main Menu MFC FLOW The MFC flow soft key allows you to calibrate the Mass Flow Controllers using a flow calibration standard It also allows you to enter calibration data for a pre calibrated flow controller When you press the MFC FLOW soft key you will be prompted to enter the MFC to be calibrated as well as which gas port you are using for your calibration gas SCREEN LAYOUT The MFC FLOW calibration screen shows 11 calibration points each with 5 field columns The first column shows the percent of command in relation to the size of the MFC being calibrated and will be updated by the system whenever a command value is changed The next two columns are for ente
