 Zero/Span Check or Cal With Zero/Span 
Gas in the Sample Port 
The calibration of the instrument can be checked or adjusted using gas coming in the sample 
port. This method is often used when the calibration gas is supplied from the stack sample probe 
or external tank and valve system. This is the calibration method to use if the instrument is 
purchased without the Zero/Span Valve.
