Pressure Systems, Inc. Model 9116 User’s Manual

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	[w0C01] for CAL
if this is the desired pressure application input. The RUN
position may be a better choice for modules with	[w0C00] for RUN
transducers having different ranges.
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	[rFFFF0]
Instruct module to calculate new gain coefficients for all 16	ZFFFF 14.98
channels
Place calibration manifold back into the RUN position	w0C00
Store new gain coefficients to transducer non-volatile	w09
memory
… continue normal data acquisition
