A filter will come with a floppy disk containing data required for the 7500 to calibrate properly. You will

CPU, start at the Wager DCU main menu and select "System Configuration". Then, on the bottom left
select "New Filter". Insert floppy disk into the drive and click "OK" The system will prompt to replace the
file. Click replace. Remove floppy disk and store in proper place.
Filter Calibration Test
From Main Menu, press “Filter Calibration” button. Connect all sensor to the DCU and the laptop. Make
certain the system is turned on, and the DCU has been reset. Press “Calibrate” button with clear light
path. System will prompt to insert the calibration filter and then press “Start.” Allow the system to record
the filter value for approximately 10 seconds. It will stop automatically and check the filter value. The
system will show either one of the following messages: Test Passed, updating calibration date. The
system will automatically update the 7 day calibration date. It will shut down the software for changes to
take effect. If the filter is outside the specified range, the system will display "Test Failed". To re-test,
remove the filter and press the calibration button again. If the failure message continues, contact the
