To minimize the possibility of overpressure damage, multi-range 
9816 modules are manufactured to make use of the CAL (x) port of 
the LOWEST installed pressure range. 

 

Summary 

 
Following is a simple, step-by-step procedure for executing a “full scale” span calibration of a 
9816 Intelligent Pressure Scanner.  It is assumed that all channels in the unit have the same 
full-scale pressure range.  Optional commands are shown within brackets [ ]. 

 

Description  

TCP/IP Data 

Insure that valves in RUN/CAL mode (default).  

[w1200] 

…  normal data acquisition 

 

Perform Re-zero calibration 

see Sec.  4.2.2 

Place the module calibration manifolds into the CAL 
position if this is the desired pressure application input.  
The RUN position may be a better choice for modules with 
transducers having different ranges. 

[w0C01] for CAL pos. 
 
[w0C00] for RUN pos. 

Apply exact full scale pressure to the appropriate module 
CAL and CAL REF inputs [or optionally to RUN inputs] 

 

Delay for settling of pneumatic inputs 

 

Verify that measured data reads near expected full scale

Instruct module to calculate new gain coefficients for all 16 
channels

Store new gain coefficients into transducer nonvolatile 
memory
