Pneumatic Connections – Option 50E: Zero/Span Calibration Valves  
SAMPLE GAS SOURCE:   
Attach a sample inlet line to the sample inlet port.  The SAMPLE input line should not be more than 2 meters 
long. 
  Maximum pressure of any gas at the sample inlet should not exceed 1.5 in-hg above ambient pressure 
and ideally should equal ambient atmospheric pressure. 
  In applications where the sample gas is received from a pressurized manifold, a vent must be placed on 
the sample gas before it enters the analyzer. 
CALIBRATION GAS SOURCES:  
SPAN GAS:  
  Attach a gas line from the pressurized source of calibration gas (e.g. a bottle of NIST-SRM gas) to the 
span inlet. 
  Span gas can by generated by a M700E Dynamic Dilution Calibrator.   
ZERO AIR:  
  Zero air is supplied internally via a zero air scrubber that draws ambient air through the IZS inlet. 
INPUT GAS VENTING:  
The zero air supply and sample gas line MUST be vented in order to ensure that the gases input do not exceed 
the maximum inlet pressure of the analyzer as well as to prevent back diffusion and pressure effects. These 
vents should be: 
  At least 0.2m long;  
  No more than 2m long and;  
  Vented outside the shelter or immediate area surrounding the instrument. 
A similar vent line should be connected to the VENT SPAN outlet on the back of the analyzer. 
EXHAUST OUITLET   
Attach an exhaust line to the analyzer’s EXHAUST outlet fitting.  The exhaust line should be: 
  PTEF tubing; minimum O.D ¼”; 
  A maximum of 10 meters long; 
  Vented outside the analyzer’s enclosure.
