The following guidelines should be used when installing pressure connections to the Model 
9116
 Intelligent Pressure Scanner modules. 
 
 
●  Always wear safety glasses when working with pressurized lines. 
 
 
  Ensure that user input pressure will not exceed the proof pressure ratings of 
the corresponding instrument transducer.  Applying excessive pressure to 
measurement inputs can permanently damage the pressure transducers. 
 
 
  Ensure that all tubing material is rated for the expected pressure and 
environmental   conditions.  Failure to use the proper tubing material may 
result in ruptured lines and   possible personal injury.  
 
    Ensure all high pressure lines are properly secured. 
 
 
  Place retaining springs over all bulge tube fittings to ensure pneumatic lines 
remain attached and leak free.  Springs should be pushed down on 
connections so that half of the spring length extends past the tube bulge.
 
 
 
 
 
 
 
2.3.6.1 
  RUN Mode Inputs 
 
 
The standard pneumatic tubing plate for the Model 9116 contains sixteen numbered pneumatic 
input channels.  These numbered inputs are attached to corresponding pressure transducers 
inside the instrument and should be pneumatically attached to the pressure measurement 
points under test.   
  
The standard tubing plate also contains an input labeled RUN REF.  The RUN REF input is 
pneumatically connected to the reference side of all internal DH200 pressure transducers.  The 
RUN REF
 connection is used for situations where all channels have one reference pressure.  
The reference pressure may be as high as 250 PSI (1720 kPa).  See the Model 9116 Data 
Sheet for detailed specifications.  This input may also be left unattached to provide atmospheric 
reference pressure.  
 
When using instruments with the reference per channel option (true differential), two pneumatic 
inputs will be provided for every numbered channel.  These inputs are labeled ‘P’ and ‘R’.  The 
P’ connection is the test pressure input.  The ‘R’ connection is the transducer reference input 
pressure. Since each channel has its own reference pressure input, the RUN REF input is not 
provided on the true differential tubing plate. 
 
 
Warning:  Introduction of contaminants or corrosive materials to the module 
pneumatic inputs may damage module transducers, manifolds, and O-ring seals.
