Enter the Calibration Password when prompted.All units have the same password.Calibration Password: calFigure 36. Calibration Menu.The Calibration menu includes two distinct areas, Calibration Info and the TemperatureOffsets Table.Calibration Info(1) last calibration date(2) last calibration expiration date(3) calibration index numberThe calibration index number is stored in permanent memory, and incrementedevery time a temperature offset calibration is successfully completed.(4) calibration intervalThe calibration procedure will use the Calibration Interval to calculate theexpiration date for the new calibration. If you need to change the CalibrationInterval, touch the Cal Interval button to program a different interval (in days).(5) today’s dateTemperature Offsets TableA three column table listing the current temperature offsets.Melting Points Offset CorrectionLists the rated meltingpoints of the standardsubstances required by theAcceptability TestLists the currenttemperature offsets usedby OptiMelt to correct thethermometer readingsduring melting pointdeterminationsThree empty boxes used toenter the TOCs for the threeCRSs as calculated in Step10 of the Acceptability TestOptiMelt Automated Melting Point System
