Following is a simple, step-by-step procedure for executing a specified-value span calibration of 
a Model 9116 Intelligent Pressure Scanner. For the purposes of this example, it will be assumed 
that an upscale pressure of 14.9800 psi is available from a dead weight tester for the calibration 
of 15 psi internal transducers.  All sixteen channels are 15 psi full scale. 
 
Description 
Model 9116 Command 
Ensure that valves are in RUN/CAL mode (default) 
[w1200] 
…  normal data acquisition 
 
Perform Re-zero calibration first 
See Section 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 
 
[w0C00] for RUN 
With a deadweight tester, apply 14.9800psi to the 
appropriate module CAL and CAL REF inputs [or optionally 
to RUN inputs] 
 
Delay for settling of pneumatic inputs 
 
Verify measured data reads near expected full scale

Instruct module to calculate new gain coefficients for all 16 
channels
