6.4. CALIBRATION MODE 

Press the CAL key to switch the M300E/EM into calibration mode.  In this mode the user can, in conjunction with 
introducing zero or span gases of known concentrations into the analyzer, cause it to adjust and recalculate the 
slope (gain) and offset of the its measurement range.  This mode is also used to check the current calibration 
status of the instrument. 

  For more information about setting up and performing standard calibration operations or checks, see 

  For more information about setting up and performing EPA equivalent calibrations, see Section 10.  

If the instrument includes one of the available zero/span valve options, the SAMPLE mode display will also 
include CALZ and CALS keys.  Pressing either of these keys also puts the instrument into calibration mode.   

The CALZ key is used to initiate a calibration of the analyzer’s zero point using internally generated zero air.   
The CALS key is used to calibrate the span point of the analyzer’s current reporting range using span gas.   

For more information concerning calibration valve options, see Section 5.6 

For information on using the automatic calibration feature (ACAL) in conjunction with the one of the calibration 
valve options, see Section 9.4.
