Chapter 4Setup and Calibration4.3 CalibrationCalibration must be done for each combination of time constant and eV per channel thatyou plan to use. The system stores all different sets of calibration values. The calibrationpanel can be accessed from the Setup Menu. The calibration panel allows for Automaticand Manual calibration. The automatic calibration is more accurate than the manualmethod.A log file Calibrat.csv maintains a record of the date and time of each calibration and thecalibration-parameters that were calculated. This file can be accessed through the explorerand is located in the Windows folder. Note that editing this file has no effect on thecalibration as this is simply a log file.4.3.1 When to Calibrate?When to calibrate the system is dependant on numerous factors. Many labs must calibrateon a set schedule for quality control purposes. It is also possible to calibrate on an “asneeded” basis. Checking the calibration can be done in a few ways.‣ Manually place the cursor on a peak center and compare the actual placementwith the theoretical peak position.‣ Noticing when the auto ID fails for peaks that are normally easily identified.‣ The HPD is misfit for all of the major peaks.
