10. Log-on and Calibration Log-on Demonstration

11. Log-on and Calibration  Calibration introduces a known substance into the system.  After the Itemiser 2 identifies the substance, the software adjusts the positions for all the other programmed substances.  Calibration can be affected by changes in temperature, atmospheric pressure, and humidity. What is Calibration?
